Question

Quizplus · Accepted Answer

A pediment is a gently sloping erosion surface that forms at the base of a mountain range as a result of tectonic uplift. It is typically found in desert environments and can be quite expansive. A bajada is also a broad, sloping surface at the base of mountains in deserts, but it is made up of a series of alluvial fans rather than being one continuous surface. A butte is a isolated hill with steep sides and a flat top, while an alluvial fan is a fan-shaped deposit of sediment that forms when a stream's velocity decreases as it emerges from a narrow canyon onto a wide plain.
