Question

select the correct answer. what is the primary cause for the change in seasons?
a. the tilt of earth’s axis
b. the distance of earth from the sun
c. the positions of the moon between earth and the sun
d. the speed at which earth rotates

Explanation:

Seasons change primarily due to the tilt of Earth's axis (around 23.5 degrees). As Earth orbits the Sun, different hemispheres receive varying amounts of solar energy because of this tilt. Option A (the tilt of Earth’s axis) is correct. Option B: Distance from Earth to Sun (perihelion/aphelion) has minor effect, not primary. Option C: Moon’s position relates to tides, not seasons. Option D: Earth’s rotation speed affects day length, not seasons.

Answer:

A. The tilt of Earth’s axis
