Earth is gradually rotating slower on its axis. This change in rotation rate will most likely cause the

• length of days on Earth to become longer

• phases of the moon to change more slowly

• changing of seasons on Earth to occur more quickly

• length of the orbit around the Sun to become shorter

How does the Sun's energy travel to Earth?

• by the magnetic fields between the Sun and Earth

• by the convection of heat through particles in space

• by the radiation of electromagnetic waves through space

• by the process of conduction of heat between the Sun and Earth

What has the greatest effect on the height of a tide?

• the revolution of Earth around the Sun

• the gravitational pull of the Moon

• the gravitational pull of the Sun

• the tilt of Earth on its axis
