Question

Why is the atmosphere heated chiefly by radiation from Earth's surface? Choose all that apply. Earth emits long-wave radiation, which is readily absorbed by the atmosphere. Even though the short wavelengths from the Sun indicate that it is hotter than Earth, which emits long wavelengths, Earth's wavelengths are opaque to its atmosphere; thus, heat that was reemitted by Earth is retained within the atmosphere. Earth emits short-wave radiation, which is readily absorbed by the atmosphere. Earth emits short-wave radiation, which easily passes through the atmosphere without absorption. Earth is a good emitter of radiation, even though it is a poor absorber of radiation.

Answer 1

Earth emits longwave radiation, which is readily absorbed by the atmosphere.

Step-by-step explanation:

• As earth emits longwave radiation and the sun emits short wave radiation the amount of energy that reaches the land is about 50% of what is emitted from the sun during the daytime.

• A smaller part of the energy is re-radiated back from the earth in the form of a black body towards the outer space and hence is in the form of longwave radiation. The longwave radiation is carried out at night time and is a gradual process.
