Deserts are commonly found between 10 and 30 degrees north and south of the equator due to factors that limit rainfall. There are four main reasons for this - trade winds, convectional rainfall patterns near the equator, high rates of evaporation, and intense solar radiation in these subtropical regions. The four types of deserts are trade wind deserts, rain-shadow deserts, coastal deserts, and monsoon deserts.

3. Where are deserts found and why? There are 4 main reasons that a region may be a desert but it is always to do with factors that limit the amount of rainfall to the area . A general pattern can be seen . Many deserts are found in the sub-tropics between 10 and 30° N and S of the equator. Why is this? Why are most deserts found between 10°and 40° N and S of the equator?
