Question

14.seasonal changes on earth are primarily caused by the a. parallelism of the suns axis as the sun revolves around earth b. changes in distance between earth and the sun c. elliptical shape of earths orbit around the sun d. tilt of earths axis as earth revolves around sun base your answers to questions 15 and 16 on the diagram below, which represents the earth at a position in orbit around the sun, the suns rays at solar noon, and the direction to polaris. letters a through d represent positions on the earths surface.

Explanation:

The tilt of Earth's axis as it revolves around the sun causes different parts of the Earth to receive varying amounts of sunlight at different times of the year, leading to seasons. The other factors like the elliptical shape of Earth's orbit and changes in distance between Earth and the sun have a much smaller impact on seasons compared to the tilt. Parallelism of the sun's axis as the sun revolves around Earth is an incorrect concept as the sun does not revolve around Earth.

Answer:

d. Tilt of Earth's axis as Earth revolves around sun
