Question

question 12 of 25
how long does one of earths rotations take?

a. 1 day

b. 1 month

c. 1 year

d. 1 minute

Explanation:

To determine the time for one Earth's rotation, we recall astronomical concepts: Earth's rotation on its axis (causing day - night cycle) takes about 24 hours, which is 1 day. A month is related to lunar cycles or Earth's orbit around the Sun (lunar month ~29.5 days, calendar month varies), a year is Earth's orbit around the Sun (~365 days), and 1 minute is too short. So the correct option is A.

Answer:

A. 1 day
