The correct option is 1, 2 and 3
Explanation
Plateaus are elevated flatlands that often serve as storehouses of minerals. Their resource potential depends largely on their geological formation and age.- Pair 1 is correctly matched: The African Plateau is famous for its rich mineral deposits. Specifically, the southern and eastern parts of the plateau are globally significant sources of gold and diamonds.
- Pair 2 is correctly matched: The Chhotanagpur Plateau in India is often referred to as the mineral heartland of the country. It contains huge reserves of iron ore, coal, manganese, and mica.
- Pair 3 is correctly matched: Lava plateaus, such as the Deccan Traps in India, are formed by the solidification of basaltic lava. Over time, the weathering of these volcanic rocks produces fertile black soil (Regur), which is highly suitable for cultivation, particularly for cotton.
Key Takeaway: Plateaus are economically significant landforms; ancient shield plateaus are typically rich in metallic minerals like iron and gold, while volcanic plateaus provide fertile soil for agriculture.
