Human Impact and River Health

Front

What is the main cause of algae blooms in water systems?

Back

Large amounts of nitrates in runoff.

Front

What is a non-point source of pollution?

Back

Pollution that comes from multiple sources, such as fertilizer runoff from lawns.

Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles.

Front

What is runoff?

Back

Runoff is water that flows over the ground surface and can carry pollutants into water bodies.

Front

How do fertilizers affect pond ecosystems?

Back

Fertilizers can lead to nutrient overload, causing algae blooms that deplete oxygen and harm aquatic life.

Front

What is the impact of sediment in water?

Back

Sediment can increase turbidity, block sunlight, and harm aquatic plants and animals.

Front

What role does rain play in water pollution?

Back

Rain can wash pollutants like pesticides and fertilizers into streams and lakes.

Front

What is the difference between point source and non-point source pollution?

Back

Point source pollution comes from a single, identifiable source, while non-point source pollution comes from multiple, diffuse sources.

Front

What are the effects of high turbidity on aquatic life?

Back

High turbidity can reduce light penetration, affecting photosynthesis and harming aquatic organisms.
