Answers
Answer:
It consists of silt, sand, clay, and gravel, as well as much organic matter. Alluvial deposits are usually most extensive in the lower part of a river's course, forming floodplains and deltas, but they may form at any point where the river overflows its banks or where the flow of a river is checked.
Answer:
An alluvial fan is an accumulation of sediments shaped like a section of a shallow cone,[1] with its apex at a point source of sediments, such as a narrow canyon emerging from an escarpment.[2] They are characteristic of mountainous terrain in arid to semiarid climates,[3][4] but are also found in more humid environments subject to intense rainfall[1] and in areas of modern glaciation.[4] They range in area from less than 1 square kilometre (0.39 sq mi)[4][5] to almost 20,000 square kilometres (7,700 sq mi).[6]
