Greenhouse Gases
Which organisms are affected by air pollution?
(Plants, Mammals, Birds, Humans, or All of the above)
All organisms are affected by air pollutions!
Rising global temperatures can affect which of the following:
(Ocean and sea ice levels, food resource availability, more frequent wildfires, or All of the above)
Rising global temperatures affect all of the above. It causes ocean levels to rise, polar ice to melt, reduces food resources and causes more frequent wildfires)
List three kinds of renewable energy sources.
Solar, wind, geothermal, hydroelectric, biofuels.
Name the three most common Greenhouse Gases.
The three main greenhouse gases are: Carbon Dioxide, Methane, Nitrous Oxide
How does the polar ice melting affect arctic animals?
They could die off because of habitat loss.
Nuclear energy is a "clean" energy source but not considered a renewable energy source. What is the "clean" energy source?
A clean energy source is one that does not produce greenhouse gases.
The temperature on the Earth has been rising for about the last 100 years. What event in human history might explain that?
The Industrial Revolution increased Greenhouse Gas emissions which contributes to climate change.
What type of air pollution can humans not control?
(Vehicle emissions, power plant emissions, volcanic emissions, all of the above)
Humans cannot control volcanic emissions.
Why is it so difficult to switch from fossil fuels to renewable energy sources?
Fossil fuels are bad for the environment but they produce a VERY high amount of energy which is difficult to replace.
Methane and Carbon Dioxide are both greenhouse gases. There is less Methane emissions compared to Carbon Dioxide, so why are we so concerned with Methane emissions?
Methane is much better at trapping heat in the atmosphere compared to Carbon Dioxide.
List one reasons why burning fossil fuels is bad for the environment and and one reason why it is unsustainable.
Burning fossil fuels releases Carbon Dioxide which is a greenhouse gas.
We will eventually run out of fossil fuels, making it unsustainable for the future.
Why do we consider wood/lumber to be a non-renewable resource?
Cattle produce methane. What percent of the methane in the atmosphere comes from cattle?
(15%, 30%, 50%, 90%)
What is something that YOU can do to reduce your carbon footprint?
Open ended answer.
What is one reason deforestation contributes to the increase in greenhouse gases?
Deforestation cuts down trees and trees absorb carbon dioxide to use for photosynthesis.
