Question

nonpoint source pollution
definition: pollution that comes from, scattered sources across large areas.
characteristics:

• comes from widespread locations
• harder to and control
• often carried by rainfall or snowmelt
• more challenging to regulate

challenge question: why is nonpoint source pollution harder to control than point source pollution?

Explanation:

Non - point source pollution comes from diffuse sources. Since it has widespread locations, it is harder to identify (as opposed to point - source pollution which has a single, identifiable source). And because it is often carried by rainfall or snowmelt, it spreads over large areas, making regulation more difficult.

Answer:

1. diffuse
2. identify

Challenge Question Answer: Nonpoint source pollution is harder to control than point source pollution because it comes from widespread, diffuse sources (not a single, identifiable source like point - source pollution). It is often carried by natural agents like rainfall or snowmelt, spreading over large areas. This makes it difficult to identify the exact sources and implement targeted control measures compared to point - source pollution which has a defined origin.
