They are mostly found mainly in rain shadow areas which are leeward of a mountain range with respect to the wind direction. In deserts, the atmospheric air is very dry, and the daytime temperature is high."

Formed:
* Replacement of the Tethys Sea with the Arabian Peninsula around 7 to 11 million years ago. Replacing water with land, which reflects less sunlight, altered the region's precipitation patterns which caused the area to dry out over time.

Reason: I have lived in Texas my whole life so I am used to the hot and dry weather. I have always been intrigued by polar deserts since I live in the opposite environment.
