Daniel Carter, ATOC 1060, Homework #1 11. Venus’ effective radiative temperature is 219.730 K while Earth’s is 255.020. It is surprising that Venus’ albedo is .80 and earth’s is .30. Venus is closer to the sun, yet absorbs less energy. 12. Venus’ distance from the sun is .72 AU while Earth’s is 1 AU. Venus is therefore closer to the sun and receives more energy. Also Venus’ greenhouse radiation (510.270) is significantly higher than Earth’s (32.98) which makes the planet hotter. 13. Mars is further from the sun than Earth is. Mars is 1.52 AU from the sun, while Earth is 1 AU. The solar flux of Mars is much lower than Earth’s as well. Earth’s solar flux is 1370 Watts/m^2 while Mars’ solar flux is at 592.970. Mars receives less sunlight than Earth; this is the most important factor when considering the planet’s temperature. 14. The Moon is colder than the Earth because the moon has almost no greenhouse radiation at .042 K. Earth’s greenhouse radiation is 32.98 K. Almost no energy the moon receives is absorbed, so most becomes infared light.

    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.
