4. Row 1, Col 1 Earth ’ s rotation takes about how long? 24 hours

5. 1,2 What is an object ’ s weight? Force of gravity on object

6. 1,3 Why do we only ever see one side of the moon? It rotates on its axis as it revolves around Earth=same amount of time

7. 1,4 Why do temperatures vary so much on the moon? No (very little) atmosphere

8. 2,1 What causes day and night? Rotation of Earth on its axis

9. 2,2 What 2 factors act together to keep Earth in orbit around Sun? Inertia & Gravity

10. 2,3 What is the difference between spring and neap tides? How many spring tides do we have in a lunar month? Spring new/full and neap 1st and last/2 spring in a month

11. 2,4 Explain the collision theory? DD Theory on how the moon was formed

12. 3,1 What is a leap year? When and why does it occur? Adjustment of calendar every 4 years/Feb. 29

13. 3,2 What would happen to the force of gravity between Earth and the Moon if the distance between them decreased? How would that effect us here on earth? The force of gravity between them would increase

14. 3,3 What type of eclipse is this? During which phase does it occur? What are you seeing here?

15. 3,4 Which moon features are linked to ancient volcanic activity? Maria

16. 4,1 What are the two reasons the Earth has season? 1. Its axis is tilted while it moves around the Sun

17. 4,2 What is the difference between your mass and weight? Give an example

18. 4,3 What is the difference between a lunar and solar eclipse? Name 2 ways When they occur(night/day) and how(full/new)

19. 4,4 Where on the moon has evidence of water been found? In which state of matter would you likely find it? At the poles, solid

20. 5,1 Prominence What is this feature and why does it form?

21. 5,2 What 2 factors determine the strength of gravity between 2 objects? Masses of objects and distance between them

22. 5,3 Explain why most coastal regions have two high and two low tides a day? 25 hours/ 2 sides of earth have high two have low

23. 5,4 Name the 8 phases of the moon in order beginning w/ the new Moon DD
