Space Unit Review

Genesis is making a computer model comparing the rotation of Earth to the rotation of the Sun. What information should she included in the model?

• The Sun rotates much more rapidly than Earth does.

• The Sun does not rotate, but Earth rotates once every 24 hours.

• The Sun is not a solid and its equator rotates faster than the rest of it.

• The Sun and Earth both take about 24 hours to complete a full rotation.
