Earth's Energy Budget

Front

What is Earth's energy budget?

Back

Earth's energy budget is the balance between the energy Earth receives from the sun and the energy it radiates back into space. It can be summarized by the equation: energy in = energy out.

What type of light is primarily responsible for the warmth we feel from the sun?

Back

Infrared light is where most of the warmth that you feel from the sun comes from.

What can happen when solar energy hits clouds in Earth's atmosphere?

Back

When solar energy hits clouds, it can be reflected or absorbed.

Front

What is the main source of energy for Earth's climate system?

Back

The main source of energy for Earth's climate system is the sun.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm.

Front

What are the three main ways solar energy interacts with the Earth's surface?

Back

Solar energy can be absorbed, reflected, or transmitted by the Earth's surface.

Front

What is the role of clouds in Earth's energy budget?

Back

Clouds can reflect sunlight back into space and also absorb heat, affecting the energy budget.

Front

What is the difference between infrared radiation and ultraviolet radiation?

Back

Infrared radiation is associated with heat, while ultraviolet radiation has higher energy and can harm living organisms.
