Earth Space Science - Energy in the Atmosphere and Ocean

Hailey is creating a computer model to show what happens to energy from the sun when it reaches the Earth's surface.

Which of the following statements explains the energy budget on Earth?

• Most energy is made into food by plants.

• Earth's surface absorbs and re-emits equal amounts of energy.

• Earth's surface reflects more energy than the atmosphere.

• The atmosphere absorbs more energy than Earth's surface.

Hailey will need to include methods of heat transfer in her model. What type of heat transfer takes place from the sun to the Earth?

• Convection

• Conduction

• Expansion

• Radiation

The ozone layer absorbs energy and protects life on Earth. Some chemicals, called CFCs, have damaged the ozone layer. Which of these explains what happens when the ozone layer is damaged?

• Fewer UV rays reach the Earth's surface

• Fewer UV rays are absorbed by the atmosphere

• More UV rays are reflected back toward space

• Other parts of the atmosphere make up for the damaged ozone layer.

What form is the sun's energy that reaches us through space?

• electric

• magnetic

• magnetoelectric

• electromagnetic

The form of radiation that is similar to heat is

• infrared

• visible light

• ultraviolet

• radio waves
