Earth's Changing Climate

QuestionAnswer
General weather patterns over a long period of time. Climate (1.2)
Variations in a set of data. Fluctuation (1.2)
The ability to make things move or change. Energy (1.3)
To take in. Absorb (1.3)
A molecule made of carbon and oxygen. Carbon Dioxide (1.5)
The process of burning fuels, which produces carbon dioxide. Combustion (3.1)
Changes in climate over a long period of time that can be caused by natural events or human activities. Climate Change (1.2)
Overall tendency (for example, a consistent increase) in a set of data over time. Trend (1.2)
A measure of how hot or cold something is. Temperature (1.3)
The mixture of gases surrounding a planet. Atmosphere (1.4)
A molecule made of carbon and hydrogen atoms. Methane (1.5)
Key Concept 1: Since ___________, there is a trend of increasing _____________ and decreasing _____________ on Earth. 1. 1880 ; 2. Temperatures ; 3. Ice
Key Concept 2: Global average temperature ___________ when energy ___________ by the surface increases. 1. Increases ; 2. Absorbed
Key Concept 3: When the amount of ______________ or ______________ in the atmosphere changes, the amount of energy ______________ by the surface also changes. 1. Carbon Dioxide ; 2. Methane ; 3. Absorbed
Key Concept 8: Temperature increases if ______________ energy enters than exits. 1. More
Key Concept 9: Temperature ______________ if less energy enters than exits. 1. Decreases
Key Concept 10: If there is an ______________ in the amount of carbon dioxide or methane the amount of energy leaving the Earth system ______________, so ______________ energy enters than exits. 1. Increase ; 2. Decreases ; 3. More
Key Concept 11: If there is a ______________ in the amount of carbon dioxide or methane the amount of energy leaving the Earth system ______________, so ______________ energy enters than exits. 1. Decrease ; 2. Increases ; 3. Less
Key Concept 12: Carbon dioxide and methane stop energy from ______________ by _________________ energy that would have ____________ the system. 1. Leaving ; 2. Redirecting ; 3. Exited
Key Concept 13: Carbon dioxide and methane in the atmosphere increase as a result of ________________________, such as ______________________. 1. Human activities ; 2. Combustion
Key Concept 14: Some ways to stop the increase of carbon dioxide and methane include _____________________ _________________ and ____________________ these gases from the ______________________. 1. Decreasing ; 2. Combustion ; 3. Removing ; 4. Atmosphere
Key Concept 15: Humans can take actions in their daily lives that will reduce that amount of ___________________ and ___________________ in the ___________________ . 1. Carbon dioxide ; 2. Methane ; 3. Atmosphere
If more energy is absorbed by the surface, what is happening to carbon dioxide or methane in the atmosphere? Carbon dioxide or methane are increasing in the atmosphere
If the global average temperature of Earth is increasing, is more energy entering the atmosphere OR is more energy exiting the atmosphere? More energy is entering the atmosphere
If there is a decrease in carbon dioxide or methane, will more energy enter or will more energy exit the atmosphere? More energy will exit the atmosphere
Why are carbon dioxide and methane increasing in the atmosphere? Combustion from cars/power plants/ methane emitted from livestock
If less energy is absorbed by the surface, what is happening to carbon dioxide or methane in the atmosphere? Carbon dioxide or methane are decreasing in the atmosphere
If more energy is entering than exiting, what is happening to carbon dioxide or methane in the atmosphere? Carbon dioxide or methane are increasing in the atmosphere
If less energy is entering than exiting, what is happening to carbon dioxide or methane in the atmosphere? Carbon dioxide or methane are decreasing in the atmosphere

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
