What on Earth’s surface is highly reflective?

• Ice and Snow

• Ocean

• Ground

• Trees

What two things absorb the heat emitted from Earth’s surface?

• Clouds and Greenhouse Gasses (CO2)

• None of the above

What is the greenhouse effect?

• the ability of a surface to reflect away solar radiation

• to bend or throw back light or heat; to fold or turn back

• The warming of the Earth when water vapor, carbon dioxide, and gases absorb and radiate thermal energy.

• The change of a substance from a liquid to a gas

What is evaporation?

• the ability of a surface to reflect away solar radiation

• to bend or throw back light or heat; to fold or turn back

• The warming of the Earth when water vapor, carbon dioxide, and gases absorb and radiate thermal energy.

• The change of a substance from a liquid to a gas

What percentage of energy is absorbed every year by the Earth?
