APES Semester 1 Review

Front

What happens to the lion population if the zebra population drops?

Back

The lion population will likely drop due to a decrease in available prey.

Front

What is one cause of Global Warming?

Back

Burning fossil fuels and pollution from factories are both causes of Global Warming.

Front

What percentage of the atmosphere is made up of nitrogen?

Back

Nitrogen makes up 78% of the atmosphere.

Front

What are the reactants needed to form tropospheric ozone?

Back

NO2, VOCs, O2, and sunlight are needed to form tropospheric ozone.

Front

What are secondary air pollutants?

Back

Secondary air pollutants are produced by interactions between primary air pollutants or between primary air pollutants and other atmospheric gases.

Front

Define primary air pollutants.

Back

Primary air pollutants are substances directly emitted from a source, such as tailpipes and smokestacks.

Front

What is the role of VOCs in air pollution?

Back

VOCs (Volatile Organic Compounds) contribute to the formation of secondary pollutants like tropospheric ozone.

Front

Explain the greenhouse effect.

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What is the significance of the Clean Air Act?

Back

The Clean Air Act regulates air emissions from stationary and mobile sources to protect public health and the environment.

Front

What is the difference between point and non-point sources of pollution?

Back

Point sources are identifiable and localized (e.g., factories), while non-point sources are diffuse and harder to regulate (e.g., agricultural runoff).
