What Causes Minimum Pollution?

What causes the least pollution?


Natural gas is the cleanest fuel and causes the least pollution when burnt compared to petrol, diesel and coal..

Which of the following is a pollution fuel?

Globally, the majority of air pollution is generated by the combustion of fossil fuel (coal, diesel fuel, gasoline, oil, and natural gas) for electricity production, heating, transportation, and industry [14].

Which mode of transport causes the most pollution?

Still, planes remain among the most polluting means of transport, together with cars. On a journey of, for example, 500 hundred kilometers, a plane pollutes 10 to 50 times more than a high-speed electric train and 5 to 10 times more than a bus.

Which is the fastest mode of transport?

Air transportAir transport is the fastest method of transport, Commercial jets reach speeds of up to 955 kilometres per hour (593 mph) and a considerably higher ground speed if there is a jet stream tailwind, while piston-powered general aviation aircraft may reach up to 555 kilometres per hour (345 mph) or more.

Which fossil fuel produces the least air pollution?

In terms of emissions from power plant sources, natural gas is the cleanest fossil fuel. Using data collected from the Energy Information Administration (EIA) division of the Department of Energy (DOE), the emissions of several stack gasses are compared for natural gas, oil, and coal.

Which fuel causes the maximum pollution?

carbon monoxideAnswer. carbon monoxide is the gas which causes maximum amount of air pollution.

Which mode of transport does not cause pollution?

Cycle is the vehicle which does not pollute the environment. Cycles do not need fossil fuels, so that they do not emit any harmful gases. So, cycle is an eco-friendly mode of transport. Cycling 10 km each way to work would save 1500 kg of greenhouse gas emissions each year.

What are the 3 main causes of air pollution?

Various Causes of Air pollutionThe Burning of Fossil Fuels. … Agricultural Activities. … Waste in Landfills. … Exhaust From Factories and Industries. … Mining Operations. … Indoor Air Pollution. … Natural Events.

How do fossil fuels harm the environment?

Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change. In the United States, the burning of fossil fuels, particularly for the power and transportation sectors, accounts for about three-quarters of our carbon emissions.

What are 10 ways to reduce pollution?

10 Best Ways to Reduce Air PollutionUsing public transports. … Turn off the lights when not in use. … Recycle and Reuse. … No to plastic bags. … Reduction of forest fires and smoking. … Use of fans instead of Air Conditioner. … Use filters for chimneys. … Avoid usage of crackers.More items…•Sep 8, 2017

Why do we need to save fuel?

Save Fuel for a Better Environment However, there is a more important reason to conserve fossil fuels, and that’s to help heal the environment. Burning petroleum, coal and natural gas fills the air with harmful pollutants, including nitrogen oxides, sulfur dioxide, carbon dioxide, ozone and a host of hydrocarbons.

What is the role of fossil fuel in air pollution?

Cars and trucks release nitrogen into the atmosphere, which contributes to nutrient pollution in our air and water. When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain. …

How bad are fossil fuels for the environment?

Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide (SO2) emissions, primarily the result of burning coal, contribute to acid rain and the formation of harmful particulate matter.

What is pollution very short answer?

Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.

What causes this pollution?

The Short Answer: Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.

Which fuel is caused least pollution?

Hydrogen-fueled vehicles emit virtually no hydrocarbons, particulates, carbon dioxide, or carbon monoxide. They are viewed as an especially attractive option for reducing green house gas emissions.

How do fossil fuels cause air pollution Class 9?

When fossil fuels are burnt it produces oxides of nitrogen and sulphur. These gases cause inhalation problems and in presence of rain forms acid rain. Burning of fossil fuels also increase the amount of suspended particles in air that reduce the visibility.

Which is the most eco friendly mode of transport?

Public transport overall is generally considered to be one of the better options when it comes to reducing the negative environmental impact of urban mobility. Taking a bus, even if it runs on diesel, as the majority do, is exponentially better than taking an electric car or taxi.

Which fuel is less polluting and why?

Answer: the fuels like CNG, LPG, biofuels are the fuels which are less polluting. Explanation: these fuels are less polluting because carbon content is lesser due to which the threat of increase of carbon in the is reduced and the stress of increase of global warming is also reduced.
