Hum Geography Kyun Padhte Hain?
- Hum dharti par rehte hain aur hamari life surroundings se affect hoti hai.
- Hum resources ke liye nature par depend karte hain.
- Example: Pehle ki societies "natural means of subsistence" (edible plants/animals) par depend thi.
- GIS aur computer cartography jaisi techniques humein desh ke vikas (national development) mein madad karti hain.
Geography ke 3 Main Sawal
Geography in teen sawalo ka jawab dhundti hai:
- What? - Earth par kaunse patterns paye jate hain?
- Where? - Features kahan distributed hain?
- Why? - Unke beech ka Causal Relationship (karan) kya hai?
Padhne ke Do Approaches
1. Systematic Approach: Alexander Von Humboldt ne diya. Isme ek phenomenon (jaise vegetation) ko poori duniya ke level par study karte hain.
2. Regional Approach: Karl Ritter ne diya. Isme duniya ko regions mein baant kar study karte hain.
Branches of Geography
A. Physical Geo: Geomorphology (landforms), Climatology (weather), Hydrology (water), Soil Geography (pedogenesis).
B. Human Geo: Social/Cultural, Population, Economic, Historical, aur Political.
C. Biogeography: Plant aur Animal geography, Ecology, aur Environmental issues.
Physical Geography ki Importance
Isme Lithosphere, Atmosphere, Hydrosphere aur Biosphere ki study hoti hai.
- Example: Plains agriculture ke liye hain, plateaus minerals aur forests dete hain.
- Example: Oceans storehouse hain minerals aur sea-food ke.
Inhe samajhna Sustainable Development ke liye bahut zaroori hai.
--- EXERCISE SOLUTIONS ---
1. MCQs: (i) b - Eratosthenese, (ii) c - Plain, (iii) d (1C, 2A, 3D, 4B), (iv) a - Why, (v) d - History.
2. Short Answers (30 Words):
- Shape of Earth: Yeh ek Orange jaisa hai (Equator par bulging, Poles par flat).
- Van Mahotsava: Hum ped lagate hain taaki Ecological Balance bana rahe aur oxygen mile.
- Biosphere: Yeh wo sphere hai jahan hathi, hiran aur ghas rehte hain.
--- PROJECT WORK: FORESTS ---
Example: India mein Evergreen aur Mangrove forests ka distribution alag hai. Inka economic use timber aur medicine mein hota hai.
Conservation: Chipko Movement (Rajasthan aur Uttaranchal) ne forest bachane ki misal di.
