Climate Change I
What gas, made from burning oil and coal, warms the Earth?
carbon dioxide
Are extreme weather events becoming more or less frequent as air temperatures increase?
More frequent
Planting these helps take in CO2 and fight climate change.
trees
This term means the Earth is getting warmer because of human actions.
Global warming
Raising this type of animal produces a lot of methane gas.
cows
Rising temperatures cause this problem for coastal areas.
Rise in sea levels
Type of transport that does not use fossil fuels. They are becoming increasingly popular.
electric vehicles
The process of atmospheric gases trapping heat in the Earth's environment.
Greenhouse effect
Describe the trend in temperature around the world
Increased average global temperature
Identify two areas/biomes/structures of frozen water that are being affected by rising global temperatures.
E.g. Arctic, Antarctic, Glaciers, Permafrost
Describe the energy transformation that occurs in wind power generators
(ie. starting energy type -> converted energy type)
Kinetic energy -> Electrical energy
This means cutting down trees for farming or building.
Deforestation
Main energy source used by people in the last 200 years that contributes to an increased greenhouse effect
Fossil fuels (oil, coal, gas)
What is the name of the largest forest in the world that helps clean the air and is at risk due to climate change?
Amazon rainforest
This class of products, used to kill pests, also causes water pollution
pesticides
This term refers to a sustained period lacking in rainfall and other natural water supply
Drought
How does deforestation and other forms of cutting down trees affect the atmosphere?
Less oxygen produced, less CO2 absorbed
Coral reefs in the the oceans are in danger because of this phenomenon.
ocean acidification/increased pH levels
Using fewer resources and cutting down on waste is called...
S_______________
sustainability
Explain the difference between weather and climate.
Climate refers to long-term patterns in environmental conditions, whereas weather is short-term events (eg. daily rainfall).
