/ 2
pts
What is true of positive feedbacks? Select all that apply.
they are generally beneficial for sustaining a system.
they lead to homeostasis.
Correct!
they amplify a disturbance to a system.
they dampen a disturbance to a system.
none of the above
Correct! Positive feedbacks act to amplify a disturbance to a system.
Question 2

/ 2
pts
Changes in reflectivity of visible light affect how much energy enters Earth's system. What term is used by scientists to describe the reflectivity of a surface? Select all that apply.
contrastivity
libido
Correct!
albedo
alluvium
mirror-effect
none of the above
Correct! Albedo refers to the amount of solar radiation reflected from an object or surface, often expressed as a percentage. Earth as a whole has an albedo of about 30%, meaning that 70% of the sunlight that reaches the planet is absorbed.
Question 3

/ 2
pts
What is the primary cause of ocean acidification? Select all that apply.
water draining into the ocean has a higher pH from industrial pollutants
increases in acid rain
increased erosion of acid-containing rocks
Correct!
atmospheric CO2 dissolving in ocean water
none of the above
Correct! Oceans become more acidic as carbon dioxide (CO2) emissions in the atmosphere dissolve in the ocean.
Question 4

/ 2
pts
Nitrous oxide is similar to methane in that both greenhouse gasses are _____.
Select all that apply.
Correct!
commonly produced through agricultural activities
more abundant in the atmosphere than carbon dioxide
far more potent than carbon dioxide
associated with strong odors
none of the above
Correct! Methane is produced through cattle production and in rice paddies, while nitrous oxide is released through fertilizer application to fields.
Question 5
2
/ 2
pts
Climate is _________. Select all that apply.
Correct!
a pattern of weather over a long period of time
the weather report for the day
the changing of weather throughout the day
none of the above
Correct! Climate is defined as long-term weather patterns, such as temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness. Weather is short-term weather patterns.

none of the above
Correct! Oxygen is not a greenhouse gas.
Question 7

/ 2
pts
What do greenhouse gasses do? Select all that apply.
they trap heat coming from the sun to the Earth.
Correct!
they trap heat the Earth is radiating back into space.
they destroy the ozone layer protecting us from the sun's heat.
they prevent cooler gasses in the stratosphere from reaching the Earth.
none of the above
Correct! Greenhouse gasses act like a blanket, trapping the heat that the Earth is radiating back into space.
Question 8
2
/ 2
pts
Which of the following contributes to climate? Select all that apply.
short-term patterns in temperature and precipitation
Correct!
long-term patterns in temperature and precipitation
temperature only
precipitation only
none of the above
Correct! Climate is defined as long-term weather patterns, such as temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness.
Question 9

/ 2
pts
Which one of the following is a predicted consequence of global climate change? Select all that apply.
Correct!
spread of diseases carried by insects, such as malaria
Correct!
rise in sea levels
Correct!
increases in the global average air and ocean temperatures
Correct!
intensity of precipitation events will likely increase on average.
none of the above
Correct! All are predicted consequences of global climate change.
Question 10

/ 2
pts
True or false: Climate change is heating the world evenly.
[true]
Correct!
[false]
Correct! Numerous hot spots have already exceeded the critical 2 degree Celsius (3.6 degree Fahrenheit) mark, far above the global average. In general, higher latitudes, such as the Arctic, are warming faster than mid-
latitude regions.
Question 11
2
/ 2
pts
True or false: Greenhouse gasses are necessary.
Correct!
[true]
[false]
Correct! The greenhouse effect is an essential environmental prerequisite for
life on Earth
Question 12

/ 2
pts
Climate determines _________. Select all that apply.
Correct!
the plants that are able to grow
Correct!
the animals that live in the area
if you should wear a sweater or coat for the day
none of the above
Correct! Climate is defined as long-term weather patterns, such as temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness. Weather is short-term weather patterns.
Question 13

there is no difference between the two terms.
global climate change is being caused by people, while the greenhouse effect is natural.
Correct!
the greenhouse effect only began with the Industrial Revolution, while global climate change began with the formation of the Earth.
none of the above
Correct! Global climate change is the term used to refer to human impacts on our atmosphere and climate since the Industrial Revolution, while the greenhouse effect is a natural process that has made the Earth warm enough
to support life.
Question 14

/ 2
pts
What is a carbon footprint? Select all that apply.
a footprint left behind by someone walking over black rock
a measure of how much heat you produce
a measure of how well you understand the carbon cycle
Correct!
a measure of how much carbon emissions you produce
none of the above
Correct! A carbon footprint serves as a measure of how much carbon emissions you produce through daily actions, such as driving to work or running a washer/dryer.
Question 15

/ 2
pts
Given that methane emissions were only 11% of all the greenhouse gas emitted by the United States in 2020, why should we be concerned about its increase? Select all that apply.
it remains in the atmosphere much longer than carbon dioxide.
it is far more abundant in the atmosphere than carbon dioxide.
unlike carbon dioxide, it also puts a terrible odor into the air.
it is far less effective at trapping heat than carbon dioxide.
Correct!
none of the above
Correct! Methane is 20 to 30 times more potent as a greenhouse gas than carbon dioxide.
