Answer 1

The movement of the earth around the sun is called revolution

Explanation:

• The movement of  the earth around the sun in a fixed path or an orbit is  called Revolution.

• The earth takes $365$ $\frac{1}{4}$ days (one year) to complete one revolution.

• The axis of the earth is an imaginary line,  that makes an angle of $66\frac12^\circ$ with its orbital plane.

• The orbital plane is defined as the plane formed by the orbit.  

• Rotation of the earth is defined as the movement on its own axis.

• One full rotation of the earth takes around $23$ hours, $56$ minutes, and $4.09$ seconds.
