Climate Change

Climate change causes extreme weather conditions such as:

• excessive heat
• drought
• extreme storms
• all of these

Which of the following is an example of a mitigation strategy?

• using renewable resources
• using non-emissions energy sources
• using energy efficient products
• all of them

Scientists predict that the hurricanes coming off the warming waters of the Gulf of Mexico will be less severe and less frequent.

• True
• False

If Earth did not have an atmosphere, most of the energy from the sun would 

• be reflected back into space.
• be absorbed by Earth’s oceans.
• be absorbed by Earth’s landmasses.
• never reach Earth’s surface.

Global warming refers specifically to an increase in 

• the number of storms on Earth.
• precipitation from Earth’s atmosphere.
• temperatures everywhere on Earth.
• Earth’s average surface temperature.

As a result of global warming, some plant species in the mountains of California have 

• shifted their locations higher into the mountains.
• developed shorter root systems.
• increased the amount of area they cover.
• become extinct.

What is the biggest danger posed by global warming to people living in coastal areas?

• increased precipitation
• increased acidity of sea water
• lack of carbon dioxide in the atmosphere
• rising sea level

How can the planting of new trees help reduce climate change?

• Trees help create breezes.
• Trees release moisture that cools the atmosphere.
• Trees take in carbon dioxide from the atmosphere during photosynthesis.
• Trees block the release of greenhouse gases from soil.

How do volcanic eruptions affect weather?

• Eruptions form clouds that drop large amounts of precipitation.
• Gases and particles may block sunlight and lower temperatures.
• Vibrations caused by eruptions shift ocean currents, which in turn affect weather.
• They cause a long-term increase in temperature.

Which human activity contributes the most carbon dioxide to the atmosphere?

• fishing
• breathing
• burning fossil fuels
• farming
