Question

Alluvial fans form mostly in blank regions

A.Arid
B.Coastal
C.Polar
D. Tropical

Answer 1

Alluvial fans primarily form in **A. Arid** regions. These landforms are typically created in areas where extreme slope changes occur, such as where a river flows from mountainous terrain into a flatter area, allowing sediment to spread out and deposit. Arid environments often have the right conditions for these processes to take place, especially where there is variability in water flow.
