Global Warming Revision Quiz

Global warming can lead to

• deforestation

• climate change

• oil spills

• litter

The three (3) primary heat absorbing gases in the atmosphere are (CHOOSE THREE):

• Carbon dioxide

• Water vapor

• Nitrogen

• Hydrogen

• Methane

What do greenhouse gases do in our atmosphere?

• They absorb radiation given off by the Earth

• They keep all the air within the Earth

• They block harmful radiation from reaching the Earth

• They make the Earth cooler

Which of the following would occur if the greenhouse gasses were not present:

• There would be no change

• The average temperature on Earth would decrease by ~thirty (30) degrees Celsius, far below freezing

• The average temperature on Earth would increase by ~thirty (30) degress Celsius

• The Average temperature on Earth would be far too hot for any life to exist

How does the change in carbon dioxide over the last two hundred (200) years impact the climate on Earth.

• Carbon dioxide has no impact on climate.

• An increase in carbon dioxide leads to greater absorption of energy from the Earth, warming the atmosphere.

• An increase in carbon dioxide leads to greater reflection of energy from the Sun, cooling the atmosphere.

Describe the change in carbon dioxide levels over the last 200 years:

• There is no significant change in carbon dioxide over the last 200 years.
• There is a significant increase in carbon dioxide over the last 200 years.
• There is a significant decrease in carbon dioxide over the last 200 years.

The main human activity that releases greenhouse gases is

• using bottled water
• burning fossil fuels
• texting on cellphones
• eating meat

Why is the increase of Greenhouse gasses a big issue?

• It causes climate change and increase in the global temerature 
• It can lead to a major increase in Greenhouses 
• It leads to more factories
• It causes a major decrease in people

Why does cutting down trees increase global warming?

• trees soak up carbon dioxide
• trees provide shade which counteracts global warming
• trees absorbs the sun's energy without radiating back into the atmosphere
• trees drain greenhouse gases like methane from soil

Carbon is used by plants during which process?

• Respiration
• Transpiration
• Photosynthesis
• Transportation
