  1. Deforestation

  2. Industrial waste

  3. Agricultural chemicals

  4. Ocean currents
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Agricultural chemicals, such as fertilizers and pesticides, are a major source of soil pollution. These chemicals can contaminate soil and groundwater, harming soil organisms, reducing soil fertility, and posing risks to human health.

Multiple choice

What is the main source of water pollution in the United States?

  1. Industrial wastewater

  2. Municipal wastewater

  3. Agricultural runoff

  4. Stormwater runoff
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Agricultural runoff is the leading source of water pollution in the United States. It contains fertilizers, pesticides, and animal waste, which can contaminate surface water and groundwater. Industrial wastewater and municipal wastewater are also significant sources of pollution, but they are typically treated before being discharged into the environment.
