Answer 2

a. Only A is correct

A triangle-shaped deposit of gravel, sand, and even smaller bits of sediment, such as silt, is known as an alluvial fan. Alluvium is the name given to this type of material.

Explanation:

• Landforms generated by the deposition of material carried by flowing water are referred to as alluvial fans and deltas. In general, alluvial fans form at higher elevations, like as mountains, whereas deltas form near the coast.
• Alluvial fans emerge when flowing water collides with mountains, hills, or canyon walls. Sand and other particles are gathered up by a stream as it travels down a hill, and this is known as alluvium.
• The flowing water transports alluvium to a level plain, where the stream diverges from its original path to expand out.
