What is thermal pollution?

Back

Thermal pollution is the increase in temperature of natural water bodies caused by human activities, such as industrial discharges, which can harm aquatic life.

Front

What type of pollution results from excess fertilizer runoff after rain?

Back

Nutrient pollution occurs when excess fertilizers wash into water bodies, leading to algal blooms and oxygen depletion.

Front

What type of pollution is caused by the careless disposal of living microbes down the drain?

Back

Bacterial pollution occurs when harmful bacteria enter water bodies, often from improper disposal of biological materials.

Front

What is non-point source pollution?

Back

Non-point source pollution refers to contaminants that come from multiple diffuse sources, such as runoff from agricultural fields, rather than a single identifiable source.

Front

Define water pollution.

Back

Water pollution is the introduction of harmful chemical, physical, or biological agents into water bodies, degrading water quality and affecting ecosystems.

Front

What is chemical pollution?

Back

Chemical pollution involves the contamination of water bodies with harmful chemicals, such as pesticides, heavy metals, and industrial waste.

Front

What is sediment pollution?

Back

Sediment pollution occurs when excessive soil, sand, or silt enters water bodies, often due to erosion, which can harm aquatic habitats.

Front

What is the impact of nutrient pollution on aquatic ecosystems?

Back

Nutrient pollution can lead to algal blooms, which deplete oxygen in the water, harming fish and other aquatic organisms.

Front

What are point source pollutants?

Back

Point source pollutants are contaminants that originate from a single, identifiable source, such as a pipe or a factory discharge.

Front

What is the role of a watershed in water quality?

Back

A watershed is an area of land that drains into a particular water body; it plays a crucial role in collecting and filtering water before it enters rivers and lakes.
