Answer» Moving streams are so powerful that it can wear away soil rocks. Rocks on higher land get eroded due to the strong current of the streams and they in turn get carried away into the sea. Silt too is brought down from the mountain top from where the streams originate. Most of the sand in the river is silt carried by the streams and the weather material from inland rocks transported by the streams. The moving of soil and rock with the stream, termed as erosion can be summed up as the cause of sand formation in a river.
