Which term refers to the movement of Earth in its orbit around the sun?

The term that refers to the movement of Earth in its orbit around the sun is "revolution." This term specifically describes the path Earth takes as it travels around the sun in a nearly circular orbit, which takes approximately one year to complete. During this time, the Earth's position relative to the sun changes, leading to the variations we observe in seasons.

The concept of revolution is distinct from rotation, which refers to the spinning of Earth on its axis. This rotation accounts for the day-night cycle. While circulation generally relates to the movement of fluids, such as air and water, translation sometimes describes a change in position but isn't typically used to refer to celestial movement in this context. Thus, revolution is the precise term that describes Earth's orbit around the sun.
