Unit 1: Energy Conservation & Transfer Formative

The difference between a point source and a nonpoint source of water pollution is:

• a nonpoint source is easily identifiable

• point sources can be targeted for reduction

• point sources tend to be agricultural in nature

• nonpoint sources are less harmful to the environment

• 
  it can increase the number of invasive species in an area

• It can decrease the risk of water pollution in an area

• It can increase the risk of flooding in an area

•
