5. Question 4 O Draw a diagram that shows the position of Earth at four different times during the year (summer, spring, fall, and winter) and label each season. Be sure to include the tilt and the sun in your diagram.

6. Answer

7. Question 5 O What is happening in the Arctic Circle during the December Solstice? O People in that area are experiencing 24 hours of darkness

8. Question 6 O Kevin travels from the U.S. to Australia for the summer, but when he gets there it feels more like winter. Explain this!
