Climate Change - Causes Quiz

Greenhouse gases include (select 3):

• Carbon dioxide (CO2)

• Methane (CH4)

• Bicarbonate (HCO3)

• Nitrous Oxide (N2O)

Why is the concentration of these gases increasing?

• Increase in global forest cover

• Human activity

• Increase in the use of solar panels

• Decrease in gas powered vehicles

Which of the following answer choices best explains the greenhouse effect?

• Greenhouse gases trap all heat from the sun, keep Earth at a livable temperature

• Greenhouse gases prevent the entry of some light from the sun, causing an overall cool climate on Earth

• Greenhouse gases reflect all light from the sun, causing Earth's temperature to drop globally

• Greenhouse gases trap heat that tries to escape Earth's atmosphere, warming the Earth

Coal, oil, & natural gas come from:

• Fossil fuels

• Trees

• Ocean vents

• Volcanoes

In regards to climate change, sea ice melting is harmful because:

• The dark oceans underneath are revealed and absorb more sunlight, warming the Earth

• The oceans will reflect back more sunlight than the ice, reversing the current trend and leading to global cooling

• Additional almost-freezing water is added to the oceans, disrupting ocean currents and lowering ocean temperatures

• Possible diseases trapped in the ice may become free to infect the current global population

What is reflectivity?

• Dark colored objects (like the ocean, blacktop, etc) reflect the sun's light back into the atmosphere

• Dark colored objects (like the ocean, blacktop, etc) absorb the sun's light, removing it from the atmosphere

• Light colored objects (like clouds, snow, and sea ice) reflect the sun's light back into the atmosphere

• Light colored objects (like clouds, snow, and sea ice) absorb the sun's light, removing it from the atmosphere

The image below depicts the loss of sea ice over time, as well as the loss of sea ice in the future. How will the loss of sea ice further affect climate change? (Select 2)

• Less ice will be available to reflect the sun's rays, leading to increased global warming

• Less ice will be available to absorb the sun's rays, leading to widespread global cooling

• More dark ocean water will be exposed, which will reflect more sunlight and lead to global cooling

• More dark ocean water will be exposed, which will absorb more sunlight and lead to more global warming

Which answer choice best explains why methane is still a large concern?

• Methane accounts for 85% of greenhouse gases in the atmosphere

• Methane is 30 times more harmful than carbon dioxide (CO2)

• Methane can be pulled from the atmosphere by trees, unlike CO2

• Methane contains twice as much carbon as CO2

What role do livestock play in climate change?

• Domestic livestock produce large amounts of carbon dioxide (CO2) as part of their normal digestive process

• Domestic livestock produce an unmanageable amount of carbon dioxide (CO2) as part of normal respiration

• Domestic livestock produce an unmanageable amount of methane (CH4) as part of normal respiration

• Domestic livestock produce large amounts of methane (CH4) as part of their normal digestive process

Fertilizers increase agriculture production, and release a greenhouse gas called ____________.

• Carbon dioxide (CO2)

• Nitrous oxide (N2O)

• Methane (CH4)

• Bicarbonate (HCO3)
