Question

Quizplus · Accepted Answer

The sidereal day only includes the Earth's rotation on its axis, while the solar day includes both the Earth's rotation and revolution around the Sun. All the other statements are true. The sidereal day is the amount of time it takes for the Earth to rotate once on its axis relative to the fixed stars, not accounting for its orbit around the Sun. Therefore, it does not include the Earth's revolution around the Sun, making statement E false.
