How does using coal to generate electricity
A. using more coal reduces the amount of pollution from using oil <---------------
B. using improves the quality of nearby water
C. using coal, instead of wood from trees, helps improve the environment
D. using coal releases pollution into the atmosphere
I think the answer is D.
D is correct
its d
The correct answer is D. using coal releases pollution into the atmosphere.
Coal is a fossil fuel that is burned to generate electricity. The process of using coal to generate electricity involves several steps:
1. Mining: Coal is extracted from underground or surface mines.
2. Transportation: The mined coal is transported to power plants or other industrial facilities.
3. Combustion: Coal is burned in a furnace or boiler to produce heat. The heat is used to convert water into steam, which drives a turbine connected to a generator.
4. Generation of electricity: The spinning turbine generates electricity by rotating a magnet inside a coil of wire.
However, the combustion of coal releases several harmful pollutants into the atmosphere, including sulfur dioxide (SO2), nitrogen oxides (NOx), mercury, and particulate matter. These pollutants contribute to air pollution and can have adverse effects on human health and the environment.
It is important to note that using more coal does not reduce pollution from using oil (option A). In fact, coal combustion typically produces more pollution and greenhouse gas emissions compared to oil. Additionally, using coal does not improve the quality of nearby water (option B). Coal mining and power plant operations can contaminate water sources with heavy metals and other pollutants. Lastly, using coal is not considered environmentally beneficial compared to using wood from trees (option C). While burning wood does release carbon dioxide, it is considered more sustainable because trees can be replanted to offset the carbon emissions, whereas coal is a non-renewable resource.
