Based on the graph, what can you predict will happen in the future?
As CO2 levels increase, temperatures will continue to rise
CO2 levels have nothing to do with temperature
Temperatures will decrease as CO2 levels increase
CO2 levels will decrease and temperatures will increase.
As temperatures rise, animals will react to the change:
Having more offspring
Changing their normal patterns north or south to remain where temperatures are the same
Eating more food
Animals will not react to the temperature change
What is the main cause of the greenhouse effect?
The gases in the atmosphere absorb the Sun's heat.
The gases in the atmosphere absorb the Earth's surface heat.
The gases in the ozone layer absorb the Sun's heat.

If human civilization had never developed on Earth, would there be a greenhouse effect?
Yes, the greenhouse effect is caused by naturally occurring gases.
Yes, the greenhouse effect is caused by plants emitting gases.
No, the greenhouse effect is caused by humans burning fossil fuels.
No, the greenhouse effect is caused by humans depleting the ozone.
No, there is no conclusive evidence that a greenhouse effect exists.
What are greenhouse gases?
Gases in the atmosphere that are produced as plants grow.
Gases on the surface of the earth that absorb energy.
Gases in the atmosphere that make rain turn acidic.
Gases in the atmosphere that absorb energy (heat)
Currently, the concentration of carbon dioxide in Earth's atmosphere is approximately 400 parts per million. During the Cretaceous period, about 110 million years ago, the concentration of carbon dioxide in Earth's atmosphere was approximately 2,000 parts per million.
Based on your knowledge of the greenhouse effect, how do you think the average temperature on Earth 110 million years ago compared to the temperature in modern times?
Temperatures were warmer 110 million years ago than in modern times.
Temperatures were cooler 110 million years ago than in modern times.
Temperatures 110 million years ago were approximately the same as in modern times.
More information is needed to answer this question.
Currently, the concentration of carbon dioxide in the Earth's atmosphere is approximately 400 parts per million. During the Pleistocene, about 150 thousand years ago, the concentration of carbon dioxide in the Earth's atmosphere was approximately 200 parts per million.
Based on your knowledge of the greenhouse effect, how do you think the average temperature on Earth during the Pleistocene compared to the temperature in modern times?
Temperatures were warmer 150 thousand years ago than in modern times.
Temperatures were colder 150 thousand years ago than in modern times.
Temperatures 150 thousand years ago were approximately the same as in modern times.

How does global warming affect sea levels?
Marine animals are taking up more space causing sea levels to rise.
The heated atmosphere causes glaciers and ice sheets to melt, causing sea levels to rise.
More water is being consumed by people.
