Question | Answer |

What is Carbon dioxide? | A molecule made of carbon and oxygen atoms. |
What is Climate? | General weather patterns over a long period of time. |
What is Climate Change? | Changes in climate over a long period of time that can be caused by natural events or human activities. |
What is Combustion? | The process of burning fuels, which produces carbon dioxide. |
What is Fluctuation? | Variations in a set of data. |
What is Methane? | A molecule made of carbon and hydrogen atoms. |
What is Trend? | Overall tendancy in a set of data overtime. |
Although there are many fluctuations, there is a trend toward _______ temperatures and decreasing ________ on earth since about ______. | Increasing, ice, 1880 |
Global average temperature __________ when __________ absorbed by the surface increases. | Increases, energy |
When the amount of __________ or __________ in the atmosphere changes, the amount of __________ absorbed by the __________ also changes. | Carbon dioxide, Methane, energy, surface |
When the amount of carbon dioxide or methane __________, __________ absorbed by the surface increases. | Increases, energy |
When the amount of ___________ or ___________ decreases, energy absorbed by the surface __________. | Carbon dioxide, Methane, decreases. |
A change to either the amount of energy __________ or __________ the earth system affects how much energy is absorbed by the surface. | Entering, exiting |
Temperature increases if __________ energy enters then exits. | More |
Temperature decreases if __________ energy enters then exits. | Less |
If there is an __________ in the amount of carbon dioxide or methane, the amount of energy leaving the earth system __________, so more energy enters than exits. | Increase, decrease |
If there is an __________ in the amount of carbon dioxide or methane, the amount of energy leaving the earth system increases, so __________ energy enters than exits. | Decrease, less |
Carbon dioxide and Methane __________ energy from leaving by __________ energy that would have exited the system. | Stop, redirecting |
Carbon dioxide and Methane in the atmosphere __________ as a result of human activities, such as __________. | Increase, combustion |
Some ways to __________ the increase of carbon dioxide and Methane include decreasing __________ and removing these gases from the atmosphere. | Stop, combustion |
What is more reliable and why: Fluctuations or Trends? | Trends because they go for a longer period of time. |
What gasses affect energy and how? | If carbon dioxide or methane increases, there will be an increase in energy. If there is a increase in sulfur dioxide, energy will decrease. Nitrogen dioxide does not affect energy. |
What gasses are increasing in the atmosphere and why? | Carbon dioxide and Methane are increasing because of combustion, deforestation and a cows diet. |
How can we reduce these gasses. | Planting more trees, (Reforestation) not using cars or automobiles as much or changes in a cows diet so it does not belch or release gas as much. |
How does Combustion affect the total amount of energy in Earths system? | Combustion releases carbon dioxide when being used. More combustion, more carbon dioxide. If there is more carbon dioxide, there will be more energy. |
How does Carbon dioxide increase energy? | More energy is going to enter than exit the earth's atmosphere because the energy that is trying to exit will get redirected back to Earth. |
How does this affect Global average temperature? | If there is more energy because of the more combustion, there will be a higher temperature. |
What is energy? | The ability to make things move or change. |
What is temperature? | A measure of how hot or cold something is. |
What is absorb? | To take in. |
What is atmosphere? | The mixture of gases surrounding a planet. |
What is Model? | An object, diagram, or computer program that helps us understand something by making it simpler or easier to see. |
What are Human Activities? | Things people do that affect the earth's system. |
What is stability? | When something stays mostly the same over time? |
What is change? | When something becomes different over time? |
What is sulfur dioxide? | A molecule made of sulfur and oxygen atoms. |
