Why is it colder at Earth’s north and south poles and hotter at the equator?
1. The sun hits straight at the equator, so a lot of solar energy is absorbed. The sun hits the poles at an angle that lets a lot of the energy pass by.
2. The sun hits the equator at an angle, so a lot of solar energy is reflected back.
3. Snow and ice at the poles absorbs solar energy and makes it warmer.
What is revolution?
1. A planet spinning around its axis.
2. A planet moving in a circle around the sun, or a moon circling around a planet.

Why does the Moon shine?
1. Because the Moon is a star.
2. Because the Moon gives off light.
3. Because the Sun's light is reflecting off of the Moon.
