Question

point source pollution is-

multiple small sources of pollution which can add up to one large source in a broad area.
most often related to runoff from urbanized areas near an ocean.
a general area in which pollution can be discharged.
any single identifiable source of pollution which pollutants are discharged.

Explanation:

Define point source pollution

Using the Point Source Pollution knowledge point
Point source pollution refers to any single, identifiable source from which pollutants are discharged, such as a pipe, ditch, ship, or factory smokestack.

Evaluate the given options

• Option 1 describes nonpoint source pollution, where multiple small, diffuse sources accumulate over a broad area.
• Option 2 describes urban runoff, which is typically a form of nonpoint source pollution.
• Option 3 is too vague and does not specify a single, distinct point of origin.
• Option 4 directly matches the standard scientific definition of point source pollution.

Answer:

• multiple small sources of pollution which can add up to one large source in a broad area.
• most often related to runoff from urbanized areas near an ocean.
• a general area in which pollution can be discharged.
• any single identifiable source of pollution which pollutants are discharged. (Correct answer)
