In geography, a plain, commonly known as flatland, is a flat expanse of land that generally does not change much in elevation, and is primarily treeless.
Plains are one of the major landforms on earth, being present on all continents and covering more than one-third of the world's land area.
[1] Plains are one of the major landforms on earth, where they are present on all continents, and cover more than one-third of the world's land area.
Biomes on plains include grassland (temperate or subtropical), steppe (semi-arid), savannah (tropical) or tundra (polar).
[4] Plains in many areas are important for agriculture because where the soils were deposited as sediments they may be deep and fertile, and the flatness facilitates mechanization of crop production; or because they support grasslands which provide good grazing for livestock.
