How does Earth's position relative to the Sun cause the four seasons?. Single choice. (1 Point)

A. Earth orbits the Sun once a year and is in different positions with respect to the Sun every three months, resulting in the four seasons.

B. The tilt of Earth's axis with respect to its orbit changes back and forth approximately 46 degrees every six months.

C. Earth's axis is tilted with respect to its orbit, so, as it revolves around the Sun its tilt with respect to the Sun changes, resulting in the four seasons.

D. Earth rotates on its axis every 24 hours, and since the axis is tilted with respect to the Sun, different parts of the Earth experience different day-lengths, resulting in the four seasons.
