When making an argument about how climate change is affecting the ice cover on Earth, which of the following would be the least effective type of evidence to support your argument?
a) data tracking the amount of snowfall for the last 50 years
b) data tracking the surface temperature for the last 200 years
c) data tracking carbon dioxide levels for the last 100 years
d) data tracking glacier size for the last 2 years

What can humans do 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 one reason that carbon dioxide is increasing in the atmosphere today?
a) There are more volcanoes than there were in the past.
b) People are riding bicycles instead of driving cars
c) There are more people doing things that use combustion.
d) People are using solar power.

Scientists who study the atmosphere often need to take samples of the atmosphere in order to learn more. They take some atmosphere samples near the ground. They take other atmosphere samples high in the air, while flying in a helicopter. What would t
a) Both samples are made of one kind of gas.
b) Both samples are made of a mix of several different kinds of gases.
c) Neither sample is made of anything.
d) The samples are different from each other because each gas forms its own layer in the atmosphere.

Using evidence from rocks, scientists have found that from 300 to 290 million years ago, the amount of methane in the atmosphere increased. What happened to the energy absorbed by Earth's surface during this time?
a) stayed at a constant level.
b) changed unpredictably.
c) increased.
d) decreased.

Scientists are using a computer simulation to test ideas about climate on Earth. Looking at one period of time in the simulation, they notice that more energy entered the Earth system than exited. How might the amount of carbon dioxide have changed t
a) carbon dioxide decreased, leading to more energy in the Earth system and more energy absorbed by Earth’s surface.
b) carbon dioxide decreased, leading to less energy in the Earth system and less energy absorbed by Earth’s surface.
c) carbon dioxide increased, leading to less energy in the Earth system and less energy absorbed by Earth’s surface.
d) carbon dioxide increased, leading to more energy in the Earth system and more energy absorbed by Earth’s surface.

What happens when energy hits sulfur dioxide?
a) When energy hits sulfur dioxide, more energy is created.
b) Sulfur dioxide traps some energy and holds it in the atmosphere.
c) Sulfur dioxide redirects (bounces) some incoming energy from the sun back toward outer space.
d) Energy always passes through sulfur dioxide.

The Karoo Ice Age started about 360 million years ago and lasted for about 40 million years. During this time, less energy entered the Earth system than exited. What is one change to the atmosphere that could have caused this?
a) Carbon dioxide decreased, leading to less energy in the Earth system because less energy was trapped by gases and held in the
b) Carbon dioxide decreased, leading to less energy in the Earth system because less exiting energy was redirected (bounced) bac
c) Carbon dioxide increased, leading to more energy in the Earth system because more exiting energy was redirected (bounced) bac
d) Carbon dioxide increased, leading to less energy in the Earth system because more energy from the sun was redirected (bounced

When carbon dioxide in the atmosphere increases, the amount of energy absorbed by Earth’s surface should...
a) increase
b) decrease
c) stay at a constant level
d) change unpredictably

Scientists found evidence of a time period 3 billion years ago when less energy entered the Earth system than exited. What is one change to the atmosphere that could have caused this, and how did it change the amount of energy in the Earth system?
a) Methane increased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.
b) Methane increased, leading to less energy in the Earth system and less energy absorbed by Earth's surface.
c) Methane decreased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.
d) Methane decreased, leading to less energy in the Earth system and less energy absorbed by Earth's surface.

If energy entering the Earth system is LESS than the energy leaving then the global temperature will _________.
a) increase
b) decrease
c) stay the same
d) go up and down like crazy

If the relationship between energy entering and energy leaving is stable, what is happening to the global temperature.
a) it is increasing
b) it is decreasing
c) it is staying about the same
d) it is going up and down like crazy

Changes in the global temperature have happened throughout Earth's history. Why are we so worried about the change in global temperature this time?
a) because we like cooler temperatures
b) because it's too hot at the equator already
c) because we believe that human activity is the cause
d) because we all like winter the best anyway

If energy entering the Earth system is GREATER than the energy leaving then the global temperature will _________.
a) increase
b) decrease
c) stay the same
d) go up and down like crazy
