Major Deserts of the World
A desert is a region that receives very little rainfall (usually less than 250 mm per year) and has sparse vegetation. Deserts may be hot or cold, and they cover about one-third of the Earth’s land surface. Many deserts experience extreme temperatures, strong winds, and limited water resources.
Deserts are important in geography because they influence climate, ecosystems, mineral resources, and human settlements. Questions about deserts are frequently asked in UPSC, SSC, RRB, JKSSB, and other competitive examinations.
