Which of the following is a greenhouse gas:

Water vapor

Carbon dioxide

Ozone

Nitrous oxide

All of the above

The greenhouse gas that has most contributed to climate change over the last 100 years is:

Ozone

Methane

Carbon Dioxide

Chlorofluorocarbons

Global warming is:

the long-term changes in climate, including average temperature and precipitation

the melting of the polar ice caps

the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere

sea-level rise

Which of the following correctly differentiates between weather and climate?

Weather describes short term conditions of the atmosphere, while climate describes long term conditions of the atmosphere.

Weather describes long term conditions of the atmosphere, while climate describes short term conditions of the atmosphere.

Weather describes conditions of the atmosphere, while climate only describes changes in temperature.

Weather describes changes in temperature over time, while climate describes changes in atmosphere over time.

Greenhouse gases:

Trap cold air in the atmosphere

Trap heat in the atmosphere

Have no positive effects

Play no role in global warming

Which process accurately describes the cause of the greenhouse effect?

The Sun's rays are reflected from the land back into the atmosphere.

Increased solar energy is entering through the hole in the ozone layer.

Aerosol gases become trapped and build up in the atmosphere.

Heat radiating from the land and oceans is trapped in the troposphere.

Which of these could lead to an increase average global temperatures?

increased use of fossil fuels

increased ocean plants

decreased carbon dioxide emissions

increased numbers of animal species

What are examples of renewable energy sources?

Solar

Wind

Coal

Gas

What is the direct cause of rising sea levels?
