Which of the following is a characteristic of arid climates? A. temperatures that get colder as elevations rise higher B. short, cool summers and long, cold winters C. hot summers and cool winters D. hot summers and very cold winters

I would say the main charactersitic of arid climates like deserts from the selection is hot summers and cool winters because they usually are in a rain shadow so the skies are usually clear so clouds can't shield the ground from solar radiation and also at night and in the winter there is no cloud cover to insulate the environment so it gets cooler.
