Question 1

Which of the following impacts on human health are caused by climate change's effect on water quality?

Accepted Answer

Climate change affects water quality, leading to the spread of waterborne diseases like cholera and campylobacter.

Question 2

A majority of the atmosphere that surrounds earth is composed of:

Accepted Answer

The Earth's atmosphere is composed of approximately 78% nitrogen, making it the most abundant gas.

Question 3

Which of the following is true of how the Sun's rays interact with the Earth?

Accepted Answer

Some of the infrared energy emitted by the Earth's surface is absorbed by greenhouse gases, but not all; some of it escapes into space.

Question 4

Which of the following was true about the average temperatures between 1950 and 1980?

Accepted Answer

The answer of Which of the following was true about...

Question 5

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

Accepted Answer

In 2018, the largest source of carbon dioxide emissions in the United States was from the transportation sector, which includes cars, trucks, ships, trains, and planes.

Question 6

Which of the following is true of carbon sinks?

Accepted Answer

The answer of Which of the following is true of...

Question 7

Which of the following is an example of subsidence?

Accepted Answer

Subsidence refers to the gradual sinking or settling of the Earth's surface, which is exemplified by the sinking of land in some coastal areas.

Question 8

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

Accepted Answer

For every degree Celsius increase in temperature, the air can hold approximately 4-7% more moisture.

Question 9

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

Accepted Answer

The answer of What cautionary statement is associated with an...

Question 10

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

Accepted Answer

The answer of ________________ is the degree to which people...

Question 11

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

Accepted Answer

The troposphere is denser and generally colder than the stratosphere, but temperature increases with altitude in the stratosphere due to the absorption of ultraviolet radiation by the ozone layer.

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.

Accepted Answer

Carbon-14 is a radioactive isotope with a half-life of about 5,730 years. If much of the carbon-14 in atmospheric carbon dioxide has not degraded, it suggests that it was introduced relatively recently, as it has not had sufficient time to decay significantly.

Question 13

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

Accepted Answer

Methane is more effective at trapping heat in the atmosphere than CO2, making it a more potent greenhouse gas despite being emitted in smaller quantities.

Question 14

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

Accepted Answer

Fossil fuels are the primary source of greenhouse gas emissions, accounting for approximately 80% of the total emissions.

Question 15

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

Accepted Answer

Global warming is generally lengthening the growing season and increasing the length of pollen seasons due to warmer temperatures and earlier springs.
