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 position of the moon between earth and the sun
d. the speed at which earth rotates

Explanation:

To determine the primary cause of seasonal change, we analyze each option:

• Option A: Earth's axis is tilted at about 23.5 degrees. As Earth orbits the Sun, different hemispheres receive varying amounts of sunlight throughout the year, leading to seasons. This is the correct cause.
• Option B: Earth's distance from the Sun (elliptical orbit) has a minor effect, but not the primary cause of seasons.
• Option C: The Moon's position causes eclipses or tides, not seasons.
• Option D: Earth's rotation speed affects day - night, not seasons.

Answer:

A. the tilt of Earth’s axis
