Explanation: 

Detailed explanation-1: -The motion around the sun along its orbit is called a revolution. The amount of time it takes for a single trip around the sun is called a period of revolution. The period for the Earth to revolve around the sun is 365.24 days or one year.

Detailed explanation-2: -Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time.

Detailed explanation-3: -So the Earth rotates around its axis as it revolves around the sun. It takes the Earth 365 days, or one year, to complete a revolution. Leftover momentum from when planets were forming makes the Earth, and all planets in the solar system, rotate and revolve.

Detailed explanation-4: -Earth makes one complete rotation on its axis every 23 hours and 56 minutes, which is rounded up to 24 hours.
