To categorize the images based on point source pollution and nonpoint source pollution:
-
Point source pollution: This type of pollution can be traced back to a single, identifiable source. In this case, the black liquid dumping into a body of water from a pipe is an example of point source pollution because it comes from a specific location.
-
Nonpoint source pollution: This type of pollution comes from multiple sources that are not easily identifiable. The polluted beach, the oil floating in the water (which is caused by the oil rig), and trash littering the side of a roadway are all examples of nonpoint source pollution, as these pollutants come from various diffuse sources rather than a single point.
Based on this classification, here's how to drag them:
- Point source pollution: Black liquid dumps into a body of water from a pipe.
- Nonpoint source pollution: A polluted beach is shown, Oil floats in the water underneath an oil rig that sits on the surface of a body of water, Trash litters the side of a roadway.
