In a valley, a plain is enclosed on two sides, but in other cases a plain may be delineated by a complete or partial ring of hills, by mountains, or by cliffs.

Plains are one of the major landforms on earth, where they are present on all continents, and would cover more than one-third of the world's land area.

Coastal plains would mostly rise from sea level until they run into elevated features such as mountains or plateaus.
