Earth's Hot Deserts Are Characterized by Extremely Low Precipitation

Multiple Choice

Earth's hot deserts are characterized by extremely low precipitation.Their locations at latitudes approximately 30° north and 30° south of the equator result from

A) the tilt of Earth's axis and the direction of Earth's rotation.
B) sunlight striking Earth at the steepest angle at the 30°N and 30°S latitudes.
C) warm equatorial air losing moisture as it rises, then descending due to high pressure at these latitudes.
D) air at these latitudes retaining its moisture in the atmosphere rather than allowing it to fall to Earth as precipitation.
E) equatorial air continuing to warm as it reaches the stratosphere, then releasing its moisture into the stratosphere before descending.
