Question

what is responsible for setting up the differences between the tropical, temperature, and polar zones?
a. earths revolution
b. precession
c. earths tilt
d. the polar jet stream

Explanation:

Earth's tilt causes different latitudes to receive different amounts of solar radiation. The tropical zone gets more direct sunlight, the polar zones get less, and the temperate zone is in - between. Earth's revolution (A) is about its orbit around the Sun and is related to seasons but not the fundamental difference in zones. Precession (B) is a slow change in the orientation of Earth's axis and has a long - term (thousands of years) effect on climate but not the basic zone differences. The polar jet stream (D) is a high - altitude wind and affects weather patterns within the zones but does not set up the zones themselves.

Answer:

C. Earth's tilt
