  3. What day will the shadows at local noon be the shortest here in Ann Arbor? Explain





  4. Why are the seasons reversed in the southern hemisphere?



  5. The Earth is at the farthest distance from the Sun (aphelion) around July 4, and closest to the Sun (perihelion) around January 4.  Does our closest approach to the Sun occur at the same time as the warmest weather in the northern hemisphere? In the southern hemisphere?  Explain.
