How long does it take the Earth to rotate once on its axis?
 A 24 hours B 28 days C 365 ¼ days D 26, 000 years
Explanation:

Detailed explanation-1: -The time it takes Earth to rotate so the sun appears in the same position in the sky, known as a solar day, is 24 hours. However, the time it takes Earth to complete one full rotation on its axis with respect to distant stars is actually 23 hours 56 minutes 4.091 seconds, known as a sidereal … day.

Detailed explanation-2: -The Earth rotates on its axis relative to the sun every 24.0 hours mean solar time, with an inclination of 23.45 degrees from the plane of its orbit around the sun.

Detailed explanation-3: -How much time does it take to complete one rotation? Q. The earth takes 24 hours to rotate about its own axis.

Detailed explanation-4: -Every 24 hours (or rather 23 hours, 56 minutes and 4, 1 seconds) the Earth completes a rotation cycle, spinning around itself at nearly 1, 7 kilometers per hour.

Detailed explanation-5: -The sidereal day happens each time Earth completes a 360-degree rotation. That takes 23 hours and 56 minutes. The solar day-the one humans count in the calendar-happens when Earth spins just a little further, and the sun is at the same point in the sky as it was 24 hours ago.
