The Earth takes about ________ to complete one rotation around its axis.
(A) 48 hours
(B) 30 days
(C) 24 hours
(D) 365 days
The Earth takes a complete turn on its axis every 24 hours. This is what we call a solar day—the time it takes for the Sun to return to the same position in the sky. If you were to measure a complete 360-degree turn (sidereal day), it would be a little shorter: 23 hours, 56 minutes, and 4 seconds. But for practical purposes, we just say a day is 24 hours.
