​

​The arrows show how heat is radiated back into the atmosphere by some gases.

Multiple Choice

What is the process of heat being radiated back into the atmosphere called?

• radiation

• depletion of ozone

• greenhouse effect

• condensation

​

​Factories artificially increase carbon dioxide levels due to the burning of fossil fuels such as coal and petroleum.

Processes such as respiration and factory emissions put carbon dioxide into the atmosphere.​

​

Multiple Choice

Which process will increase the levels of CO2 in the atmosphere?

• cellular respiration by plants and animals

• Factory emissions

• Photosynthesis

• Sunlight

​What do you notice about the amount of fuel used in the last two years on the graph? What inference might you make about cars during that time?

​

​Look at the information in the graph.

​

Multiple Choice

If cars and factories continue to increase in their use of fossil fuels such as petroleum products (gasoline) or coal, what conclusion could be made based on scientific data such as the previous graph?

• Temperatures will continue to increase due to a rise in CO2.

• Temperatures will decrease due to a rise in CO2.

• Temperatures will remain stable.

• Temperatures will disappear.

Fill in the Blank

The most abundant gas in the atmosphere is __________. Then __________ and __________. Trace gases, including carbon __________ are last.

Draw

Draw an arrow to show the movement of carbon dioxide in the ecosystem. Hint: In this photo, we see water, sunlight and the atmosphere.

Multiple Select

Greenhouse gases include which of the following? (multiple answers)

• methane

• water vapor

• oxygen

• carbon dioxide

Multiple Choice

What is wrong with this photo?

• There is too much nitrogen and too little Argon.

• There is too much Argon and too little Oxygen.

• There is too much Carbon Dioxide and too little Nitrogen.

• There is too much Carbon Dioxied and too little Oxygen.

Multiple Choice

Which gases do volcanoes put into the atmosphere?

• oxygen and methane

• nitrogen and chlorine

• water vapor and carbon dioxide

• carbon dioxide and sulfur

Multiple Choice

If we were to suddenly have twice as many trees on the planet as we do now, what do you hypothesize might happen?

• oxygen levels would decrease due to more photosynthesis

• oxygen levels would stay the same

• carbon dioxide would decrease due to more photosynthesis

• carbon dioxide would increase due to trees using up all the water
