It is a natural landscape shaped by extreme arid climate, characterized by scarce precipitation, high evaporation rate, sparse vegetation, and poor soil. Distributed worldwide, from tropical to temperate regions, including the Sahara Desert, Arabian Desert, Gobi Desert, and the Great Sandy Desert in Australia. The formation is usually related to geographical location, climatic conditions, and geological history. In tropical regions, deserts are often formed due to the influence of high-pressure zones, while in temperate regions, it may be due to terrain blocking the entry of moisture. The earth's surface is often composed of sand, gravel, or saline alkali land, forming different landforms such as sand dunes, gravel deserts, or salt deserts under the action of wind.
