Back

The Sun appears to move across the sky due to the rotation of the Earth on its axis.

Front

What are the two main motions of the Earth?

Back

The two main motions of the Earth are rotation (spinning on its axis) and revolution (orbiting around the Sun).

Front

What would happen if Earth rotated more slowly?

Back

If Earth rotated more slowly, there would be longer days and nights.

Front

What is the relationship between the Earth and the Moon?

Back

The Moon orbits around the Earth, and its phases are caused by the relative positions of the Earth, Moon, and Sun.
