Question
1. Currently what fraction of the Sun’s radiation energy that strikes the top of Earth’s atmosphere is absorbed by the Earth and what fraction is reflected away? Where does most of the absorption of radiation energy from the sun take place on Earth?Currently what fraction of the Sun’s radiation energy that strikes the top of Earth’s atmosphere is absorbed by the Earth and what fraction is reflected away? Where does most of the absorption of radiation energy from the sun take place on Earth?
2. Explain how the temperature at the Earth’s surface can be greater than the radiative equilibrium temperature of the planet. (Hint: where does much of the warming due to absorption of visible solar radiation happen?)
Explanation / Answer
1. 35% of the solar radiation are reflected back to the space
17% of the radiation is absorbed at different levels of the atmosphere.
Absorption is the process by which radiant energy is transfered to matter. The heat energy is entraped by the gas present in the atmosphere. The oxygen and ozone present in the earth atmosphere is transpfrmed by uv rays and also causes absorption of the radiation
