🌌 1. ब्रह्मांड एवं सौर मंडल (Universe & Solar System) (7 min read)

1.1 Brahmand (Universe) — basic concept

Big Bang Theory (महाविस्फोट सिद्धांत): Brahmand ki utpatti ek bahut chhote, garam, ghane bindu ke vistaar (expansion) se hui maani jaati hai. Brahmand aaj bhi phail raha hai (expanding universe — Edwin Hubble).
Aakashganga (Milky Way / मंदाकिनी): Hamari galaxy. Hamara Sun isi ka ek sadharan taara hai. Sabse paas ki badi galaxy — Andromeda (देवयानी).
Prakash Varsh (Light Year): doori (distance) ki unit hai, samay ki nahi! Prakash ek varsh me jitni doori tay karta hai ≈ 9.46 × 10¹² km.
Sun ke baad Prithvi ke sabse paas ka taara — Proxima Centauri (~4.2 light year). Dhruv Tara (Pole Star / Polaris) — uttar disha batata hai.

1.2 Surya (Sun) — hamara taara

Sun ek taara (star) hai — iski apni roshni hai. Saur mandal ke kul dravyaman (mass) ka lagbhag 99.8% Sun me hai.
Mukhya gas: Hydrogen, phir Helium. Urja ka srot — Nuclear Fusion (नाभिकीय संलयन): Hydrogen → Helium.
Sun se Prithvi ki ausat doori ≈ 15 crore km (149.6 million km = 1 AU). Sun ki roshni Prithvi tak ≈ 8 minute 20 second me pahunchti hai.
Sun ki dikhne wali satah — Photosphere (प्रकाशमंडल); bahari parat Corona sirf poorn surya grahan me dikhti hai. Sunspots (सौर कलंक) — thande, kaale dhabbe.

1.3 8 Grah (Planets) — Sun se kram: "Bu-Shu-Pri-Man-Bri-Shani-Aru-Varun"

Grah	Khaas pehchaan (exam point)
बुध Mercury	Sun ke sabse paas, sabse chhota grah, sabse tez parikrama (~88 din). Koi upgrah (moon) nahi.
शुक्र Venus	Sabse garam grah (ghana CO₂ vayumandal — greenhouse), sabse chamkeela ("Bhor/Sanjh ka taara" — Morning/Evening Star). Prithvi ki "judwa bahan" (size same). Ulti disha me ghoornan (east→west; Sun pashchim se ugta dikhega). Koi moon nahi.
पृथ्वी Earth	"Blue Planet" (नीला ग्रह) — 71% satah par paani. Jeevan wala ekmatra gyat grah. Ek upgrah — Chandrama.
मंगल Mars	"Red Planet" (लाल ग्रह) — iron oxide ki wajah se. Do moons: Phobos & Deimos. Olympus Mons — saur mandal ka sabse ooncha jwalamukhi parvat. India ka Mangalyaan (MOM, 2013).
बृहस्पति Jupiter	Sabse bada aur sabse bhaari grah. "Great Red Spot" (vishal toofan). Ganymede — saur mandal ka sabse bada upgrah.
शनि Saturn	Sundar valay (rings). Sabse kam ghanatva (density paani se bhi kam). Titan — iska sabse bada moon (ghana vayumandal). Sabse zyada gyat upgrahon wala grah.
अरुण Uranus	Axis lagbhag 98° jhuka — "let kar lotta hua" grah. Methane gas se hara-neela dikhta hai. Ise bhi ulta ghoornan (Venus ki tarah) wala mana jata hai.
वरुण Neptune	Sun se sabse door grah (Pluto ke hatne ke baad). Sabse bade moon — Triton.

Aantarik / Parthiv grah (Inner/Terrestrial — chattani): Mercury, Venus, Earth, Mars. Bahari / Jovian grah (gas giants): Jupiter, Saturn, Uranus, Neptune — sab ke paas rings hain.
Pluto (यम): 2006 me International Astronomical Union (IAU, Prague) ne ise Dwarf Planet (बौना ग्रह) ghoshit kiya. Anya dwarf planets: Ceres, Eris, Haumea, Makemake.
Kshudra grah (Asteroids): Mars aur Jupiter ke beech ki patti (Asteroid Belt). Sabse bada — Ceres (ab dwarf planet).
Dhoomketu (Comet — पुच्छल तारा): Barf + dhool; Sun ke paas aane par poonchh banti hai jo hamesha Sun se door (ulti disha) hoti hai. Halley's Comet — lagbhag har 76 saal me dikhta hai (pichhli baar 1986; agli baar 2061).
Ulka (Meteor — टूटता तारा): Vayumandal me ghusate hi jal jaati hai (Mesosphere me). Zameen tak pahunche to Ulkapind (Meteorite). Example: Lonar crater lake (Maharashtra) — ulkapind se bani jheel.

1.4 Chandrama (Moon)

Prithvi ka ekmatra prakritik upgrah; Prithvi se ausat doori ≈ 3,84,400 km. Chand ki roshni (paravartit/reflected suryaprakash) Prithvi tak ~1.3 second me.
Apni dhuri par ghoomne aur Prithvi ki parikrama — dono me lagbhag barabar samay (~27.3 din) → isliye Chand ka hamesha ek hi hissa dikhta hai.
Amavasya se Amavasya (ek chandra maas) ≈ 29.5 din. Chand par vayumandal nahi → aawaz nahi, aasmaan kaala dikhta hai.
India: Chandrayaan-1 (2008) ne chand par paani ke anu (water molecules) ki pushti me madad ki; Chandrayaan-3 ka Vikram lander 23 Aug 2023 ko chand ke dakshini dhruv ke paas utra (23 Aug = National Space Day).

⚠️ Exam Traps:

Sabse garam grah = Venus (Mercury nahi, jabki Mercury Sun ke sabse paas hai).
Light year = doori ki unit. Parsec bhi doori ki unit hai.
Sabse bada upgrah = Ganymede (Jupiter ka), Titan (Saturn) nahi. Titan ghana vayumandal wala upgrah hai.
Pluto ab grah nahi — isliye "saur mandal me kitne grah?" = 8.
Dhoomketu ki poonchh hamesha Sun se ulti disha me hoti hai (solar wind ke karan).

🌐 2. पृथ्वी: अक्षांश-देशांतर, समय, गतियाँ, ऋतुएँ, ग्रहण (8 min read)

2.1 Prithvi ka aakaar

Prithvi poori gol nahi — dhruvon (poles) par thodi chapti, bhoomadhya rekha par thodi ubhri: Geoid (भू-आभ) / Oblate spheroid.
Bhoomadhya rekhiya vyas (equatorial diameter) ≈ 12,756 km > dhruviya vyas ≈ 12,714 km. Kendra tak ki ausat doori (radius) ≈ 6,371 km.

2.2 Akshansh (Latitude — अक्षांश) aur Deshantar (Longitude — देशांतर)

Akshansh (Latitude)	Deshantar (Longitude)
East-West chalne wali kaalpanik vritt (circles), jo Bhoomadhya rekha (Equator, 0°) se uttar/dakshin ki kon-doori batati hain.	North pole se South pole tak jaane wali ardh-vritt (semi-circles), jo Prime Meridian (0°, Greenwich, London) se poorv/pashchim ki kon-doori batati hain.
Sab samanantar (parallel) — "Parallels of latitude". Equator sabse bada vritt (Great circle); dhruv par bindu matra.	Sab barabar lambai ki; dhruvon par mil jaati hain. Kul 360 (180° E + 180° W).
1° akshansh ≈ 111 km (lagbhag sthir).	Do deshantar ke beech doori equator par sabse zyada (~111 km), dhruv par shoonya.
Kaam: jalvayu/taapmaan kshetra (Torrid, Temperate, Frigid zones).	Kaam: samay (time) nikalna.

Mahatvapurn akshansh	Maan	Note
Bhoomadhya Rekha (Equator / विषुवत रेखा)	0°	Prithvi ko uttari-dakshini golardh me baant ti hai
Karka Rekha (Tropic of Cancer)	23½° N	India ke 8 rajyon se: Gujarat, Rajasthan, MP, Chhattisgarh, Jharkhand, West Bengal, Tripura, Mizoram
Makar Rekha (Tropic of Capricorn)	23½° S	Limpopo nadi ise do baar kaat ti hai (Africa)
Arctic Circle (उत्तर ध्रुव वृत्त)	66½° N	—
Antarctic Circle (दक्षिण ध्रुव वृत्त)	66½° S	—

Ushna Kaṭibandh (Torrid Zone): dono tropics ke beech — yahan saal me kabhi na kabhi dopahar ka suraj bilkul sir ke upar (seedhi kiranein) hota hai → sabse garam.
Shitoshna (Temperate): 23½° se 66½° (dono golardh). Shit (Frigid): 66½° se dhruv tak.

2.3 Samay (Time) — Deshantar se

Prithvi 24 ghante me 360° ghoomti hai → 15° = 1 ghanta, 1° = 4 minute.
Prithvi pashchim se poorv (West → East) ghoomti hai → poorv (east) me samay aage (pehle suryoday).
Greenwich Mean Time (GMT) — 0° deshantar ka samay.
Indian Standard Time (IST): 82°30′ E deshantar (Mirzapur, UP ke paas se) ka samay = GMT + 5:30 ghante (82.5 × 4 = 330 min). Yeh deshantar 5 rajyon se guzarta hai: UP, MP, Chhattisgarh, Odisha, Andhra Pradesh.
India ka poorv-pashchim vistaar ≈ 30° deshantar → Arunachal aur Gujarat ke sthaniya samay me ≈ 2 ghante ka antar.
International Date Line (अंतर्राष्ट्रीय तिथि रेखा): ~180° deshantar; Bering Strait/Pacific me zig-zag. Pashchim ki or paar karne par 1 din jodte hain, poorv ki or paar karne par 1 din ghatate hain.

2.4 Prithvi ki gatiyan (Motions)

Ghoornan (Rotation — घूर्णन)	Parikraman (Revolution — परिक्रमण)
Apni dhuri (axis) par West→East ghoomna	Sun ke chaaron or deergh-vrittakar (elliptical) kaksha me ghoomna
Samay ≈ 24 ghante (sidereal day 23 h 56 m 4 s)	Samay ≈ 365¼ din → har 4 saal me Leap Year (February 29 din)
Parinaam: din-raat, samay ka antar, hawaon/dharaon ka mudna (Coriolis)	Parinaam: ritu parivartan (seasons) + din-raat ki lambai me antar (dhuri ke jhukav ke saath)

Dhuri ka jhukav: Prithvi ki dhuri apne kakshiya tal (orbital plane) se 66½° ka kon banati hai (yaani lamb se 23½° jhuki).
Upsour (Perihelion — उपसौर): Sun se sabse kam doori (~3 January). Apsour (Aphelion — अपसौर): sabse zyada doori (~4 July). Trap: January me Prithvi Sun ke sabse paas hoti hai, phir bhi India me sardi — kyunki ritu jhukav se banti hai, doori se nahi.

Tithi	Ghatna	Uttari golardh me asar
21 June	Kark Sankranti / Summer Solstice — Suraj Karka rekha par seedha	Sabse lamba din, sabse chhoti raat
22 December	Makar Sankranti (khagoliya) / Winter Solstice — Suraj Makar rekha par seedha	Sabse chhota din, sabse lambi raat
21 March & 23 September	Equinox (विषुव) — Suraj Bhoomadhya rekha par seedha	Poori Prithvi par din = raat

2.5 Grahan (Eclipse)

Surya Grahan (Solar Eclipse)	Chandra Grahan (Lunar Eclipse)
Sun — Moon (beech me) — Earth. Chand ki chhaaya Prithvi par.	Sun — Earth (beech me) — Moon. Prithvi ki chhaaya Chand par.
Sirf Amavasya (New Moon) ko sambhav	Sirf Purnima (Full Moon) ko sambhav
Prakar: Poorn (total), Aanshik (partial), Valayakar (Annular — "Ring of Fire") jab chand door ho aur chhota dikhe	Poorn chandra grahan me chand laal-taambai dikhta hai ("Blood Moon")

Har amavasya/purnima ko grahan kyon nahi? — Chand ki kaksha Prithvi ki kaksha se lagbhag 5° jhuki hai; teenon ek seedhi rekha me kabhi-kabhi hi aate hain.

⚠️ Exam Traps:

IST meridian 82°30′E Mirzapur (UP) ke paas; yeh 5 rajyon se guzarta hai — Karka rekha 8 rajyon se. Dono me MP common hai.
Surya grahan = Chand beech me (Amavasya). Chandra grahan = Prithvi beech me (Purnima).
Equator ke paas garmi zyada kyon? — Suraj ki kiranein lagbhag lamb-vat (seedhi) padti hain → kam kshetra par zyada urja.
1° deshantar = 4 minute (akshansh se samay nahi nikalta).

🎯 Official PYQ:

MPESB SI Prelims 2025 — 21 Jan 2026, Shift 2

Why are places near the Equator warmer than those near the poles?भूमध्य रेखा के पास की जगहें ध्रुवों के पास की जगहों से ज़्यादा गर्म क्यों होती हैं?

(1) Equator par adhik varsha hoti hai

(2) Equator par Sun ki kiranein lagbhag lambvat (perpendicular) padti hain

(3) Dhruvon par adhik parvat hain

(4) Equator par vayumandal mota hai

सही उत्तर: (2) — Seedhi kiranein kam kshetra par kendrit hoti hain aur vayumandal me kam doori tay karti hain, isliye adhik garmi. Dhruvon par kiranein tirchhi padti hain.

🌋 3. पृथ्वी की आंतरिक संरचना, चट्टानें, भूकंप-ज्वालामुखी, स्थलाकृतियाँ (9 min read)

3.1 Prithvi ki andaruni parten (Interior of the Earth)

Prithvi ke andar seedhe dekhna sambhav nahi — jaankari mukhyatah bhookampiya tarangon (seismic waves) ke vyavhar se milti hai.

Parat	Gehrai / Tathya
Bhu-parpati (Crust — भूपर्पटी)	Sabse bahari, patli parat. Mahasagariya crust ~5 km, mahadwipiya crust ~30 km (bade parvaton ke neeche 70 km tak). Mahadwipiya = SiAl (Silica + Aluminium); mahasagariya = SiMa (Silica + Magnesium).
Mantle (प्रावार)	Crust ke neeche se ~2,900 km tak. Upari mantle ka kamzor hissa — Asthenosphere (दुर्बलतामंडल) — magma ka mukhya srot. Crust + upari thos mantle = Lithosphere (स्थलमंडल).
Kroḍ (Core — क्रोड)	2,900 km se kendra (~6,371 km) tak. Mukhyatah Nickel + Iron (NiFe). Bahari core — tarl (liquid), aantarik core — thos (solid).

Asambaddhata (Discontinuities): Crust–Mantle ke beech Mohorovičić (Moho); Mantle–Core ke beech Gutenberg (~2,900 km); bahari–aantarik core ke beech Lehmann.
Bhookampiya tarangein: P-waves (Primary) — sabse tez, longitudinal, thos + drav + gas sab me chalti hain. S-waves (Secondary) — transverse, sirf thos me → bahari core me S-waves nahi pahunchti → isi se pata chala ki bahari core drav hai (S-wave shadow zone). Surface/L-waves — sabse dheemi par sabse vinashkari.

3.2 Chattanein (Rocks — शैल)

Prakar	Kaise banti hain	Udaharan
Aagneya (Igneous — आग्नेय) — "Prathamik chattan"	Magma/lava ke thanda hokar jamne se. Andar dheere jamne par antarvedhi (intrusive/plutonic) — bade crystals; satah par jaldi jamne par bahirvedhi (extrusive/volcanic).	Granite (intrusive), Basalt (extrusive — Deccan Trap)
Avsadi (Sedimentary — अवसादी) — "Parat-dar chattan"	Avsad (sediments) ki parton (strata) ke dabne se. Jeevashm (fossils) inhi me milte hain. Prithvi ki satah ka ~75% bhaag inse dhaka.	Sandstone (बलुआ पत्थर), Shale, Limestone (चूना पत्थर), Koyla, Petroleum yahin milta hai
Kayantarit (Metamorphic — कायांतरित)	Pehle se bani chattan par bahut adhik daab + taap se roop badalna	Limestone → Marble; Sandstone → Quartzite; Shale → Slate; Granite → Gneiss; Coal → Graphite

Shail chakra (Rock cycle): ek prakar ki chattan doosre prakar me badalti rehti hai — koi bhi chattan sthayi nahi.

3.3 Plate Tectonics (प्लेट विवर्तनिकी)

Mahadwipiya visthapan (Continental Drift) — Alfred Wegener (1912): sab mahadweep pehle ek the — Pangaea; chaaron or mahasagar — Panthalassa. Pangaea do bhaag me toota: uttar me Laurasia, dakshin me Gondwanaland (India isi ka hissa tha).
Lithosphere badi-chhoti plates me banta hai jo asthenosphere par dheere khisakti hain. 7 badi plates: Pacific, North American, South American, Eurasian, African, Indo-Australian, Antarctic.

Plate seema (Boundary)	Kya hota hai	Udaharan
Apsari (Divergent / Constructive — रचनात्मक)	Plates door jaati hain; magma upar aakar nayi crust banata hai	Mid-Atlantic Ridge
Abhisari (Convergent / Destructive — विनाशात्मक)	Plates takrati hain; ek doosri ke neeche dhasti (subduction); valit parvat, trench, jwalamukhi, bhookamp	Himalaya (Indian + Eurasian plate takkar; beech ka Tethys sagar), Andes
Rupantar (Transform / Conservative — संरक्षी)	Plates ek doosre ke bagal se sarakti hain; crust na banti na nasht hoti	San Andreas Fault (California)

3.4 Bhookamp (Earthquake — भूकंप)

Udgam kendra (Focus / Hypocentre): jahan andar urja mukt hoti hai. Adhikendra (Epicentre — अधिकेंद्र): focus ke theek upar satah ka bindu — yahan sabse zyada nuksan.
Mapan: Seismograph (yantra); Richter scale = magnitude (urja), logarithmic (1 ank badhne par ~10 guna ayam); Mercalli scale = intensity (nuksan), I–XII.
Tsunami (Japanese shabd — "harbour wave"): samudra tal ke bhookamp/jwalamukhi se uthi vishal lehrein (e.g. 26 Dec 2004 Hind Mahasagar tsunami).
India ke seismic zones: BIS map IS 1893 (Part 1): 2016 ke anusaar 4 zones — II, III, IV, V (Zone V sabse khatarnak: poora North-East, J&K ke hisse, Kutch, Andaman-Nicobar aadi). Trap: Nov 2025 me BIS ne naya map (Zone VI ke saath) notify kiya tha, par 3 March 2026 ko use wapas le liya gaya; 2016 wala 4-zone system hi laagu hai (Sep 2026 tak).

3.5 Jwalamukhi (Volcano — ज्वालामुखी)

Magma satah par aaye to lava kehlata hai. Mukh = crater; bada dhansa crater = caldera.
Pacific "Ring of Fire" (अग्नि वलय): duniya ke adhiktar sakriya jwalamukhi aur bhookamp Pacific mahasagar ke kinaron par.
Prakar (sakriyata se): Sakriya (active) — jaise Etna (Sicily), Stromboli — "Lighthouse of the Mediterranean", Mauna Loa (Hawaii — vishal shield volcano); Prasupt (dormant); Mrit/Shant (extinct).
India ka ekmatra sakriya jwalamukhi — Barren Island (Andaman Sagar). Narcondam (Andaman) — prasupt maana jata hai.
Deccan Trap: ~6.5 crore saal pehle darar (fissure) udgaar se basalt lava phaila → isi se kaali mitti bani (MP ka Malwa bhi isi me).
Jwalamukhi se bane parvat: Kilimanjaro (Africa ka sabse ooncha), Fujiyama (Japan).

3.6 Mukhya sthalakritiyan (Landforms) — kaun kis se banta hai

Karak (Agent)	Apardan (erosion) se	Nikshepan (deposition) se
Nadi (River)	V-aakar ghati, gorge, canyon (Grand Canyon — Colorado nadi), jalprapat (waterfall)	Meander (vissarp), Oxbow lake (गोखुर झील), baadh maidan (flood plain), taṭbandh (levee), delta
Himnad (Glacier)	U-aakar ghati, cirque, fjord (Norway)	Moraine (हिमोढ़)
Pawan (Wind) — marusthal	Mushroom/Chhatrak rock, yardang	Baalu ke teele (sand dunes) — Barchan = ardh-chandrakar (crescent); Seif = lambvat/longitudinal; Loess (China — mahin mitti)
Samudri lehrein	Cliff, sea cave, arch, stack	Beach, spit, bar, lagoon
Bhoomigat jal (chuna-pattar / Karst)	Sinkhole, gufaayein	Stalactite (chhat se latakta), Stalagmite (farsh se upar uthta)

Parvat ke prakar: Valit (Fold) — Himalaya, Alps, Andes, Rockies (navin); Aravalli, Appalachian, Ural (prachin). Bhransh/Block (Block) — do bhransh (fault) ke beech utha hissa (Europe: Vosges, Black Forest); neeche dhansa hissa = Rift valley (भ्रंश घाटी) — Narmada aur Tapi rift valleys me behti hain. Jwalamukhi — Kilimanjaro, Fujiyama. Avshisht (Residual) — ghis kar bache purane parvat (Aravalli).
Pathar (Plateau): Tibet — sabse ooncha pathar ("Roof of the World"); Deccan pathar (India); Chhota Nagpur (khanij bhandar).

⚠️ Exam Traps:

S-waves drav me nahi chalti — isliye bahari core drav maana jata hai; aantarik core thos hai.
Richter = magnitude (urja); Mercalli = intensity (nuksan).
Fossils + koyla + petroleum = avsadi chattan. Marble = kayantarit (limestone se).
Barchan = ardh-chandrakar teela (Thar me bhi bahut). Seif = lamba (longitudinal).
Stalactite = Top (chhat) se latakta; Stalagmite = neeche (ground) se.

☁️ 4. वायुमंडल एवं ऊष्मा (Atmosphere, Insolation & Heat Transfer) (9 min read) — 10 PYQs!

4.1 Vayumandal ki sanrachna (Composition)

Gas	% (aayatan/volume)	Exam point
Nitrogen (N₂)	~78%	Sabse adhik
Oxygen (O₂)	~21%	Jeevan ke liye
Argon (Ar)	~0.93%	Sabse adhik akriya (inert) gas
Carbon dioxide (CO₂)	~0.04%	Aane wale suryaprakash ke liye paardarshi, par jaane wale parthiv vikiran (terrestrial radiation) ke liye apaardarshi — yahi use absorb karti hai → greenhouse effect. Fossil fuel jalne se lagatar badh rahi hai.
Ozone (O₃)	Bahut kam	Satah se 10–50 km ke beech; suraj ki parabaingani (UV) kirnon ko absorb karti hai

Jalvashp (water vapour) aur dhool-kan zyadatar neeche ki parat (troposphere) me — isiliye baadal, varsha, mausam wahin.

4.2 Vayumandal ki parten — taapmaan ke aadhar par 5 parten (NCERT)

Parat	Oonchai	Mukhya tathya
1. Kshobhmandal (Troposphere)	Ausat 13 km (dhruv ~8 km, equator ~18 km)	Sabse neeche; saare mausami badlav yahin (baadal, varsha, toofan). Oonchai ke saath taapmaan girta hai — 1°C prati 165 m. Equator par sabse moti kyonki tez sanvahan dharayein garmi ko oonchai tak le jaati hain.
Kshobhsiima (Tropopause)	—	Troposphere aur stratosphere ko alag karne wala kshetra. Taapmaan lagbhag sthir: equator par ~ −80°C, dhruvon par ~ −45°C.
2. Samtapmandal (Stratosphere)	50 km tak	Ozone parat — UV absorb. Shant, badal-rahit → jet vimaan iske nichle hisse me udte hain. Oonchai ke saath taapmaan badhta hai.
3. Madhyamandal (Mesosphere)	80 km tak	Taapmaan phir girta hai — 80 km par −100°C tak (sabse thandi parat). Ulkayein yahin jalti hain. Upari seema = Mesopause.

4.3 Suryatap (Insolation), Parthiv Vikiran aur Ushma Bajat

Suryatap / Insolation (सूर्यातप): Prithvi dwara Sun se prapt urja (laghu tarangon — short waves ke roop me).
Parthiv vikiran (Terrestrial radiation — स्थलीय विकिरण): garam Prithvi deergh tarangon (long waves) me urja chhodti hai → isi se vayumandal neeche se garam hota hai (seedhe suryaprakash se nahi). CO₂ aur greenhouse gases ise absorb karti hain.
Albedo (एल्बिडो / परावर्तन गुणांक): kisi satah dwara paravartit prakash ka anupaat. Barf ka albedo sabse zyada. Prithvi ka ausat albedo ~35 units (100 me se) — NCERT heat budget.
Ushma bajat (Heat budget): Prithvi jitni urja leti hai utni hi wapas chhod deti hai — isliye Prithvi na lagatar garam hoti na thandi.

4.4 Ushma sthanantaran ke 4 tareeke (Heat transfer) — PYQ favourite

Prakriya	Matlab	Vayumandal me udaharan
Chaalan (Conduction — चालन)	Asamaan taapmaan wali do vastuon ke seedhe samparka (direct contact) se ushma ka jaana	Garam zameen se usse sati hawa ki nichli parat garam hoti hai
Sanvahan (Convection — संवहन)	Garam hawa oopar (vertical) uthti hai aur ushma ko oopar le jaati hai	Troposphere tak seemit; equator par dopahar ki sanvahani varsha
Abhivahan (Advection — अभिवहन/प्रवहन)	Hawa ki kshaitij (horizontal) gati se ushma ka sthanantaran	Madhya akshanshon me din-raat ke taapmaan badlav; North India ki "Loo" isi ka parinaam (NCERT)
Vikiran (Radiation — विकिरण)	Bina madhyam ke tarangon dwara	Sun → Prithvi (insolation); Prithvi → vayumandal (terrestrial radiation)

Taapmaan vyutkraman (Temperature Inversion): saamanya ulta — oonchai ke saath taapmaan badhe; lambi saaf sardi ki raaton me ghaatiyon me (kohra/smog).
Greenhouse gases: CO₂, Methane (CH₄), Nitrous oxide, CFCs, jalvashp. Ozone kshay (depletion) ka mukhya kaaran — CFCs; Montreal Protocol (1987).

⚠️ Exam Traps:

Troposphere aur stratosphere ke beech = Tropopause (Stratopause/Mesopause nahi).
Taapmaan ke aadhar par parten = 5 (NCERT: Tropo, Strato, Meso, Thermo, Exo). Ionosphere, thermosphere ka hi hissa hai.
Ozone = 10–50 km, UV absorb karti hai (produce nahi). Ozone layer stratosphere me.
Vertical = Convection; Horizontal = Advection; Direct contact = Conduction.
Parthiv vikiran ka bada hissa CO₂ absorb karti hai (N₂/O₂ nahi).
Tropopause ka taapmaan equator par −80°C (dhruv par −45°C) — equator par zyada thanda kyonki wahan tropopause zyada oonchai (18 km) par hai.

🌀 5. वायुदाब, पवनें एवं चक्रवात (Pressure Belts, Winds & Cyclones) (9 min read) — 6 PYQs

5.1 Vayudab (Air Pressure) ke basics

Hawa hamesha uchch daab (High) se nimn daab (Low) ki or bahti hai. Mapak yantra — Barometer; pawan gati — Anemometer; disha — Wind vane; aardrata — Hygrometer.
Samdaab rekha (Isobar): naksha par barabar vayudab wale sthanon ko jodne wali rekha. Isobars paas-paas = daab pravanata (pressure gradient) tez = hawa tez; door-door = hawa dheemi.
Coriolis bal (कोरिओलिस बल): Prithvi ke ghoornan se hawa mudti hai — uttari golardh me daayein (right), dakshini golardh me baayein (left) (Ferrel's law). Equator par Coriolis shoonya, dhruvon par adhiktam.
Bhoovikshepi pawan (Geostrophic wind — भूविक्षेपी पवन): upari vayumandal me (satah ke gharshan se door) jab daab pravanata bal aur Coriolis bal santulit ho jaate hain, to hawa isobars ke samanantar (parallel) bahti hai.

5.2 Vishwa ke daab kaṭibandh (Pressure Belts) aur sthayi pawanein (Planetary winds)

Daab patti	Akshansh	Khaas baat
Bhoomadhya rekhiya nimn daab	0° ke aas-paas	Doldrums (शांत पेटी) — shaant hawa. Yahan dono golardh ki trade winds milti hain → ITCZ
Upoushna uchch daab (Subtropical High)	~30° N/S	Horse latitudes; duniya ke bade garam marusthal isi ke aas-paas (Sahara, Thar, Kalahari...)
Upadhruviya nimn daab (Subpolar Low)	~60° N/S	—
Dhruviya uchch daab (Polar High)	90° N/S	—

Pawan	Kahan se kahan	Disha
Vyaparik pawan (Trade winds)	30° uchch daab → equator nimn daab	Uttari golardh me North-East trades, dakshini golardh me South-East trades
Pachhua pawan (Westerlies)	30° → 60°	Pashchim se poorv. Dakshini golardh me khule samudra par bahut tez: Roaring Forties (40°), Furious Fifties (50°), Shrieking/Screaming Sixties (60°)
Dhruviya poorvi pawan (Polar easterlies)	Dhruv → 60°	Poorv se, thandi

ITCZ (Inter Tropical Convergence Zone — अंतर-उष्णकटिबंधीय अभिसरण क्षेत्र): equator ke paas ka nimn daab kshetra jahan trade winds milti (converge) hain; hawa oopar uthti hai → baadal-varsha. Garmiyon me yeh uttar khisak kar North India par aa jaata hai (monsoon trough) — Indian monsoon se juda.
Jet streams: upari troposphere me tez, sankari pawan dharayein. Sardi me Subtropical Westerly Jet Himalaya ke dakshin → Western Disturbances (पश्चिमी विक्षोभ) laata hai (North-West India me sardi ki varsha — rabi ke liye laabh). Garmi me Tropical Easterly Jet — monsoon se juda.

Mistral / Bora	France (Rhone ghati) / Adriatic tat	Thandi

5.4 Chakravat (Cyclones — चक्रवात)

Chakravat = kendra me nimn daab; hawa baahar se andar ki or ghoomti hai — uttari golardh me anticlockwise (vaamavart), dakshini me clockwise. Pratichakravat (Anticyclone) = kendra me uchch daab, saaf mausam.
Ushna-kaṭibandhiya chakravat banne ki sharten: garam samudra satah (~27°C se zyada), Coriolis bal (isliye equator ke bilkul paas nahi bante), kam vertical wind shear, pehle se maujood kamzor nimn daab.
Kendra me shaant, baadal-rahit bhaag — Aankh (Eye); uske chaaron or sabse tez hawa-varsha — eye wall.
Zameen par aate hi kamzor kyon? — samudra se nami (moisture/urja) ki aapoorti band ho jaati hai + zameen ka gharshan.
India me Bay of Bengal me Arabian Sea se zyada chakravat; mukhya mausam: pre-monsoon (Apr–May) aur post-monsoon (Oct–Dec).
