Total questions: 20
Worksheet time: 10mins
What is a major source of air pollution?
planting more trees in a rain forest
the production of energy using solar and nuclear power
small farms raising large number of livestock (pigs, cows, chickens)
building a dam for hydroelectric power
What is the "Greenhouse Effect" and how does it relate to life on Earth?
it is the ability of gases in the atmosphere to trap heat and make Earth habitable.
it is how we grow food to eat
it is the idea that green plants provide food for humans
it is the effect that greenhouses have
How do plants affect carbon dioxide levels in the atmosphere?
They reduce the amount of atmospheric CO2
They increase the amount of CO2 in the atmosphere
Does not change the amount of atmospheric CO2
They cause humans to increase CO2 in their lungs.
Which of the following is an example of a greenhouse gas?
Oxygen
Nitrogen
Water vapor
Carbon Dioxide
True or False;
All of the radiation from the Sun is absorbed by the Earth.
True
False
Which of the following human activities do NOT contribute to the total amount of greenhouse gases in Earth's atmosphere?
raising cows
driving cars
heating homes
planting orchards
Which of the following is an example of how climate change could affect agriculture?
fewer pests and weeds
Mammoths will thaw from permafrost and eat all of the plants
Increased droughts could reduce the amount of water available for irrigation
Fewer storms - so more nice weather for planting and harvesting
The ozone layer protects us from
CFCs
Increased atmospheric heat
UV radiation
Decreased atmospheric heat
True or False: The Greenhouse Effect is naturally occurring and is required for life to exist on Earth
True
False
By decreasing our demand for meat that comes from cows, we can cut down on the emission of this greenhouse gas:
Carbon dioxide
Nitrous oxide
methane
water vapor
What limiting factor for a human population causes more deaths than births?
Disease
New technology & medicine
Increased food production
Vaccines
You are walking in the woods, and notice lots of lichen hanging on the trees. Lichen are a very sensitive plant (bioindicator), what can you assume about the air quality in the forest?
The air is likely very clean and not polluted
The air is very polluted
You can't tell anything about the air
Which of the following is NOT a result of climate change?
Severe storms
Droughts
Sea level rise
A new ice age
Which region of the world has the largest human population?
Europe
Asia
North America
South America
Which region of the world is likely to have the poorest air quality due to large human populations?
Canada
Antarctica
Iceland
China
Japan
Who is most affected by air pollution?
Professional swimmers
People with asthma/respiratory problems
Deep sea fish
People who live on farms
Which best explains how the greenhouse effect has caused a rise in global temperatures?
Increased production of carbon dioxide holds in heat and prevents it from escaping Earth's atmosphere.
CFCs used in aerosol sprays have decrease the levels of radiation that enter the Earth's atmosphere.
The thickening of the ozone layer has decreased the levels of UV radiation that reach the Earth's atmosphere.
The use of heating and cooling have produced increased levels of moisture in the air, which holds in heat.
What is the biggest danger posed by global warming to people living in coastal areas?
increased population
lack of carbon dioxide in the atmosphere
rising sea levels
increased acidity of sea water
The average temperature of Earth's atmosphere has warmed by approximately 1.8 degrees Fahrenheit over the past century. Which reason best explains why this has happened?
higher levels of carbon dioxide in the atmosphere
lower levels of ozone in the atmosphere
lower levels of nitrogen in the atmosphere
higher levels of oxygen in the atmosphere
What is air pollution?
industrial pollution
chemicals
any harmful substance that builds up in the air
pollen, dust and gases
