Basic
What are greenhouse gases?
Gases that trap heat in the atmosphere.
Acceptable answer: Blanket
Which activity releases more carbon dioxide?
Breathing or Flying on airplanes?
Flying on Airplanes
What is the increase in Earth's temperature called?
Global warming
Name one renewable energy source.
Solar/Wind Energy
What happens when greenhouse gases trap heat?
Earth becomes warmer
Name one greenhouse gas
Carbon dioxide - CO2
Methane - CH4
Water vapour - H2O
What is the process called when coal, oil, natural gas is combusted to produce energy?
Burning fossil fuels
What happens to glaciers when Earth gets warmer?
They melt
Can protecting forests contribute to climate change? Give your reason.
Trees from forests absorb carbon dioxide and habitat for other living things
Burning fossil fuels
Why are greenhouse gases important for Earth?
Hint: Think about Mercury
The combustion of fuels produces gases like carbon dioxide into the atmosphere.
How can melting ice affect oceans?
It can cause sea levels to rise
Name ways people can reduce greenhouse gas emissions.
Use public transport, save electricity, recycle, plant trees
Explain the link between greenhouse gases and extreme weather patterns.
More trapped heat can cause extreme changes in weather patterns
Explain why too many greenhouse gases can be harmful
They trap extra heat, causing global temperatures to rise
How can using renewable energy instead of fossil fuels help reduce the over emission of greenhouse gas
Renewable energy produces fewer greenhouse emissions
How can planting more trees help reduce the effects of increased greenhouse gases?
Trees absorb carbon dioxide from the atmosphere
What would happen if the greenhouse gases doubled? Predict the effects and explain the chain reaction
More heat trapped -> global temperatures would rise -> ice caps melt -> sea levels rise -> weather/habitat changes
