Which statement best describes the orbit of Earth?
ruslelena [56]

Answer:

B. Earth rotates on its own axis and revolves around the Sun.

Explanation:

The earth moves not only in one way but in two ways. It revolves around its axis and revolves around the Sun.

We do not notice it because we are on Earth and we turn together with it.

When the Earth revolves around its (imagined) axis, we call such a movement a rotation, and when it revolves around the Sun - a revolution.
