APES 9.4 - Increase in Greenhouse Gases

Nora, Abigail, and Priya are studying about the environment. They came across a term 'greenhouse effect'. Can you help them understand what is the greenhouse effect?

• It is the process of solar radiation being reflected back into space

• It is the trapping of heat by gases in Earth's atmosphere

• It is the absorption of infrared radiation by water vapor

• It is the emission of visible light by greenhouse gases

Abigail, David, and Michael are studying the impact of different gases on the environment. They came across several gases like Carbon Dioxide (CO2), Methane (CH4), Oxygen (O2), and Nitrous Oxide (N2O). They found out that most of these gases are greenhouse gases. Can you help them identify which of the following is NOT a greenhouse gas?

• Carbon Dioxide (CO2)

• Methane (CH4)

• Oxygen (O2)

• Nitrous Oxide (N2O)

Oliver, Abigail, and Avery are discussing about the environment. They are trying to identify the main source of carbon dioxide emissions. Oliver thinks it's due to burning fossil fuels. What do you think?

• Burning fossil fuels

• Anaerobic decomposition

• Deforestation

• Natural gas extraction
