APES Unit 7 Test Review

Front

What is the pH level of precipitation in the northeastern United States compared to the South Pacific?

Back

Precipitation in the northeastern United States is approximately 10 times more acidic in terms of H+ concentration than that in the South Pacific.

Front

Which type of power plant releases radioactive materials and toxic metals like lead and arsenic?

Back

Coal-burning power plants release radioactive materials and toxic metals such as lead and arsenic under normal operating conditions.

Front

What are the three main anthropogenic sources of gaseous air pollutants in the United States?

Back

The three main anthropogenic sources of gaseous air pollutants in the United States are industry, transportation, and energy production.

Front

Which gas has a stronger affinity for hemoglobin than oxygen?

Back

Carbon monoxide has a stronger affinity for hemoglobin than oxygen.

Front

What is radon?

Back

Radon is a colorless, odorless gas that is a naturally occurring decay product of uranium.

Front

What is the significance of H+ concentration in precipitation?

Back

H+ concentration indicates the acidity of precipitation; higher concentrations mean more acidic rain, which can harm ecosystems.

Front

What are the environmental impacts of coal-burning power plants?

Back

Coal-burning power plants can release toxic metals, radioactive materials, and contribute to air pollution and climate change.

Front

How does carbon monoxide affect human health?

Back

Carbon monoxide can prevent oxygen from binding to hemoglobin, leading to oxygen deprivation in the body.

Front

What role does transportation play in air pollution?

Back

Transportation contributes to air pollution through emissions from vehicles, which release nitrogen oxides, carbon monoxide, and particulate matter.

Front

What is the relationship between energy production and air quality?

Back

Energy production, especially from fossil fuels, is a major source of air pollutants that can degrade air quality and harm public health.
