A desert is a landscape Landscape comprises the visible features of an area of land, including physical elements such as landforms, living elements of flora and fauna, abstract elements like lighting and weather conditions, and human elements like human activity and the built environment or region Region is most commonly a geographical term that is used in various ways among the different branches of geography. In general, a region is a medium-scale area of land or water, smaller than the whole areas of interest , and larger than a specific site. A region may be seen as a collection of smaller units (as in "the New England states") that receives almost no precipitation In meteorology, precipitation is any product of the condensation of atmospheric water vapor that is deposited on the Earth's surface. The main forms of precipitation include rain, snow, ice pellets, and graupel. It occurs when the atmosphere, a large gaseous solution, becomes saturated with water vapour and the water condenses, falling out of. Deserts are defined as areas with an average annual precipitation of less than 250 millimetres (10 in) per year,[1][2] or as areas where more water is lost by evapotranspiration Evapotranspiration is a term used to describe the sum of evaporation and plant transpiration from the Earth's land surface to atmosphere. Evaporation accounts for the movement of water to the air from sources such as the soil, canopy interception, and waterbodies. Transpiration accounts for the movement of water within a plant and the subsequent than falls as precipitation.[3] In the Köppen climate classification The Köppen climate classification is one of the most widely used climate classification systems. It was first published by the Russian climatologist Wladimir Köppen in 1884, with several later modifications by Köppen himself notably in 1918 and 1936. Later on, the German climatologist Rudolf Geiger collaborated with Köppen on changes to the system, deserts are classed as BWh (hot desert) or BWk (temperate desert). In the Thornthwaite climate classification system, deserts would be classified as arid megathermal Megathermal climates are sometimes split into two temperature-based subsets — equatorial and tropical — with "equatorial" denoting little or no variation in temperature throughout the year and "tropical" denoting significant seasonal variation, even though no month has an average temperature of below 18°C. In addition, climates.[4][5]
