Question

Quizplus · Accepted Answer

The Patagonian desert is caused by the rain shadow effect created by the Andes mountains and the onshore South Pacific westerlies. As moist air from the ocean rises over the mountains, it cools and loses its moisture, creating a dry area on the other side (the Patagonian desert). Additionally, the high elevation of the Andes contributes to the dryness of the region.
