Which factor causes earth’s seasons?
a. earth’s distance from the sun during its orbitb. the equator’s division of earth into northern and southern hemispheresc. the tilt of earth’s axis as it orbits around the sund. earth’s completion of its orbit around the sun every 365.25 days

C. the tilt of Earth’s axis as it orbits around the Sun

Explanation:

The hemisphere which is pointed towards the Sun, it is summer in that hemisphere.

The hemisphere which is pointed away from the Sun, it is winter in that hemisphere.

The tilt of the Earth at 23.4° is responsible for the length of a day in the hemisphere.

In the corresponding hemisphere the day is longer in the summer season and the day is longer in the winter season.

Hence, the seasons are caused due to the fact that tilt of Earth’s axis as it orbits around the Sun.
