The movement of earth around the Sun in a fixed path is called a revolution.
Earth has two types of motions; Rotation and Revolution. Rotation refers to the movement of earth on its own axis.
Revolution is the time taken by earth to complete one revolution around the Sun. Earth takes one year to complete a revolution and the speed is about 68,000 miles per hour.
The earth moves around the sun in an oval shape known as the ellipse. This path of movement is known as the Orbit.
The gravitational force of Earth causes the revolution.
The Revolution of earth results in seasons. Earth moves on a tilted axis, and thus different parts of the Earth receive different amounts of sunlight.
The earth’s axis makes an angle of 66 ½ degrees with the orbital plane.
