Question: Which of the following best explains why air is considered a natural resource? a. air is expensive to produce and keep clean. b. air is a raw material for biological processes supplied by the earth. c. air can be processed to generate expensive chemicals. d. none of the above?
The correct answer is b. Air is considered a natural resource because it is a raw material for biological processes supplied by the earth. It is a critical resource for life on Earth, providing the oxygen necessary for respiration in plants and animals. While it is true that air can be processed to generate expensive chemicals, this is not the primary reason why it is considered a natural resource. Additionally, while air pollution can be expensive to clean up, this does not mean that air itself is expensive to produce or keep clean.
