The Earth's surface temperature is about 15∘C, far above the average temperature of the atmosphere of −33∘C, mainly because:

a)The visible light from the Sun is almost completely absorbed by the atmosphere and radiated back to the Earth’s surface but in a form of infrared radiation.

b)The infrared radiation from the Sun is almost completely absorbed by the atmosphere and radiated to the Earth.

c)The infrared radiation from the Earth’s surface is almost completely absorbed by the atmosphere and a large fraction of it is radiated back to the Earth’s surface.

d)The ultraviolet light from the Sun is absorbed by the ozone in the atmosphere and radiated back to the earth.

e)The surface of the Earth absorbs the Sun’s radiation but the atmosphere doesn’t absorb any radiation.

In the stratospheric level of the atmosphere there is a high level of ozone, O3. This ozone absorbs much of the ultraviolet light from the sun and thus protects life in the surface of the Earth from harmful high level of ultraviolet radiation. Explain why one chlorofluorocarbon (CFC) molecule in the ozone layer is capable of breaking down hundreds and even thousands of ozone molecules?

Assuming the Sun radiates as a blackbody at a temperature of 5800 K, calculate the expected surface temperature of the Earth, assuming that the Earth also acts as a perfect blackbody. Assume the Earth absorbs an amount of energy proportional to its cross-sectional area, but radiates as a spherical blackbody. If the Earth is in thermal equilibrium with outer space, then the energy received (mostly at visible wavelengths) must equal the amount of energy re- radiated (mostly) in the infrared....

Part C: The Earth’s atmosphere can be considered to be a heat engine, in the Carrot (thermodynamic) sense. The temperature at top of the upper atmosphere is that necessary to radiate infrared energy back into space so to balance that gained from the sun. The surface is heated by the sun and insulated by the atmosphere (the greenhouse effect) so it’s warmer. 1) What is the efficiency of this heat engine if the air at Earth’s surface is 288 K...
