What are greenhouse gases and how do they contribute to the greenhouse effect?

• Gases that absorb water vapour

• Gases that prevent sunlight from reaching the Earth

• Gases that cool the Earth's atmosphere

What is the primary source of carbon dioxide emissions into the atmosphere?

• Decomposition of organic waste

• Combustion of fossil fuels

• Evaporation and condensation

• Photosynthesis in plants

What is the process known as outgassing in relation to carbon dioxide?

• Conversion of CO2 into oxygen

• Trapping of CO2 in glaciers

• Absorption of CO2 by ocean water

• Release of stored CO2 from the ocean due to rising temperatures
