What are greenhouse gases?

• Gases that keep heat trapped in the atmosphere.

• Gases that are in the presence of plants, which is why they are called greenhouse gases.

• Gases such as liquid water and glucose.

• Gases that are emitted (released) from ocean water.

What is the purpose of the greenhouse effect?

• Earth's energy can bounce off the surface of Earth

• The energy from the sun can go back into space since it is too hot for Earth.

• Keeps some of the heat and energy from the sun trapped within the atmosphere of Earth.

• Allows Earth to rotate around the sun.

Throughout the years, there is evidence of a changing climate because... (SELECT ALL THAT APPLY)

• Glaciers and sea ice have melted.

• There is an increase in overall global temperature.

• Sea levels have risen contributing to the loss of land.

• There is less CO₂ present in the atmosphere now compared to 10 years ago.

Which of these are reasons why there is an increase in sea levels? Check all that apply.

• Melting of ice caps and glaciers add water to the oceans.

• The presence of greenhouse gases in the ocean cause sea levels to rise.

• In warmer temperatures, thermal expansion of water molecules occurs.

• When temperatures increase, carbon dioxide levels in the atmosphere decrease.
