18 During which Moon phases do spring tides occur (new moon and full moon) (first quarter and third quarter) (crescent and gibbous)

6 During which phase is the Moon between Earth and the Sun (full moon) (new moon) (third quarter)

7 During which phase is the entire sunlit side of the Moon visible from Earth (new moon) (first quarter) (full moon)

5 Why does the same side of the Moon always face Earth (the Moon does not rotate) (the Moon rotates once in the same time it orbits Earth) (Earth blocks the other side)

13 What is the lighter part of a shadow where sunlight is partially blocked called (umbra) (penumbra) (maria)

12 Where can a total solar eclipse be seen (only inside the umbra) (everywhere on Earth) (only inside the penumbra)

17 What mainly causes tides on Earth (gravity from the Moon and Sun) (Earth’s rotation only) (clouds and rain)

8 Which Moon phase appears half lit after about one week (new moon) (first quarter) (full moon)

9 How long does one complete Moon phase cycle take (7 days) (29.5 days) (365 days)

14 What type of eclipse do people in the penumbra see (total eclipse) (partial eclipse) (no eclipse)

4 What is the side of the Moon that always faces Earth called (far side) (dark side) (near side)
