Detailed explanation-1: -A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects the ecosystem.

Detailed explanation-2: -The main emissions from coal combustion at thermal power plants are carbon dioxide (CO2), nitrogen oxides, sulfur oxides, chlorofluorocarbons (CFCs), and airborne inorganic particles such as fly ash and soot; CO2, methane, and CFCs are greenhouse gases.

Detailed explanation-3: -Which of the following is the main reason for thermal pollution? Explanation: Power plants are the main reasons behind growing thermal pollution.

Detailed explanation-4: -All these thermal power plant has produces by-product after burning coal as an energy inputs. The by-product obtained in the form of fine ash which has been known as fly ash and bottom ash. These by-products directly dump on the nearby area or thrown into low lying areas.
