mobile sources
– such as cars, buses, planes, trucks, and trains. stationary sources – such as power plants, oil refineries, industrial facilities, and factories. area sources – such as agricultural areas, cities, and wood burning fireplaces. natural sources – such as wind-blown dust, wildfires, and volcanoes.
What are 3 main sources of pollution?
The main sources of pollution are
household activities, factories, agriculture and transport
. Once they have been released into the environment, the concentration of some pollutants is reduced by dispersion, dilution, deposition or degradation.
What pollution that comes from many different sources?
Nonpoint source pollution
is difficult to control because it comes from many different sources and locations. Most nonpoint source pollution occurs as a result of runoff. When rain or melted snow moves over and through the ground, the water absorbs and assimilates any pollutants it comes into contact with.
What sources cause the most pollution?
Coal
produces more pollution than any other energy source. While coal produces just 44% of U.S. electricity, it accounts for 80% of power plant carbon emissions. Burning coal leads to soot, smog, acid rain, global warming, and carbon emissions.
What are the 5 sources of pollution?
- Air Pollution. ••• A major source of air pollution results from the burning of fossil fuels. …
- Water Pollution. ••• …
- Soil Pollution. ••• …
- Light Pollution. ••• …
- Noise Pollution. •••
What are the 10 types of pollution?
Major forms of pollution include
air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactive contamination, thermal pollution, visual pollution, and water pollution
.
What are the 10 causes of pollution?
- Combustion from Industry. Almost all of the common air pollutants can be produced by industrial processes. …
- Transportation Emissions. …
- Agriculture Side-Effects. …
- Home Heating. …
- Home Cooking. …
- Volcano Eruptions. …
- Forest Fires. …
- Tobacco Smoke.
What are the natural sources of pollution?
Naturally occurring pollutants include
ash, soot, sulfur dioxide, ground-level ozone (also known as smog)
, salt spray, volcanic and combustion gases, and radon. These pollutants are released during volcanic eruptions, forest fires, and grass fires.
What is one of the biggest sources of air pollution?
The number one source of outdoor air pollution is
the burning of fossil fuels
, primarily by motor vehicles. However, manufacturing industries, mining, and coal- and gas-fired power stations are also responsible for polluting the atmosphere.
Which is most likely a source of air pollution?
In terms of overall range and extents of impacts, however, it is my opinion that
burning of fossil fuels (coal, gasoline, etc..)
is the single largest source of air pollutants. These fuels cause smog, acid rain, soot and particulates increases, greenhouse gas emissions, and dispersal of some heavy metal contaminants.
What contributes most to global warming?
Indeed,
carbon dioxide
, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming. However, other greenhouse gases including methane, nitrous oxide, and a number of industrial-process gases also are important contributors to climate change.
Which fuel source is most likely to decrease air quality?
Nuclear
can go further than any other energy source to reduce air pollution-related health problems and deaths caused by burning fossil fuels.
What is the biggest contributor to global warming?
Electricity and Heat Production
(25% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.
What are the sources of pollution Class 9 it?
Answer: These are
industrial wastes, domestic waste, chemical fertilizers and pesticides
.
What are the main sources of water pollution?
- Industrial waste. Every day, industries produce large amounts of waste. …
- Wastewater and sewage. …
- Marine Dumping. …
- Oil Spills. …
- Pesticides and chemical fertilizers. …
- Sewage and wastewater treatment. …
- Protect large water bodies. …
- Reduction of water as a coolant in power plants and industries.
What are the 7 types of pollution?
When you think of environmental pollution, it typically comes in seven different types. These include
air, water, land, radioactive, thermal, light, and sound pollution.
