In which region indicated in the image would a rain shadow desert most likely be formed?
C
Match the type of desert to process(es) that cause their formation.
Coastal desert: Cold upwelling waters cool the air and limit the amount of moisture it can hold. Subtropical deserts: Global atmospheric circulation patterns result in a zone of high pressure which brings in dry descending air. Rainshadow deserts: Mountains force air to rise and cool causing precipitation on the upwind side and air to descend, warm, and become less humid on the downwind side. Polar deserts: Cold dry air and often frozen water limit the amount of humidity in the air. Continental deserts: Dry air results when winds blow long distances without encountering sources of moisture.
