Unit 5 Air & Water Pollution Test Review

Front

What is nutrient pollution?

Back

Nutrient pollution occurs when excess nutrients, primarily nitrogen and phosphorus, enter water bodies, leading to algal blooms and oxygen depletion.

Front

What is a greenhouse gas?

Back

A greenhouse gas is a gas that traps heat in the atmosphere, contributing to the greenhouse effect. Common examples include carbon dioxide, methane, and water vapor.

Front

What is the most significant greenhouse gas produced by human activity?

Back

Carbon dioxide is the most significant greenhouse gas produced by human activity, primarily from burning fossil fuels.

Front

What is point source pollution?

Back

Point source pollution refers to contaminants that enter a water body from a single, identifiable source, such as a pipe or a drain.

Front

What is nonpoint source pollution?

Back

Nonpoint source pollution comes from multiple, diffuse sources, making it difficult to identify and control, such as runoff from agricultural fields.

Front

What are the main sources of air pollution?

Back

The main sources of air pollution include vehicle emissions, industrial discharges, and burning fossil fuels.

Front

What is the impact of fertilizer runoff on water bodies?

Back

Fertilizer runoff can lead to nutrient pollution, causing algal blooms that deplete oxygen in the water, harming aquatic life.

Front

What is the role of sulfur dioxide in air pollution?

Back

Sulfur dioxide is a significant air pollutant that can cause acid rain and respiratory problems in humans.

Front

What is 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 thermal inversion?

Back

Thermal inversion is a weather phenomenon where a layer of warm air traps pollutants close to the ground, leading to increased air pollution.
