MOUNTAINS break into foot slope plains of low gradient.This stream spreads as a broad low to a high cone-shaped deposit called an alluvial fan that appears as a series of CONTINUOUS fans.Such fans appear THROUGHOUT the Himalayan foothills in the north Indian plains.‘V’-shaped valleys-Valleys start as small and narrow rills, these rills will progressively develop into long and wide gullies.The V-shaped valley is created due to vertical erosion of the river in its upper course in the mountainous area.Deltas - A river DELTA is a low-lying plain that occurs at the mouth of a river near where it flows into an ocean or another larger body of water.These are formed near the coastal areas.Ox-bow LAKES - At the lower reaches of the rivers, when rivers have larger sediment than the volume of water, it starts meandering.Sometimes, in absence of enough water, some portions of meandering get separated, and that creates ox-bow lakes.
