This document provides an overview of the module "Extreme Environments" which will study deserts (both hot and cold), mountainous climates, and tundra. It notes that hot deserts are found between 30 degrees north and south of the equator on the west or center of continents, listing several examples. The document explains that these hot deserts experience high temperatures because of the angle at which the sun's rays hit the Earth in those regions.
