Question

What does the Earth's energy budget give us an idea about? Select all that apply. How much energy is reflected from Earth back into space How much energy is used by humans How much energy is used by animals and nature How much solar energy comes into Earth's atmosphere

Answer 1

The answers that apply are;

1. How much energy is reflected from Earth back into space
2. How much energy is used by animals and nature
3. How much solar energy comes into Earth's atmosphere

To find the earth’s energy budget, one has to derive the amount of energy received by the earth from the sun and how much is radiated back to space. The difference is that drive the earth heat engine. Different earth’s spheres (such as atmosphere, biosphere, and hydrosphere) have a significant role in determining the earth’energy budget.

Answer 2

The correct answer is option A , B, C and D, All the options are correct

Reason-

The earth’s energy budget basically involves two major components-

a) Incoming energy coming from the sun

b) Outgoing energy from the Earth and its atmosphere

Within these two major processes, the energy is absorbed, reflected and radiated by various components on earth such as it is utilized by plants to produce food and oxygen, utilized by humans to produce energy, some energy is reflected by clouds, some is radiated by the atmospheric particles etc. When the energy budget is balanced, the earth’s temperature is constant else the temperature either increases or decreases. The energy which is absorbed by the atmosphere or the earth’s surface move around through the processes of convection, evaporation, or in the form of latent heat
