Bench (geology)

（重定向自Benchland）

Hypothetical cross-section of a river valley showing different types of benches. They include structural benches (sb) formed by the differential erosion of shale beds overlying limestone beds. Also, they include benches in the form of narrow strath terraces (st), fill terraces (ft), and cut terraces (ct) underlain by fluvial sediments.

In geomorphology, geography and geology, a bench or benchland is a long, relatively narrow strip of relatively level or gently inclined land that is bounded by distinctly steeper slopes above and below it. Benches can be of different origins and created by very different geomorphic processes.
