The angle at which sunlight hits earth is one of the most important factors impacting the average temperatures in a region. higher angle (more direct) sunlight warms earth more effectively. earth's axis is tilted by ~23°. earth currently makes a full rotation every 24 hours (the basis for our day). the tilt of the axis is why latitudes greater than 66° n don't receive any sunlight in the winter, or have any darkness in the summer. it is also why equatorial regions are warmest―they receive the most direct sunlight year-round. read the sentences below, and indicate which accurately describe the effects of earth's rotation and the angle of the sun.
