Local and Global Change Agents

Why are too many greenhouse gases bad for the environment?

• They cause trees to die.

• They release heat and will be the cause of the next ice age.

• They trap heat in our atmosphere causing the planet to warm up.

• They are fossil fuels which pollute our environment.

Cloud cover is an example of which greenhouse gas?

• water vapor

• methane

• carbon dioxide

• flouride

Oil, gasoline and coal are all examples of this type of fuel.

• natural gases

• fossil fuels

• alternative fuels

• bio-fuels

Choose all of the following that are alternative (greener) energy sources...

• The sun

• Wind

• Electricity

• Water

What is global warming?

• a gradual increase in the overall temperature of the earth's atmosphere.

• a change in global or regional climate patterns

• the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land.

• The action of clearing a wide area of trees.

What is climate change?

• The trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.

• a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, and other pollutants.

• The action of clearing a wide area of trees.

• a change in global or regional climate patterns, in particular a change attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.

Which of these is considered a non renewable energy source? (choose all that apply)

• solar power

• gasoline

• geothermal power

• coal

Which of these is a consequence of global warming to our oceans? (choose all that apply)

• Acidification: Ocean is becoming more acidic.

• Sea level is rising due to land ice melting.

• Coral bleaching which results in them dying.

• Animals are getting strangled by plastic 6 pack rings.

Some greenhouse gases are naturally present in the Earth's atmosphere

• True
• False

Carbon is stored in

• Trees and other living things
• Oceans
• underground in soil and fossil fuels
• All are correct
