How long does it take for the Sun's electromagnetic radiation to reach Earth?

• 5 minutes

• 8 minutes

• 10 minutes

You are less likely to see a total solar eclipse than a total lunar eclipse because

• the moon’s shadow covers all of Earth during a solar eclipse.

• new moon phases occur less often than full moon phases.

• only people on the daytime side of Earth can see a solar eclipse.

• the moon’s umbra only covers a small area on Earth’s surface.

Tides are caused mainly by

• Earth’s rotation on its axis, which causes water to move.

• differences in how much the sun pulls on different parts of Earth.

• strong winds blowing water onto coasts.

• differences in how much the moon and the sun pull on different parts of Earth.
