3. 2 To spin on an axisrotate

4. 3 An imaginary line that passes through the center of the earth from the North Pole to the South Pole axis

5. 4 The layer of oxygen and other gasses that surround the earth atmosphere

6. 5 The specific path each planet follows orbit

7. 6 A year with 366 days instead of 365 ¼, happens every four years leap year

8. 7 one complete path around the sun revolution

9. 8 The day with the most hours of daylight Summer solstice

19. 18 Elevation affects climate because the ________ you go the colder it gets higher

20. 19 Which side of a mountain is the wet side? windward

21. 20 Areas near an ocean have ______ climates than areas inland milder

22. Be able to answer the following questions Where do you think an earthquake is more likely to occur – along North America’s Pacific coast or along North America’s Atlantic coast? Why? How do the shapes of South America and Africa support the theory of plate tectonics?

23. Explain how latitude affects climate. Be able to identify the lines of latitude shown in the diagram.
