Jon Ahlquist 9/15/2006 MET1010 Intro to the Atmosphere 1 Chapter 3 Review Seasonal and Daily Temperatures The Earth and the Sun ± Looking down on the North Pole, in what direction does the Earth rotate? In what direction does the Earth go around the Sun? ± Near what compass point does the sun rise? ± Near what compass point does the sun set? ± How much does the Earth’s distance from the Sun vary during the course of a year? (Not much. The orbit is nearly circular. Farthest and closest distances are within 2% of average of 93 million miles.) The Earth and the Sun ± Why does the Earth have seasons? ± The Tropics of Cancer (Northern Hemisphere) and Capricorn (Southern Hemisphere) are at 23.5 degrees latitude. What is special about those latitudes? (The following Web site for Mazatlan, Mexico has a good discussion of the Tropic of Cancer, which is close to Mazatlan: http://www.maztravel.com/maz/explain/cancer.html) ± The Arctic and Antarctic Circles are at 90 – 23.5 = 66.5 deg latitude.
