2. Earth’s Rotation Cause
Earth spins on a tilted imaginary line called an axis.
Earth spinning on its axis is called rotation.

4. Earth’s Revolution Cause Earth orbits or revolves around the Sun.
Earth moves in a regular path around the Sun
The Sun’s gravity keeps all of the planets in orbit around it.

5. Effect One revolution = about 365 ¼ days
= one year
This produces winter, spring, summer, and fall as we go around the sun.
Summer occurs in the Northern Hemisphere when we are tilted towards the sun.
Winter occurs in the Northern Hemisphere when we are tilted away from the sun.
