The earth completes one revolution in …………… (a) 366 days (b) 370 days (c) 365 1/4 days (d) 366 1/4
Correct option is C) 365 1/4 Earth's revolution around the Sun takes much longer than its rotation on its axis. One complete revolution takes 365 1/4days, or one year. The Earth revolves around the Sun because gravity keeps it in a roughly circular orbit around the Sun.
