What is point source pollution?

Back

Point source pollution refers to contaminants that enter a waterway from a single, identifiable source, such as a pipe or a ditch.

Front

Give an example of point source pollution.

Back

An example of point source pollution is a pipe flowing into a river.

Front

What is a permeable surface?

Back

A permeable surface is one that allows water to pass through it, such as soil or sand.

Front

Which surface is not permeable?

Back

Pavement is not a permeable surface.

Front

What is nutrient pollution?

Back

Nutrient pollution occurs when excess nutrients, like nitrogen and phosphorus, enter water bodies, often from agricultural runoff.

Front

What is a consequence of excessive nutrient pollution?

Back

Oxygen depletion leading to dead zones is a consequence of excessive nutrient pollution.

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.

Front

Define permeability in the context of hydrology.

Back

Permeability is the ability of a material to transmit water through interconnected pores.

Front

What is porosity?

Back

Porosity is the measure of how much empty space (pores) is in a material, which can hold water.
