Page 2: Astronomy 2 Review. 1. Compare the length of time it takes the Moon to rotate with the amount of time it takes the Moon to revolve once around the Earth

1. Compare the length of time it takes the Moon to rotate with the amount of time it takes the Moon to revolve once around the Earth.•Rotation = 27.3 days, Revolution = 27.3 days •They are the SAME!2. Why would you weigh less on the moon?•There is less gravity on the Moon.3. Identify when the Moon is closest to the Earth.•During Perigee

4. If the Moon does not produce it’s own light, then why does it light up the night sky?•It reflects light from the Sun.5. Compare and contrast craters with the maria found on the Moon.•Craters are created by meteorites and are empty. Maria were also created by meteorites but the space filled up with lava and cooled, creating the dark color of the maria.

31. Explain what causes the Earth to experience the different seasons?•Earth’s tilt•Earth’s revolution around the Sun32. Why does Earth experience Winter?•The Earth’s pole tilts away from the sun, and part of it receives indirect light (colder) and less daylight hours.33. Why does Earth experience summer?•The Earth’s pole tilts toward the sun, and part of it receives direct light (warmer) and more daylight hours.
