Greenhouse effect

The gas that is most abundant in the atmosphere is

• oxygen
• nitrogen
• carbon dioxide
• argon

What absorbs ultraviolet rays in the atmosphere?

• troposphere
• stratosphere
• ozone layer
• greenhouse gases

Which of these sets of three items produce CFCs

• cars, factories, and cardboard
• spray cans, cardboard, insulation
• spray cans, refrigerant, cardboard
• spray cans, refrigerant, insulation

The Earth acts like a greenhouse that catches and traps heat from the sun.

• true
• false

What does this diagram illustrate?

• Ozone Layer
• The Greenhouse Effect
• Ultraviolet Radiation
• Layers of the atmosphere

This traps heat and absorbs gases (carbon dioxide, methane..) and keeps the earth warm. Allowing heat to go back into space prevents Earth from becoming too warm

• Ozone Layer
• The Greenhouse Effect
• Greenhouse Gases
• Mesosphere

What do we call gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect?  

• Bad Gases
• Ozone Gases
• Greenhouse Gases
• Atmospheric Gases

This protects us from harmful UV rays from the sun

• Troposphere
• Stratosphere
• Greenhouse Effect
• Ozone Layer

The Montreal Protocol banned the use of CFCs. What so they hope this will do for the ozone layer?

• Deplete it completely
• Make the ozone hole smaller
• Make the ozone hole larger
• Thin the layer to allow more gas to escape

Which of these sets lists the major greenhouse gases?

• Nitrous Oxide, Carbon Dioxide, and Methane
• Nitrogen, Oxygen, Argon
• Nitrous Oxide, Oxygen, and Methane
• Nitrogen, Carbon Dioxide, and Methane
