Greenhouse Gasses and Global Warming

what is global warming

• when the earth is completely normal and nothing happens

• when the earth gets very cold and freezes up the planet

• a gradual increase in the overall temperature of the earth's atmosphere

• when earth gets really really really hot

Why does too much carbon dioxide in the atmosphere cause climate change?

 Which of the following activities contributes the most to carbon emissions globally?

• Deforestation
• Agriculture
• Burning fossil fuels
• Respiration

Which process accurately describes the formation of the greenhouse effect?

• The Sun's rays are reflected from the land back into the atmosphere.
• Increased solar energy is entering through the hole in the ozone layer.
• Aerosol gases become trapped and build up in the atmosphere.
• Heat radiating from the land and oceans is trapped in the troposphere.
