How is the effect of young mountain region seen in Himalayan rivers?

Answer and explanation

Correct answer: As strong erosion high sediment and deep valleys

The direct answer is A: strong erosion, high sediment and deep valleys. The Himalayas are young fold mountains, so their slopes are high, steep and still being actively shaped by erosion. Step by step: young, steep mountains provide a large height difference and steep gradients → rivers gain speed and energy → they cut their beds and valley sides strongly → rock and soil are removed and carried downstream as sediment → deep gorges and valleys, high sediment load and intense erosion are observed. Option A is correct because it includes the connected effects of young relief: strong erosion, sediment transport and deep valleys. Option B is wrong because Himalayan rivers generally have substantial flow, even though seasonal discharge can vary; complete dryness is not the characteristic effect. Option C is wrong because tidal waves are coastal influences, not the main expression of young mountain relief. Option D is wrong because coral formation is a marine biological process and is unrelated to mountain river erosion. Remember the chain: young and steep mountains → fast rivers → strong erosion → deep valleys and much sediment.
