Click on the link for the animation above. Then click on "Set Earth's Inclination Angle to that of: Earth." Drag the globe around the orbit. Explain what happens to the path of the Sun in the sky when moved through Winter, Spring, Summer, and Autumn. *
Click on the link for the animation above. Then click on "Set Earth's Inclination Angle to that of: Earth." Move the globe around while watching the sunlight angle and average daily temperature at observation site graphic. What happens to the temperature at the observation site when the angle of the sun becomes more direct to the surface? *
What is different about solstices and equinoxes? Explain what each one is and why they are different. *
How does the fact that visible star constellations change throughout the year give evidence of the earth's revolution around the Sun? See page 669. *
