G8 9.3

10 What is an eclipse (the Moon disappears) (a shadow caused when one object in space blocks another) (the Sun gets brighter)

20 During which Moon phases do neap tides occur (new moon and full moon) (first quarter and third quarter) (only during eclipses)

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

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

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

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

1 Why does the Moon appear to change shape during the month (Earth changes shape) (different parts of the lit Moon are visible from Earth) (the Moon produces different amounts of light)

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

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

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

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

16 What are tides (changes in wind direction) (the rise and fall of ocean water) (waves caused by boats)

2 What causes the Moon to shine in the night sky (it produces its own light) (it reflects sunlight) (it is made of fire)

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

15 Why are lunar eclipses visible to more people (the Moon is larger than Earth) (Earth’s shadow is much larger) (the Sun becomes brighter)

19 What causes spring tides (the Sun and Moon pull at right angles) (the Sun Moon and Earth line up) (Earth stops rotating)

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

11 What is the darkest part of a shadow called (penumbra) (umbra) (tide)

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)

3 What are the dark flat areas on the Moon called (craters) (maria) (penumbra)
