Answer 1

Answer:

Rivers have a major influence on the rocks and soils over which they flow. ... When a river overflows its banks, the nearby areas get flooded. During the flood, a thin layer of fine soil and silt gets deposited over the land, thereby forming rich alluvial soil which is highly fertile and nutrient-dense for the plants.
