1 Greenhouse Gases

What role do greenhouse gases play in our atmosphere?

• They cool the planet by reflecting sunlight.

• They trap the Sun’s energy, making the planet warm.

• They absorb harmful UV rays from the Sun.

• They increase the planet's oxygen levels.

What is the primary role of CO2 and other gases in the atmosphere according to the greenhouse effect?

• They reflect sunlight back into space.

• They trap heat, keeping the Earth warm.

• They cool the Earth's surface.

• They absorb all sunlight.

What happens to some of the sunlight that hits the Earth?

• It is completely absorbed by the oceans.

• It is reflected back into space.

• It turns into wind energy.

• It disappears into the atmosphere.

What is albedo?

• The percentage of incoming sunlight that is absorbed by a surface.

• The percentage of incoming sunlight that is reflected from a surface.

• The percentage of incoming sunlight that is transmitted through a surface.

• The percentage of incoming sunlight that is refracted by a surface.

Which of the following surfaces has a high albedo?

• Asphalt

• Ocean

• Fresh snow

• Forest

Which surface is likely to have the lowest albedo?

• Ice & Snow

• Clouds

• Asphalt

• Sea ice

What happens to some of the incoming solar radiation after it reaches the Earth's surface?

• It is completely absorbed by the atmosphere

• It is reflected back into space

• It is converted into sound energy

• It is transformed into chemical energy

What is the role of greenhouse gases in the atmosphere according to the diagram?

• They absorb UV radiation and emit visible light

• They absorb infrared radiation and emit it back into the lower atmosphere

• They reflect all solar radiation back into space

• They convert infrared radiation into chemical energy

What is the effect of infrared radiation being absorbed and re-emitted by greenhouse gases?

• It cools the Earth's surface.

• It causes the Earth to spin faster.

• It warms the Earth's surface and the lower atmosphere.

• It creates more clouds.
