Test Review
Seasons,
Moon Phases,
and Tides

2. Rotation and Revolution

3. 1. What is Earth’s axis?
An imaginary line that runs from the north pole to the south pole
The earth rotates on its axis causing day and night

4. 2. What is the difference between Earth’s rotation and revolution?
Rotation: Earth rotates (spins) its axis causing day and night (24 hours)
Revolution: Earth revolves around the sun in 1 year
Night
Day

5. 3. What causes day and night?
Earth rotation around its axis
Night
Day

6. 4. What causes seasons
Seasons are caused by earths revolution and its tilted axis. As is revolves, part of the earth is either facing towards the sun or leaning away from the sun

7. 5. Label the diagram: Spring Fall Summer Winter Winter Summer Fall

8. 5. Label the diagram:
Earth revolution
Earth’s Rotation

9. Lunar Cycle

10. 1. What is the role of the Sun in the occurrence of the lunar cycle?
The sun illuminates the Moon’s surface in a predictable pattern creating moon phases

11. 2. How long is one lunar cycle/moon’s revolution around earth?
29.5 days – about a month

12. Waxing Crescent
Waning Crescent
3rd Quarter
First Quarter
Full Moon
Waning Gibbous
Waxing Gibbous

13. 4. What do the terms waxing and waning mean?
Waxing: Growing
Waning: Shrinking
The light on the right is getting bright
The Light on the Left is getting Less

14. 5. What do the terms gibbous and crescent mean?
Gibbous: More than half
Crescent: less than half

15. 6. What does the term quarter moon mean?
Quarter moons are when we can see half of the lighted part of the moon. To us it looks like half of the moon is lit.

16. 7. What is a meant by the terms a full moon and a new moon?
Full Moon: The entire lighted side of the moon can be seen
New Moon: Earth can only see the dark side of the moon

17. Tides

18. 1. What affect does the gravitational pull of the moon and the sun have on Earth?
Gravitational Pull: The pull on the earth due to the sun, moon, and earth rotation on its axis which causes tides

19. 2. What causes tides to occur on Earth?
The moon and the sun both have a gravitational pull on the earth, which pulls on the waters of the earth creating tides

20. 3. What is a high tide? Low tide?
High Tide: Where the water levels rises twice a day
Low Tide: Where the water level falls twice a day
Both are caused by the gravitational pull from the moon and earth’s rotation

21. 4. What is a neap tide? Spring tide?
Spring Tide: When the sun and the moon are both in line with the earth, they pull in the same direction, causing the greatest difference between high and low tides.
Neap Tide: When the moon and the sun are at a 90 degree angle, they pull in different directions, causing the least amount of difference in high and low tides

22. 5. What moon phases go with neap tide
5. What moon phases go with neap tide? What moon phases go with spring tide?
