Front

Global warming is:

Back

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

Front

What evidence do we have that global temperatures are rising and climates are changing? Options: Global temperature data, Evidence of glaciers and ice-caps melting, Sea-level data (satellite and tidal), Various biological responses in ecosystems

All of the above

Front

Which of the following correctly differentiates between weather and climate?

Back

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

Front

Which process accurately describes the cause of the greenhouse effect? Options: 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.

Back

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

Front

Increased carbon dioxide may cause global warming by

Back

trapping more heat in the atmosphere.
