Which of the following distinguishes rotation from revolution?
Answer Details
The statement that distinguishes rotation from revolution is that "The earth rotates on its axis while it revolves around the sun in an elliptical orbit."
Rotation refers to the spinning of an object around its own axis. In the case of the Earth, it rotates on an imaginary line called its axis. This rotation is responsible for various phenomena like the change between day and night. As the Earth rotates, different parts of it are exposed to the Sun's light, creating the cycle of day and night.
Revolution, on the other hand, refers to the movement of an object around another object in space. In the case of the Earth, it revolves around the Sun in an elliptical orbit. This revolution takes approximately 365.25 days to complete, which gives us a year.
So, to summarize, rotation refers to the spinning of an object on its axis, causing phenomena like day and night. Revolution refers to the movement of an object around another object in space, giving us the concept of a year.
