  3. Soil degradation

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil contamination, soil pollution, and soil degradation all refer to the process by which soil becomes contaminated with pollutants. Soil contamination can occur through a variety of sources, including industrial activities, agricultural practices, and improper waste disposal.

Multiple choice

What is the term for the process by which pollutants are transported through the environment?

  1. Environmental transport

  2. Environmental fate

  3. Environmental distribution

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Environmental transport, environmental fate, and environmental distribution all refer to the process by which pollutants are transported through the environment. Pollutants can be transported through the air, water, or soil. The fate of a pollutant depends on its chemical properties, the environmental conditions, and the presence of other pollutants.
