Desert Climate and Geography: Formation processes, climatic features and geological structures of deserts.
Desert climate:
Desert climate is a type of climate characterized by low precipitation and high temperatures. Usually the annual rainfall is very low and thus deserts are known as arid regions.
Temperature differences are a prominent feature of the desert climate. During the day the temperature can be very high, but at night it drops quickly. This temperature change is called the day-night diurnal version.
Because the air humidity is low, deserts often have low humidity levels and high evaporation rates.
Desert climate occurs in regions far from the poles and equator, and various deserts are found in different continents of the world.
Formation Processes of Deserts:
Deserts are usually formed as a result of a combination of certain geological, topographical and climatic factors.
Generally, when the warm air mass rises and moves away from the region where it rises, precipitation occurs as this air mass cools and its moisture condenses. Therefore, deserts are usually located in low pressure regions.
In deserts, moist air masses are often blocked by mountains, preventing precipitation from reaching the deserts.
Winds can affect erosion processes in deserts and cause the deposition or transport of sand and soils.
Desert Geography:
Deserts can have a variety of geographic features. Deserts on Earth can include dunes, gravels, stony plains, salt flats and rocky terrains.
Sand dunes are formed as a result of the accumulation of sand, usually carried by the wind. Dunes are one of the most distinctive features of deserts.
Stony plains and pebbles are common surface types in regions with a desert climate. Generally, stones and gravel can accumulate in places with little rainfall.
Salt flats are large plains where salts accumulate in some deserts. As precipitation dissolves salts in these areas, these salts rise to the surface, and when the water evaporates, the salts crystallize.
This information has been prepared to provide basic understanding of desert climate and geography. Different regions of the world have different deserts and desert types, each with unique ecosystems and geographic features.
