Greenhouse Basics
What is the layer of gases surrounding Earth called?
What is Atmosphere?
This greenhouse gas is released when fossil fuels are burned.
What is carbon dioxide (CO₂)?
This is where most of Earth’s heat energy comes from.
What is the Sun?
This is one human activity that increases greenhouse gases.
What is burning fossil fuels / driving cars / running factories?
Greenhouse gases let sunlight in but trap heat.
What is true?
What role do greenhouse gases play in regulating Earth’s temperature?
What is they trap heat and warm the surface of Earth.
This greenhouse gas comes from cows, landfills, and wetlands.
What is methane (CH₄)?
This is where heat would escape if greenhouse gases were not present.
What is space?
This greenhouse gas is released during deforestation.
What is carbon dioxide?
Increasing greenhouse gases can cause climate change.
What is true?
What is the process called when gases trap heat and warm Earth?
What is the Greenhouse Effect
This is the most common greenhouse gas in Earth’s atmosphere.
What is water vapor?
What happens to Earth’s temperature when greenhouse gases increase.
What is the Earth gets warmer?
This is how many power plants produce energy that adds greenhouse gases to the atmosphere.
What is by burning coal, oil, or natural gas?
Only humans produce greenhouse gases.
What is false?
Why is the greenhouse effect important for life on Earth?
What is it keeps Earth warm by trapping heat
This gas is often confused as a greenhouse gas but is not one.
What is oxygen?
This common household item is often used to describe how greenhouse gases work.
What is a blanket?
This is one action humans can take to reduce greenhouse gas emissions.
What is using renewable energy, planting trees, or driving less?
Greenhouse effect is always bad.
What is false?
What would most likely happen to Earth if there were no greenhouse gases at all?
What is Earth would be too cold to support most life?
Name 3 greenhouse gases we have discussed during this scope.
Methane, Carbon dioxide, and Water Vapor
What would likely be the consequence if Earth were to suddenly lose its greenhouse gases, such as carbon dioxide and water vapor, from the atmosphere?
What is Earth’s average surface temperature would decrease?
This explains how cutting down trees increases greenhouse gases in the atmosphere.
What is fewer trees absorb carbon dioxide, so more CO₂ stays in the air?
Water vapor is a greenhouse gas and human activities can affect its amount.
What is true?
