What causes the solar heating of Earth to have seasonal variations?

a. The length of the Earth's rotation
b. The tilt of the Earth's axis from the sun
c. The Coriolis Effect
d. The shape of the Earth’s rotation around the sun


ANS: B
The Earth has a 23 ? tilt. Due to this rotational axis, there is a change in the proximity to the sun as
the Earth moves away and towards the sun. This causes seasonal variations, especially in the midlatitudes.
Information can be found in the section The Atmosphere Moves in Response to Uneven Solar
Heating and Earth's Rotation.
