D) The average temperatures decreased in comparison to the temperatures between 1920 and 1950.

Question 5

In 2018, a majority of carbon dioxide that entered the atmosphere in the United States came from energy burned:

A) to power transportation.
B) to power residential and commercial uses.
C) to power industry.
D) from agriculture fertilizer or the production of feed animals.

Question 6

Which of the following is true of carbon sinks?

A) Carbon sinks are being created by the destruction of rain forests.
B) The creation of more carbon sinks contributes to rising temperatures.
C) As the amount of CO₂ in the atmosphere rises, more is absorbed by natural systems.
D) Carbon sinks have the capacity to isolate some of the atmospheric carbon.

Question 7

Which of the following is an example of subsidence?

A) Expansion of oceans as a result of excess heat
B) The sinking of land in some coastal areas
C) The melting of the ice sheet in the Arctic over the North Pole
D) Increasing sea levels as a result of higher tides

Question 8

For every degree of higher temperature, the air can hold __________ more moisture.

A) 1-2%
B) 2-4%
C) 4-7%
D) 7-10%

Question 9

What cautionary statement is associated with an air quality of 201 to 300 ppb?

A) No health impacts are expected.
B) Unusually sensitive people should limit prolonged outdoor exertion.
C) Active children and adults should limit prolonged outdoor exertion.
D) Active children and adults should limit any outdoor exertion.

Question 10

________________ is the degree to which people or communities are affected, either adversely or beneficially, by a varying climate or other change.

A) Exposure
B) Sensitivity
C) Adaptive capacity
D) Vulnerability

Question 11

Air is less dense and colder in the troposphere than in the stratosphere.

Question 12

Much of the carbon 14 in the carbon dioxide in the Earth's atmosphere has not degraded much so we can conclude that it was placed there recently.

Question 13

The overall quantity of methane emissions is less than CO₂ emissions, but has a greater effect than CO₂.

Question 14

Nearly all of the greenhouse gases that have accumulated in the atmosphere are from fossil fuels.

Question 15

Global warming is shortening the growing season, decreasing the length of pollen seasons.
