Alluvial fans are formed as a ____ flows down from steep mountain slopes and deposits sediments when it reaches a gentle slope.
stream
Alluvial fans form when a fast-flowing mountain stream, carrying large amounts of sediment, suddenly slows down as it exits a steep valley and reaches a flatter plain.
This sudden loss of speed causes the stream to deposit its sediment load in a distinctive fan-shaped pattern spreading outward from the point where the slope changes.
Lava flow, wind, and ocean currents are different geological or atmospheric agents that do not form this particular fan-shaped stream-deposited landform.
