A) Revolution refers to Earth's spinning on its axis, and rotation refers to Earth's changing seasons. B) Rotation refers to Earth's spinning on its axis, and revolution refers to Earth's spinning around the Sun. C) Rotation refers to Earth's spinning on its equator, and revolution refers to Earth's spinning around the solar system. D) Revolution refers to Earth's spinning on its axis, and rotation refers to Earth's spinning around the Sun. 10.
A) The change in distance is actually minimal. Earth's tilted axis is the real cause of seasons on Earth.
