Question

Which of the following best describes the solar radiation absorbed by and radiated from earth? a. Most incoming solar energy is absorbed by the atmosphere. b. Only a small fraction of energy radiating from Earth is from the atmosphere. c. The Earth’s surface is responsible for a small fraction of heat radiation to space. d. Earth’s surface absorbs little of the energy that strikes as solar radiation.

Answer 1

Which of the following best describes the solar radiation absorbed by and radiated from earth?
c. The Earth’s surface is responsible for a small fraction of heat radiation to space. i think

Answer 2

Option C, The Earth’s surface is responsible for a small fraction of heat radiation to space

Step-by-step explanation:

Earth’s surface absorbs large amount of solar radiation. In order to maintain the energy budget of earth, it radiates back energy from the atmosphere to the space.

As per the estimates, earth radiates nearly 59 % of the incoming solar radiations which includes the heat energy radiation from the following sources:

a) Direct absorption (23%)

b) Evaporation (25%)

c) Convection (5%)

d) Thermal infrared radiation (6 %)
