2. This summer you are telling a friend about what you learned in ASTR 100, and he doesn't believe you when you say that the distance the Earth is from the Sun does NOT cause the seasons. Describe ONE observation that you could make about the Sun, the Earth, and/or the seasons that would provide evidence to back you up. Be sure to explain in each case how the observation is evidence supporting your position.
Answer: This is an excellent answer by a student: “I would fly him from Maryland to South America to see it is winter. I would point out the fact that the North and South hemispheres have opposing seasons. If proximity to the Sun caused the seasons would the northern and southern hemispheres not have the same seasons[?] Instead it is caused by the tilt of the Earth and how much [sunlight] is exposed to each hemisphere.” (continued)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
