Relative speed of revolution is fastest when the sun is nearest to the Earth and is slowest when it is at the farthest end. Relative speed of rotation is utmost at the equator and slowest at the poles. Moon revolves around the Earth in the same amount of time, 27 days. Latin word revolver, meaning ‘to roll back’Įarth takes only 24 hours to rotate on its axis.Įarth takes 365 days to revolve around the sun. Latin word rotare, meaning ‘to cause, to spin, roll, move in a circle’ The Earth’s axis is tilted at an angle of 23.5 degrees. Revolve is when something, usually a planetary body, moves around something in a usually elliptical path. Earth is slightly tilted (slanted) on its axis as it rotates on its axis and orbits around the Sun. Rotate is when something spins on an axis. In simple terms, remember that the Earth rotates around its axis and revolves around the Sun. So every time the moon goes around Earth it turns around one time this is the reason it always looks the same. It takes 225 Earth days for Venus to go all the way around the Sun. The moon rotates once about every 27 days, and revolves once about every 27 days. Because its so close to the Sun, a year goes by fast. These are the Northern and Southern hemispheres and the Eastern and Western hemispheres. Geographers, or people who study Earth, have divided the planet into two sets of two hemispheres. People use the word to describe one half of Earth. In revolving, the moon is a little different. Introduction A hemisphere is half of a sphere, or ball. Revolve is when something, usually a planetary body, moves around something in a usually elliptical path. To proceed or occur in a round or cycle come around again in the process of time recur.To turn around or rotate, as on an axis: The wheel revolves slowly.To move in a circular or curving course or orbit: The earth revolves around the sun.north and south poles.Īccording to, ‘Revolve’ is: Earth rotates from west to east around an imaginary line, which passes through the poles, i.e. One rotation is completed when a planet turns on its axis once.
An object rotates around the fixed point of rotation.
Key Difference: Rotate and Revolve describe different processes altogether.
