What Are Plains? A Comfortisive Definition
In geomorphophologiy, a plain is defined a broad area of relatively flat land with local relief. Unlike plateaus, plains lack signiant elevation thee aroundinary ounding terrain; mott lie at low altimedes, though some can ce found at higher elevations. Plains are typically underlain by sedimentary strata or thick alluvial deposits, and they often exhibit entlllllopes thathan a few ene.

Geological Processes in Plain Formation

Te relative importance of each process varies dependiing on regional geology, climate, and tectonic setting.
