Answer 4

"Most of these are located at the latitudes of 30° North or South latitude; this is where air that was warmed at the equator falls back to the ground as cool, dry air (having lost its water as it rose wet and steamy over the equator).  These dry winds dry the land except for areas which are wetted by onshore breezes from warm offshore waters, such as the Gulf coast of the United States or the eastern coast of Indochina. Temperate deserts occupy the drier parts of the shaded areas in the map to the right.  In some of these areas it is difficult to distinguish "grassland" from "desert". Many of these are inland areas separated from oceanic moisture by mountain ranges; examples would be the Gobi Desert of Mongolia (the Himalayas) and the Great Basin of the southwestern US (The Sierra Nevada). ..."

"Many deserts are found in bands along 30 degrees latitude north and 30 degrees latitude south (between the red lines on the map).

Some deserts located by mountains and are caused by the "rainshadow" effect. As air moves up over a mountain range, it gets cold and loses the ability to hold moisture -- so it rains or snows. When the air moves down the other side of the mountain, it gets warmer. Warm air can hold lots of moisture, so it doesn't rain as much, and a desert is formed. ..."
