Point source pollution means pollution that comes from a single, identifiable source or point. The effects of this type of pollution usually remain relatively local to the point from which the pollution is emanating. Key examples of point source pollution include sewage pipes releasing sewage into a ditch, smokestack style factory chimneys and oil spills.
Nonpoint source pollution means pollution whose source cannot be traced back to a single thing. Nonpoint source pollution is pollution that is more diffuse. It is not concentrated around a particular point or source. This type of pollution and its effects can be seen in the atmosphere, the earth or the sea and other bodies of water. For instance, the high CO2 levels in the atmosphere are caused by many sources, such as factory smoke, people’s cars and so on.
I got this info from ImportantIndia. I hope that this answers your question! Sorry if I am wrong.
I think the one that can impact the climate of an area based on its geographical relief would be : B. Elevation
Mountain exist in a higher elevation lands and ocean exist on the lower elevation. The areas in higher elevation tend to have lower temperature compared to those in lower elevation
