The cold and dry air continues to travel up the western side of the mountains ranges to the Death Valley and sinks to the surface, making it experience adiabatic heating, making the Western side of the mountain, which includes Death Valley, have a warm and dry climate ideal for desert conditions.

d) As southeast prevailing winds from the Atlantic are forced to climb up the Andes, and as the winds rise up the side of the Andes that doesn’t contain the Atacama Desert, it is cooled and the moisture in the air turns to rain. This means that there is a lot of rain on the side of the Andes that doesn’t contain the Atacama Desert. However, on the side that does contain the Atacama Desert, the cool air continues to travel up and sinks to the surface, making it experience adiabatic heating, which leads to the Atacama Desert having an arid climate, making it a desert. In addition to that, the reason this desert is a desert is b/c air generally rises at the equator because this is where maximum heating of the earth's surface occurs. Once it rises into the upper atmosphere, high level winds carry this air towards the poles. The air gradually cools and eventually falls back to earth between 20 and 25 degrees south, exactly where the Atacama is, creating high pressure. Descending air warms up and any moisture in it evaporates into water vapour which is a gas and so doesn't bring rain. In the Monte Desert, the prevailing winds climb up the side of one of the Andes mountains where the desert isn’t, and as the air moves up the side of that mountain, it cools and the moisture in that air turns into rain, meaning the side without the Monte Desert receives a lot of precipitation; however, on the side with the Monte Desert, the cool air continues to travel up and sinks to the surface, making it experience adiabatic heating, which leads to the Monte Desert having an arid climate, making it a desert.
