state three ways by which (a) air gets polluted (b) water gets polluted (c) soil gets polluted
Answers
Human air pollution is caused by things such as factories, power plants, cars, airplanes, chemicals, fumes from spray cans, and methane gas from landfills. One of the ways that humans cause the most air pollution is by burning fossil fuels. Fossil fuels include coal, oil, and natural gas.
Causes of soil pollution. The most common chemicals involved are petroleum hydrocarbons, solvents, pesticides, lead, and other heavy metals. Any activity that leads to other forms of soil degradation (erosion, compaction, etc.) may indirectly worsen the contamination effects in that soil remediation becomes more tedious.
