Refresher Vocabulary
An object, diagram, or computer program that helps us understand something by making it simpler or easier to see
What is a Model?
If more energy was entering earth's system than leaving, this would happen to the global average temperature
What is an increase?
An overall tendency (for example, a consistent increase) in a set of data over time
What is a trend?
When carbon dioxide in the atmosphere increases, the amount of energy absorbed by Earth’s surface should do this:
A. increase B decrease C. stay at a constant level or D. change unpredictably
What is
A. / Increase
Changes in climate over a long period of time that can be caused by natural events or human activities
What is Climate Change?
The ability to make things move or change
What is Energy?
If less energy was entering earth's system than leaving, this would happen to the global average temperature
What is a decrease?
Variations in a set of data
What are fluctuations?
The global temperature increases when there is more of this energy type redirected towards the earth by greenhouse gasses.
What is thermal energy/heat?
To take in
What is to absorb?
Conditions such as rain, clouds, and wind at a particular time and place
What is Weather
If the same amount energy was entering earth's system and leaving, this would happen to the global average temperature
What is to stay the same?
As an example: A small volcanic eruption caused a cloud to reflect light away from the earth, and temporarily caused a cooler average global temperature for just that year.
What is a fluctuation?
This type of energy can move past greenhouse gasses without being affected by them
What is solar energy?
Two greenhouse gasses
What are carbon dioxide and methane?
General weather patterns over a long period of time
What is Climate?
Currently, there is _____ energy entering earth's system than leaving
What is more?
As an example, the global average temperature is warmer for two years, colder for three, warmer for four, colder for two.
What are fluctuations
Humans can do this to help keep carbon dioxide and methane in Earth’s atmosphere from increasing
A. Drive their cars less often
B. Eat less meat so that fewer livestock need to be kept
C. Both A and B
D. Humans can't affect the amount of carbon dioxide or methane in the atmosphere
What is
C
The process of burning fuels, which produces carbon dioxide
What is combustion?
The mixture of gases surrounding a planet
What is the Atmosphere?
During an ice age, it is likely that there is ________ energy entering than leaving
What is less?
As an example: Even though the average global temperature has been rising and falling since the beginning of Earth's existence, human activity has caused it to rise quickly and uncontrollably. Some years it cools down a little bit, but the overall pattern is a warming climate.
What is a trend?
When there is an increase in methane or carbon dioxide in the atmosphere, the earth system's overall energy increases. This because of this thing that thermal energy does, when it encounters a greenhouse gas
What is the act of reflecting/redirecting back towards earth?
Things people do that affect the Earth system
What are human activities?
