Question

what are definite and non definite sources of pollution​

Answer 1

Explanation:

Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. ...

As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground water

Answer 2

Answer:

Definite  sources of pollution​ :The main sources of pollution are household activities, factories, agriculture and transport. Once they have been released into the environment, the concentration of some pollutants is reduced by dispersion, dilution, deposition or degradation.

Non definite sources of pollution​ : Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. Oil, grease and toxic chemicals from urban runoff and energy production. Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks.
