Namaste dosto! Aaj hum baat karenge hamari dharti yaani Earth ke baare mein aur samjhenge ki ise maps aur science ke zariye kaise dekha jata hai. Chaliye shuru karte hain hamara safar! Map hamari earth’s surface ki ek drawing ya representation hoti hai. Ye teen tarah ke hote hain: Physical Maps: Inme aapko natural resources jaise pahad (Mountains), samundar (Oceans) aur plateaus dikhai dete hain. Political Maps: Ye shehron (Cities), towns, states aur countries ki boundaries batate hain. Thematic Maps: Ye kisi specific jankari ke liye hote hain, jaise ki barish ya sadkon ka data. Directions (Dishaen): Cardinal: North, South, East, West. Intermediate: Inke beech ki dishaen—N.E (North-East), S.E (South-East), S.W (South-West) aur N.W (North-West). Hamari dharti char hisson mein banti hui hai: Lithosphere: Ye pathrila (Stone) solid portion hai jahan hum rehte hain. Hydrosphere: Dharti ka 71% hissa pani se dhaka hai. Atmosphere: Wo gaseous layer jo dharti ko charon taraf se ghere hue hai. Biosphere: Jahan land, water aur air milte hain, wahi life possible hai. Duniya mein alag-alag continents hain, chaliye unki khasiyat dekhte hain: Continent Area (Million sq km) Key Features Asia 44.58 km² Ural mountains ise Europe se alag karte hain. Africa 30.37 km² Yahan Sahara Desert (Largest hot desert) aur Nile River (Longest) hai. North America 24.71 km² Panama Strip ise South America se jodti hai. South America 17.84 km² Amazon River (Largest) aur Andes (Longest range) yahi hain.
