Super TET EVS पृथ्वी की आंतरिक संरचना MCQ (Internal Structure of Earth Questions) 2026

Namaste dosto! Super TET 2026 ki taiyari mein aapka swagat hai Unictest par. Aaj hum EVS (Environmental Studies) ke ek behad important topic – पृथ्वी की आंतरिक संरचना (Internal Structure of Earth) par focus karenge. Maine apne teaching career mein dekha hai ki yeh topic students ko aksar mushkil lagta hai, lekin trust me, agar aap isko sahi tareeke se samajh lete hain, toh isse aane wale har question ka answer dena aasan ho jayega. Super TET mein EVS section kaafi scoring hota hai, aur Earth ki internal structure se 2-3 questions aana toh pakka hai. Toh chaliye, shuru karte hain kuch important MCQs ke saath aur saath hi topic ko bhi deeply samjhenge.

Dekhiye, hamari Prithvi sirf upar se hi nahi, andar se bhi kayi paraton (layers) se bani hai, bilkul ek pyaaz ki tarah! Inhi paraton ko samajhna hi Internal Structure of Earth ko padhna hai. Isse humein earthquakes, volcanoes aur plate tectonics jaisi ghatnaon ko samajhne mein madad milti hai. Jo students is chapter ko skip kar dete hain, woh bahut badi galti karte hain, kyunki yeh sirf EVS ka topic nahi, geography ka bhi foundation hai.

पृथ्वी की प्रमुख परतें (Main Layers of the Earth)

Hamari dharti ko mukhyatah teen concentric layers mein divide kiya gaya hai:

• भूपर्पटी (Crust): Yeh sabse upari aur sabse patli parat hai.
• मैंटल (Mantle): Crust ke neeche ki parat, jo Earth ke volume ka lagbhag 84% hai.
• क्रोड (Core): Sabse andar ki parat, jo do hisson mein divided hai – Outer Core aur Inner Core.

भूपर्पटी (Crust) – The Outermost Layer

Crust dharti ki sabse upari solid layer hai. Iski motai (thickness) continents ke neeche 35-70 km tak aur oceans ke neeche 5-10 km tak hoti hai. Yeh mainly do prakar ki hoti hai:

• महाद्वीपीय भूपर्पटी (Continental Crust): Yeh granitic rocks se bani hai, jismein Silica (Si) aur Aluminium (Al) zyada hote hain, isliye ise SIAL bhi kehte hain. Iski density kam hoti hai.
• महासागरीय भूपर्पटी (Oceanic Crust): Yeh basaltic rocks se bani hai, jismein Silica (Si) aur Magnesium (Mg) zyada hote hain, isliye ise SIMA bhi kehte hain. Yeh continental crust se zyada dense hoti hai.

Pichle 5 saal mein maine notice kiya hai ki crust ki composition aur types par based questions Super TET mein aksar pooche jaate hain. Isliye is hisse ko dhyan se padhiye.

मैंटल (Mantle) – The Middle Layer

Crust ke theek neeche Mantle hai, jo lagbhag 2900 km tak faila hua hai. Yeh Earth ke total volume ka 84% aur mass ka 67% banata hai. Mantle mainly silicate rocks se bana hai, jo iron aur magnesium mein rich hote hain. Mantle ko bhi further do parts mein divide kiya ja sakta hai:

• ऊपरी मैंटल (Upper Mantle): Ise Asthenosphere bhi kehte hain. Yeh semi-molten state mein hota hai, jiske upar tectonic plates float karti hain.
• निचली मैंटल (Lower Mantle): Yeh solid state mein hai, lekin high temperature aur pressure ke karan ismein material plastic ki tarah behave karte hain.

क्रोड (Core) – The Innermost Layer

Core Earth ki sabse andar ki parat hai, jiska radius lagbhag 3500 km hai. Yeh mainly Nickel (Ni) aur Iron (Fe) se bana hai, isliye ise NIFE bhi kehte hain. Core do hisson mein divided hai:

• बाह्य क्रोड (Outer Core): Yeh molten state mein hai. Yahan par convection currents generate hote hain, jo Earth ke magnetic field ke liye responsible hain.
• आंतरिक क्रोड (Inner Core): Yeh solid state mein hai, despite extremely high temperatures. Iska karan hai yahan ka exorbitant pressure, jo material ko solid hi rakhta hai.

Ab jab humne basic layers ko samajh liya hai, toh chaliye kuch MCQs solve karte hain. Yaad rakhiye, har question ko dhyan se padhna hai aur fir answer choose karna hai. Ghabrahat mein galat answer mat dena!

Super TET EVS Internal Structure of Earth MCQs - Part 1

Bahut badhiya! Agar aapne in questions ke answers sahi diye hain, toh aapki foundation strong hai. Agar kuch galat hue hain, toh ghabraiye nahi, abhi toh hum seekh hi rahe hain. Yaad rakhiye – har topper bhi ek baar beginner tha. Bas consistency rakhiye aur Unictest ke saath jude rahiye!

Dosto, sirf questions solve karna hi kaafi nahi hai. Super TET jaise competitive exams ko crack karne ke liye ek solid preparation strategy ka hona bahut zaroori hai, especially EVS jaise diverse subject ke liye. Jab main apne students ko guide karta hoon, toh hamesha kehta hoon ki smart work hard work se zyada important hai. Chaliye, dekhte hain ki EVS mein पृथ्वी की आंतरिक संरचना topic ko kaise master kiya ja sakta hai.

Super TET EVS की तैयारी की रणनीति (Preparation Strategy for Super TET EVS)

EVS section mein aapko geography, history, civics, science aur environmental awareness se jude questions milenge. पृथ्वी की आंतरिक संरचना geography ka hissa hai. Iske liye aapko concepts ki clarity bahut zaroori hai. Sirf ratta marne se kaam nahi chalega.

• NCERT Books ka Mahatva: Class 6th to 10th ki NCERT Geography ki books aapki bible hain. Internal Structure of Earth ke basics wahan se clear honge. 2024 ki UPTET exam mein bhi NCERT based questions kaafi aaye the.
• Diagrams aur Flowcharts: Har layer ki composition, depth, temperature aur pressure ko diagrams ya flowcharts ke through padhiye. Jaise, SIAL, SIMA, NIFE terms ko yaad rakhne ke liye mnemonics bana sakte hain.
• Previous Year Papers (PYPs): Pichle 5-7 saal ke Super TET aur anya teaching exams (CTET, UPTET, KVS) ke EVS section ke PYPs zaroor solve karein. Isse aapko questions ka pattern aur important areas samajh aayenge. Maine personally dekha hai ki 40% questions ka pattern repeat hota hai!
• Daily Revision: Jo bhi padha hai, use har din revise karein. Raat ko sone se pehle 10 minutes mein 20 facts revise karo, brain mein permanent ho jayenge.

महत्वपूर्ण विषय और पुस्तकें (Important Topics and Recommended Books)

पृथ्वी की आंतरिक संरचना ke under aapko in topics par special focus karna hai:

• पृथ्वी की परतें और उनकी विशेषताएं (Crust, Mantle, Core - composition, thickness, states).
• प्रमुख असंबद्धताएं (Major Discontinuities - Moho, Gutenberg, Lehmann).
• भूकंपीय तरंगें (Seismic Waves - P, S, L waves aur unka Earth ke andar behaviour).
• पृथ्वी के आंतरिक भाग का तापमान और दबाव (Temperature and Pressure in Earth's interior).
• पृथ्वी की उत्पत्ति और विकास के सिद्धांत (Theories of Earth's origin and evolution - brief overview).

Recommended Books:

• NCERT Geography Books (Class 6-10)
• Lucent's General Knowledge (for quick facts and revision)
• Arihant's Super TET EVS Guide (for exam-specific content)

अध्ययन अनुसूची और समय प्रबंधन (Study Schedule and Time Management)

Ek well-planned study schedule aapki taiyari ko track par rakhta hai. Maine dekha hai ki jo students time management par dhyan dete hain, woh kam samay mein bhi behtar result dete hain.

• Early Morning Study: Subah ka samay naye aur mushkil topics ke liye best hota hai. EVS ke conceptual parts ko subah padhein.
• Slot-based Study: 2-3 ghante ke slots mein padhein. Har slot ke baad 15-20 minute ka break lein. Ek slot mein EVS, doosre mein Math, teesre mein Hindi.
• Weekly Revision: Har weekend par poore hafte jo padha hai, uska comprehensive revision karein. Ismein MCQs solve karna aur mock tests dena shamil hai.
• Mock Tests: Unictest par available mock tests zaroor dein. Isse aapko real exam environment ka experience milega aur apni strengths aur weaknesses pata chalengi.

Ab kuch aur MCQs solve karte hain. Dekhte hain ki aapki taiyari kitni solid hai!
