Section 9-5: Canadian Emission of Greenhouse Gases

Exercise 1
Step 1
1 of 3
a) Car emissions, industrial processes, landfills, cow/animal farms, burning coal and natural gas to produce electricity, and deforestation.
Step 2
2 of 3
It should be a priority to reduce car emissions, lower industrial emissions, and stop deforestation because these are the easiest changes that have major impacts on reducing emissions
Result
3 of 3
a) Car emissions, industrial processes, landfills, cow/animal farms, burning coal and natural gas to produce electricity, and deforestation.
Exercise 2
Step 1
1 of 3
a) methane and nitrous oxide
Step 2
2 of 3
b) methane comes from cows and landfills, nitrous oxide comes from industrial waste.
Result
3 of 3
a) methane and nitrous oxide
Exercise 3
Step 1
1 of 3
a) it will increase the input since their will be less carbon sinks as the forests lose their ability to use carbon when attacked by fires or insects.
Step 2
2 of 3
b) it will further increase the contribution since burning anything releases carbon dioxide into the atmosphere
Result
3 of 3
a) it will increase the input since their will be less carbon sinks as the forests lose their ability to use carbon when attacked by fires or insects.
Exercise 4
Result
1 of 1
Growth of new trees creates carbon sinks. Insect infestations kill trees and release carbon dioxide similarly to wildfires
Exercise 5
Result
1 of 1
Carbon sinks reduce greenhouse gas emission, lowering temperatures or preventing them from further increasing
