Option D, Cool dry air descends at 30° latitude which reflect that most deserts occur at approximately 30° latitudes.
Near 30 degrees north latitude and 30 degrees south latitude, when the warm equatorial air starts to descend, are where the majority of the world's deserts are found. Large amounts of water from the surface of the land are vaporised by the dense, warming, descending air. The environment that results is quite dry. Circulation patterns and precipitation patterns are both influenced by the motion of the air currents. At roughly 30° north latitude, air builds up because of the earth's rotation. At this latitude, a belt of high pressure is created when some of the air sinks. As it reaches the surface, the sinking air moves north and south.
Due to the lack of water, the areas at 30 degrees north and south latitude are usually deserts with more drier air. The atmosphere's chilly, dry air will descend back to the earth's surface at this location.
