greenhouse gas impacts

The amount of nitrogen in the atmosphere is...

• 21%

• 1%

• 80%

• 78%

• none

Carbon dioxide, water vapor and methane are gases that help...

• keep the atmosphere clean of toxic gases.

• keep the atmosphere warm enough for water to be liquid.

• keep the atmosphere from becoming too warm.

• keep UV light from getting to Earth's surface

The greenhouse effect refers to …

• the heating of ocean currents.

• the heating of the atmosphere due to glass windows.

• the trapping of heat from Earth created by sunlight.

• an increase in extreme weather events.

Which of the following is NOT a greenhouse gas?

• methane

• water vapour

• carbon dioxide

• nitrogen

Greenhouse gases (GHG) differ from nitrogen and oxygen in this way...

• GHG are heated only by conduction.

• GHG are red, so we can see them in the air.

• GHG absorb infrared energy.

• GHG are invisible to infrared energy.

The main idea of the story of the greenhouse effect (GHE) is...

• Earth's average temperature is cooler because of the GHE.

• Earth's poles are frozen because of the GHE.

• The GHE allows for water to be recycled.

• The GHE keeps Earth's temperatures relatively stable.

How is climate change altering precipitation in Canada.?

• Increasing extreme precipitation everywhere

• Increasing length of droughts everywhere

• Increase in both wet and dry extremes

• true

• false

In which ways do greenhouse gases affect the Earth?

• They cause some animal species to disappear.

• They impact the time in North America

• They increase food into farmers.

• They increase extreme weather conditions.

When we discuss greenhouse gases what is the main one we discuss?
