<h2 id="description">Description</h2> <p>A plain or flatland is a flat expanse of land with a layer of grass that generally does not change much in <a href="/facts/Elevation/h2d0u9nd">elevation</a>, and is primarily treeless. Plains occur as <a href="/facts/Lowland/WFatkmW0">lowlands</a> along <a href="/facts/Valley/gKmvE6L1">valleys</a> or at the base of <a href="/facts/Mountain/wboT5GJc">mountains</a>, as <a href="/facts/Coastal_plain/5lx4pTgr">coastal plains</a>, and as <a href="/facts/Plateau/R9ugUKzQ">plateaus</a> or <a href="/facts/Highland/U5sXdWdm">uplands</a>.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> Plains are one of the major <a href="/facts/Landform/eI0tkDYB">landforms</a> on earth, where they are present on all continents, and cover more than one-third of the world's land area.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p><p>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 <a href="/facts/Cliff/P7tXINep">cliffs</a>.
