Which of the following statements regarding Earth’s annual energy balance are TRUE (choose all that apply):

a Each year, the earth and atmosphere combined receive the same amount of energy from the Sun that they lose to space.
b Earth’s overall average equilibrium temperature changes only slightly from one year to the next.
c Over half of the incoming solar energy received at the top of the atmosphere is absorbed at the surface
d Winds and ocean currents play a vital role in transferring excess energy from equatorial regions to polar regions

Answer 1

Answer:

A. The total amount of energy received by the earth is sent back as ame amount by losing it to space.

Explanation:

Earth only receives a fraction of sunlight in the form of electromagnetic radiation. As 100 % energy comes from sun of which 50 % is absorbed by the earth features, land sea, and oceans.  20% is absorbed by the clouds and the atmosphere, and 30% is reflected by clouds making earth albedo of 35 %. This occurs 24 hr a day and is carried out in long wave terrestrial radiation. As compared to short term solar radiation.
