Question 1

Match the term with the appropriate description. Terms may be used once or more than once.
-gases released when bacteria feed on fertilizers and animal waste

Accepted Answer

Gases released when bacteria feed on fertilizers and animal waste are nitrogen oxides.

Question 2

Global climate change is caused by ____ and other greenhouse gases.

Accepted Answer

Carbon dioxide is one of the primary greenhouse gases responsible for global climate change. While other gases like ozone and methane can also contribute to the problem, carbon dioxide is the most significant and well-known. Nitrogen, oxygen, and argon are present in the atmosphere but do not have a significant effect on the Earth's climate.

Question 3

Individuals and conservation groups have donated funds to buy land in the Monteverde Cloud Forest in Costa Rica. As a result, much of the forest is now protected as a private nature reserve. This is an example of ____.

Accepted Answer

Preservation refers to the protection of natural resources and ecosystems from being exploited or destroyed. In this case, individuals and conservation groups have donated funds to protect land in the Monteverde Cloud Forest, which means that the forest is being preserved and protected as a private nature reserve.

Question 6

One of the symptoms of global warming is a decrease in the persistence of sea ice in the Arctic, which affects polar bears by ____.

Accepted Answer

Polar bears rely heavily on sea ice as a platform for hunting seals. A decrease in the persistence of sea ice reduces their access to seals and can negatively impact their survival.

Question 7

Match the term with the appropriate description. Terms may be used once or more than once.
-odorless gases used as propellants in aerosol cans, as coolants, and in solvents and plastic foam

Accepted Answer

CFCs (chlorofluorocarbons) are odorless gases that have been widely used as propellants in aerosol cans, as coolants, and in solvents and plastic foam.

Question 8

What role does wind play in desertification?

Accepted Answer

Wind is a major contributor to desertification because it blows away topsoil, leaving the land unable to support vegetation. This process can also create dust storms that further damage the land and make it difficult for plants to grow.

Question 9

A species that is confined to the limited area in which it evolved is ____.

Accepted Answer

Endemic species are those that are found only in a specific geographic area, such as an island, a mountain range, or a specific ecosystem. They are often in danger of extinction if their habitat is destroyed or altered. Endangered species are those that are at risk of becoming extinct, threatened species are those that are likely to become endangered in the near future, extinct species no longer exist, and exotic species are non-native to a specific ecosystem or geographical area.

Question 10

Match the term with the appropriate description. Terms may be used once or more than once.
-produced when airborne pollutants coat dust particles that fall to the ground

Accepted Answer

Dry deposition is the process by which pollutants settle onto surfaces without the aid of precipitation. This can occur when airborne pollutants (such as sulfur dioxides, nitrogen oxides, and CFCs) coat dust particles that fall to the ground.

Answer: A, B, E 
 Sulfur dioxides, nitrogen oxides, and CFCs are all types of airborne pollutants that can contribute to air pollution.

Question 11

Match the term with the appropriate description. Terms may be used once or more than once.
-air pollutants released by coal-burning power plants

Accepted Answer

The answer of Match the term with the appropriate description....

Question 12

Match the term with the appropriate description. Terms may be used once or more than once.
-irritates the eyes and respiratory tracts of animals when it forms in the lower atmosphere

Accepted Answer

Ozone, when present in the lower atmosphere (troposphere), acts as an irritant to the eyes and respiratory tracts of animals.

Question 13

Match the term with the appropriate description. Terms may be used once or more than once.
-main ozone destroyers prior to the Montreal Protocol

Accepted Answer

CFCs were the main ozone destroyers prior to the Montreal Protocol.

Question 14

Match the term with the appropriate description. Terms may be used once or more than once.
-benefits life when it is in the upper layer of the atmosphere by absorbing UV radiation from incoming sunlight

Accepted Answer

Ozone benefits life when it is in the upper layer of the atmosphere by absorbing UV radiation from incoming sunlight.

Question 15

Match the term with the appropriate description. Terms may be used once or more than once.
-​currently the main ozone destroyers

Accepted Answer

The answer of Match the term with the appropriate description....

Question 16

What benefits living organisms by absorbing most ultraviolet (UV) radiation from incoming sunlight?

Accepted Answer

The ozone layer absorbs most of the harmful UV radiation from the sun, protecting living organisms on Earth from the damaging effects of UV radiation. Nitrogen, carbon dioxide, chlorofluorocarbons, and sulfur oxides do not provide this benefit.

Question 17

California's native golden trout declined after European brown trout and eastern brook trout were introduced into California's mountain streams for sport fishing. This is an example of what type of threat?

Accepted Answer

The introduced brown trout and eastern brook trout are considered invasive species and posed a threat to the native golden trout population.

Question 18

There is an ozone "hole" over ____.

Accepted Answer

The ozone hole is predominantly located over Antarctica.

Question 19

What is ecological restoration?

Accepted Answer

The answer of What is ecological restoration?...

Question 20

A species that faces extinction in all or part of its range is ____.

Accepted Answer

The term "endangered" is used for a species that is at risk of extinction in all or part of its range.
