What is point and nonpoint source?

Point and Nonpoint Pollution Sources Pollution originating from a single, identifiable source, such as a discharge pipe from a factory or sewage plant, is called point-source pollution. Pollution that does not originate from a single source, or point, is called nonpoint-source pollution.

What is an example of a point source?

Examples include smokestacks, discharge pipes, and drainage ditches. Factories and power plants can be a source of point-source pollution, affecting both air and water. Smokestacks may spew carbon monoxide, heavy metal, sulfur dioxide, nitrogen dioxide, or “particulate matter” (small particles) into the air.

What is the difference between nonpoint and point source pollution?

The main difference between point source and nonpoint source pollution is that the point source pollution occurs through a specific, identifiable source whereas the nonpoint source pollution occurs through a combination of pollutants from a large area.

What is a point source of energy?

A point source is an area or physical place or thing from which something is produced or released. In physics it can be defined as a source of energy including sound or light energy.

What is point source and non point source of water pollution?

A point source is a pipe or channel, such as those used for discharge from an industrial facility or a city sewerage system. A dispersed (or nonpoint) source is a very broad unconfined area from which a variety of pollutants enter the water body, such as the runoff from an agricultural area.

What is the difference between point source and nonpoint-source pollution quizlet?

Point source pollution has a known and specific location. Nonpoint source pollution does not have a specific point of origin.

Which of the following is a point source?

Examples of point sources include sewage treatment plants; oil refineries; paper and pulp mills; chemical, automobile, and electronics manufacturers; and factories. Regulated pollutants from point sources include wastes, soils, rocks, chemicals, bacteria, suspended solids, heavy metals, pesticides, and more.

What is the difference between a point source and a nonpoint source quizlet?

What is the difference between a point source and a non-point source provide a few examples of each which is easier to control?

A point source is a type of pollution that can be seen and a non-point source is a source that is not easy to link to anything specific. An example of a non-point source is animal waste and an example of a point source is seeing a pipe from a building running directly to a stream.

What is an extended source?

1 A source of angular size greater than the resolution of the instrument used to observe it; therefore, an extended source is said to be resolved. To the human eye, the Sun and Moon are extended sources, but the stars and planets are not. See also Point Source.
