What term describes Earth's orbit around the Sun?

• A. Tilt
• B. Revolution
• C. Rotation
• D. Orbit

Answer: (B)

The main idea here is distinguishing motion around a central body from spin or the path itself. When Earth goes around the Sun, the term used for that moving-around is revolution. It describes the orbital motion—making a complete cycle about the Sun in one year. The path Earth follows is called its orbit, but revolution emphasizes the act of going around. So, for describing the Earth's movement around the Sun, revolution is the best fit. Tilt is about the tilt of Earth's axis, rotation is its daily spin on that axis, and orbit refers to the curved path itself.
