उत्तर
- The force of flowing streams is so great that they may destroy rocks and soil.
- The powerful stream currents erode rocks on higher ground, which are then swept away into the sea.
- Additionally, silt is carried down from the mountain top where the streams begin.
- The majority of the sand in the river is silt that the streams carry, together with weather material from inland rocks.
- Sand formation in a river is caused by erosion, which is the movement of rock and soil with the stream.
