Most of the worlds deserts occur in what zone?

The majority of the world's deserts occur in the subtropical high-pressure zones or the horse latitudes, which are located between 23.5° and 30° latitude north and south of the equator. This zone is characterized by descending air, which compresses and heats as it sinks, leading to warm and dry conditions conducive to desert formation. The subtropical deserts include famous hot deserts like the Sahara Desert in Africa, the Arabian Desert in the Middle East, the Atacama Desert in South America, and the Australian Outback.
