GREENHOUSE EFFECT
What is the most common greenhouse gas
Co2
Which greenhouse gas is CO2?
Carbon Dioxide
TRUE OR FALSE? The Earth is nothing like a greenhouse.
False
What happens to the sun's energy when it reaches Earth's surface?
It is absorbed and re-reradiated as infrared (heat) energy
How does the greenhouse effect affect our planet
It heats up the earth
Which greenhouse gas is H2O?
Water Vapour
TRUE OR FALSE? The temperature change on Earth are due to the greenhouse effect.
True
How do trees or plants help us balance out greenhouse gases?
They take in (absorb) carbon dioxide when they do phosynthesis- storing the carbon inside as they make sugar and release oxygen
What are natural sources of greenhouse gases?
animal respiration, ocean/gas exchange, volcano eruptions, decomposition
Which greenhouse gas is NH4?
Methane
TRUE OR FALSE? More greenhouse gases in the atmosphere means a cooler temperature
False
What type of radiation is absorbed by greenhouse gases?
infrared radiation
Draw the greenhouse effect!

4. GHG
Name 3 of the 5 main greenhouse gases.
Carbon Dioxide (CO2)
Methane (CH4)
Water Vapor
Ozone (O3)
CFCs
Greenhouse gases act like a __________ around the Earth, trapping the heat from the sun.
"blanket"
How does the grenhouse effect benefit life on Earth?
It keeps the Earth's temperature at a habitable level, without it Earth would be too cold for life.
WHICH human activities contribute to the greenhouse effect? (Give an example)
Burning coal, oil, natural gases, farming, deforestation, factories...
What are unnatural (human) sources of carbon dioxide?
burning fossil fuels, deforestation, industry
When can greenhouse gases be harmful to living beings on Earth?
When there's too much of them in the atmosphere.
3 ways to reduce greenhouse gas emissions include:
Transportation: Using public transportation, walking, taking fewer trips, carpooling
Eating less meat
Using renewable energy sources such as solar, wind, hydroelectric instead of fossil fuels (coal, gas)
Reducing energy loss or waste (turning off lights/electronics, better insulation)
Energy efficiency (more efficient appliances)
