Andrew Vile Hw Ch 4: 1,7,8,10,11 CT 2 Ch 5: 1,2,5,7,8,9,10 CT 1,2 October 24, 2007 Ch 4 1) Earths circulatory systems work to maintain the planet in a thermal and chemical balance (p 56) 7) Earth experiences different seasons throughout the year because of its changing distance from the sun and the earths tilt. The poles receive the most seasonal variability because depending on the earth’s time of year the earths tilt can either be facing the sun or facing away from the sun. The hemisphere that faces the sun receives much more solar energy and the one that faces away therefore determines the seasons. 8) An ocean surface rapidly transfers heat downward by turbulent mixing and into the atmosphere above by convection. Land surface rapidly looses heat to the atmosphere by convection but transfers heat downward slowly by conduction. The reason land and sea have different thermal responses is because they have different thermal properties. Water has a high thermal conductivity where as land dose not.

    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.
