Earth Science Climate #3 Name:Latitude continued page 519 and 520Solar Energy and Latitude1. What is solar energy?2. What does it do to the Earth?3. What determines the amount of direct solar energy a particular region of the planet receives?4. What does Figure 3 show?5. At what degree angel does the sun hit the equator?6. True or False: When the sun hits the equator at a 90 degree angel, a small area of the Earth’s surface receives more direct solar energy than at a lesser angel.7. What is the result of a small area of the surface of the Earth getting more direct solar energy?8. What is the difference between how the sun hits the equator and how the sun hits the poles?9. What is the result of the answer to #8?10. Watch this little animation: HYPERLINK " that the intensity of light that shines on a surface depends on the angle at which the beam strikes the surface. The shallower the angle, the more the light spreads out, resulting in a lower intensity. Observe how the angle affects light intensity as you change the angle.What did you observe?11. Explain why there is a difference in climate between areas at 0 degrees latitude and areas at 45 degrees latitude:12. Find a city located on or close to 0 degrees latitude and another one at 45 degrees latitude. State the name of the cities and the latitudes:A.B. 13. Look up the current weather for each of your cities and record below. Be sure to include the date and time of your data collection as well as the current temperature, maybe humidity, wind speed, time of sun rise, time of sunset, etc.:A.B. 14. Summarize your results for #12 and write a conclusion of your findings:Seasons and Latitudes (page 520)15. True or False: In most places in the United States, the year consists of four seasons.16. Do all places on the plant have seasonal changes?17. Explain your answer to #16:18. Why do seasons happen?19. What does the tilt of the Earth affect?20. What is Figure 4 illustrating? 21. Reading check: Why is there less seasonal change near the equator? 22. How would seasons be different of the Earth did not tilt on its axis?23. What hemisphere do we live in?24. Why do our winter months have shorter days and cooler temperatures?25. What is going on in the Southern Hemisphere during our winter? Explain why:26. During what months does Australia have winter? Explain why:27. Look up the weather in Sydney, Australia for today. Write down the weather conditions and write about how this data reinforces your answer to #25.
