How do greenhouse gases contribute to the warming of the Earth's atmosphere?

A
The amount of greenhouse gases in the atmosphere causes a cooling of the atmosphere.
B
The more greenhouse gases in the atmosphere the less warming of the atmosphere.
C
The amount of greenhouse gases in the atmosphere has no effect on the warming of the atmosphere.
D
The more greenhouse gases in the atmosphere the more warming of the atmosphere.
3

Which accurately describes how human activities influence atmospheric conditions?

A
Humans using fertilizers release carbon dioxide into the atmosphere.
B
Humans burning fossil fuels release methane gas into the atmosphere.
C
Humans using coolants release fluorinated gases into the atmosphere.
D
Humans walking to work release nitrous oxide into the atmosphere.
4

Which order of events represents how greenhouse gases trap infrared radiation (IR)?

A
IR absorption, bond movement, more IR absorbed, IR release
B
more IR absorbed, IR release, IR absorption, bond movement
C
IR release, IR absorption, bond movement, more IR absorbed
D
bond movement, more IR absorbed, IR release, IR absorption
6

How do greenhouse gases contribute to the warming of the Earth's atmosphere?

A
Greenhouse gases absorb heat energy.
B
Greenhouse gases absorb air.
C
Greenhouse gases absorb water.
D
Greenhouse gases absorb cold energy.
7

Which best describes how greenhouse gases trap heat?

A
Greenhouse gases absorb the sun's energy directly and prevent it from reaching the Earth's surface, causing the surface to cool down.
B
Greenhouse gases absorb IR radiation emitted by the Earth's surface and re-emit it back towards the Earth, trapping heat.
C
Greenhouse gases combine with IR radiation to form new compounds, removing the heat from the atmosphere.
D
Greenhouse gases reflect the IR radiation into space, reducing the amount of heat trapped in the atmosphere.
8

What does the data show about the rise in carbon dioxide levels compared to temperature change?

A
As the amount of carbon dioxide decreases, temperature change has increased.
B
As the amount of carbon dioxide increases, temperature change has increased.
C
There is no correlation between carbon dioxide amounts and temperature change.
D
As the temperature has decreased, the amount of carbon dioxide has also increased.
9

Which question can be answered correctly about how carbon dioxide affects the Earth’s climate by looking at its shape and how it absorbs energy?

A
Is the ability to absorb infrared energy linked to the double bonds of a molecule?
B
How does a change in carbon dioxide’s shape affect Earth’s climate?
C
Can any three-carbon molecule with triple bonds affect the Earth’s climate?
D
How are the two oxygen atoms and lone carbon atom in carbon dioxide bonded?
10

How does the molecular structure of this fluorinated gas make it highly effective at absorbing energy?

A
The bonds for carbon and hydrogen will absorb heat the energy better.
B
The four fluorine atoms will absorb the most heat energy than any other element.
C
The seven bonds will vibrate more absorbing more heat energy.
D
The more carbon atoms, the more vibration, and the more energy absorbed.
