Question

Quizplus · Accepted Answer

Alluvial fans are deposits formed by flowing water in a stream or river as it exits a mountainous region and enters a flatter plain or valley. Over time, multiple alluvial fans may merge together, forming a continuous apron of sediment called a bajada. Wadis are dry streambeds that may have water only during flash floods. Talus aprons are piles of rock debris that accumulate at the base of slopes. Playas are dry, flat lake beds that form in arid regions.
