Question details

Balances (show your work for each part on a separate page) 1. Planetary Energy What would the Earths average radiating temperature be if the planetary albedo were 10% instead of 30%? (with 30% albedo, the average radiating temperature is 255 K) 15 points a) what would the Earths average radiating temperature be if the albedo were 70%? 15 points b) What would the Earths average radiating temperature be if the solar constant were 1030 w/m2 (ie.-75% of modern luminosity)? 15 points! c) Venus and Mars orbit the Sun at average distances of 0.71 astronomical units (AU) and 153 AU, respectively. What is the solar flux at each planet? [10 points] Hint: Earths orbit is 1 AU and its solar flux (S) 1370 W/m2 | d) Venus has a planetary albedo of 0.77 and Mars has an albedo of 0.25. Given this, and the answer to part (b), what are the effective radiating temperatures of eaclh planet? 110 points e) ) The mean surface temperatures of Venus and Mars are 730 K and 218 K. What is the magnitude of the greenhouse effect on each planet (in degrees Kelvin)? 15 points
