Why do meanders form more in the plains of Himalayan rivers?

Correct answer: Low slope makes the river slow and winding

The direct answer is A, low slope makes the river slower and more winding. A meander is a large bend in a river channel. In mountains, the slope is steep, so water generally flows rapidly through narrow valleys and is more likely to cut downward. In the plains, the slope becomes gentle. The river loses speed, spreads across a wider floodplain, erodes the outer bank, deposits material on the inner bank, and gradually develops bends. Option A is correct because gentle gradient and lateral erosion encourage meanders. Option B, the sea entering mountains, is not required for meanders. Option C, the river drying completely, would stop flow rather than create active bends. Option D, flowing only along a straight fault line, describes neither normal meandering nor the broad floodplain process. A river can have local controls, but the basic school-level reason is gentle slope and slower flow. Memory cue: plains plus slow flow equals meanders.
