It makes up 29.2% of Earth's surface and includes all <a href="/wiki/Continent" title="Continent">continents</a> and <a href="/wiki/Island" title="Island">islands</a>. Earth's land surface is almost entirely covered by <a href="/wiki/Regolith" title="Regolith">regolith</a>, a layer of <a href="/wiki/Rock_(geology)" title="Rock (geology)">rock</a>, <a href="/wiki/Soil" title="Soil">soil</a>, and <a href="/wiki/Mineral" title="Mineral">minerals</a> that forms the outer part of the <a href="/wiki/Earth%27s_crust" title="Earth's crust">crust</a>. Land plays an important role in Earth's <a href="/wiki/Climate_system" title="Climate system">climate system</a>, being involved in the <a href="/wiki/Carbon_cycle" title="Carbon cycle">carbon cycle</a>, <a href="/wiki/Nitrogen_cycle" title="Nitrogen cycle">nitrogen cycle</a>, and <a href="/wiki/Water_cycle" title="Water cycle">water cycle</a>. One-third of land is covered in trees, another third is used for <a href="/wiki/Agriculture" title="Agriculture">agriculture</a>, and one-tenth is covered in permanent snow and <a href="/wiki/Glacier" title="Glacier">glaciers</a>. The remainder consists of <a href="/wiki/Desert" title="Desert">desert</a>, <a href="/wiki/Savannah" class="mw-redirect" title="Savannah">savannah</a>, and <a href="/wiki/Prairie" title="Prairie">prairie</a>. </p><p>Land <a href="/wiki/Terrain" title="Terrain">terrain</a> varies greatly, consisting of mountains, deserts, plains, plateaus, glaciers, and other <a href="/wiki/Landform" title="Landform">landforms</a>. In physical geology, the land is divided into two major categories: <a href="/wiki/Mountain_range" title="Mountain range">Mountain ranges</a> and relatively flat interiors called <a href="/wiki/Craton" title="Craton">cratons</a>. Both form over millions of years through <a href="/wiki/Plate_tectonics" title="Plate tectonics">plate tectonics</a>. <a href="/wiki/Stream" title="Stream">Streams</a> – a major part of Earth's water cycle – shape the <a href="/wiki/Landscape" title="Landscape">landscape</a>, carve rocks, transport sediments, and replenish groundwater. At high elevations or <a href="/wiki/Latitude" title="Latitude">latitudes</a>, <a href="/wiki/Snow" title="Snow">snow</a> is compacted and recrystallized over hundreds or thousands of years to form glaciers, which can be so heavy that they warp the Earth's crust. About 30 percent of land has a dry climate, due to losing more water through evaporation than it gains from <a href="/wiki/Precipitation" title="Precipitation">precipitation</a>. Since warm air rises, this generates winds, though <a href="/wiki/Earth%27s_rotation" title="Earth's rotation">Earth's rotation</a> and uneven sun distribution also play a part. </p><p>Land is commonly defined as the solid, dry surface of Earth. It can also refer to the collective <a href="/wiki/Natural_resources" class="mw-redirect" title="Natural resources">natural resources</a> that the land holds, including <a href="/wiki/Rivers" class="mw-redirect" title="Rivers">rivers</a>, <a href="/wiki/Lakes" class="mw-redirect" title="Lakes">lakes</a>, and the <a href="/wiki/Biosphere" title="Biosphere">biosphere</a>. Human manipulation of the land, including <a href="/wiki/Agriculture" title="Agriculture">agriculture</a> and <a href="/wiki/Architecture" title="Architecture">architecture</a>, can also be considered part of land. Land is formed from the <a href="/wiki/Continental_crust" title="Continental crust">continental crust</a>, the layer of rock on which <a href="/wiki/Soil" title="Soil">soil</a>. <a href="/wiki/Groundwater" title="Groundwater">groundwater</a>, and human and animal activity sits. </p><p>Though modern terrestrial <a href="/wiki/Terrestrial_plant" title="Terrestrial plant">plants</a> and <a href="/wiki/Terrestrial_animal" title="Terrestrial animal">animals</a> evolved from aquatic creatures, Earth's <a href="/wiki/Earliest_known_life_forms" title="Earliest known life forms">first cellular life</a> likely originated on land. Survival on land relies on <a href="/wiki/Fresh_water" title="Fresh water">fresh water</a> from rivers, streams, lakes, and glaciers, which constitute only three percent of the water on Earth. The vast majority of human activity throughout history has occurred in <a href="/wiki/Habitable" class="mw-redirect" title="Habitable">habitable</a> land areas supporting agriculture and various <a href="/wiki/Natural_resource" title="Natural resource">natural resources</a>.
