Petroleum (crude oil), natural gas, and coal are easy to use for everyday needs that include electricity generation, heating, and transportation. Fossil fuels have become a dominant energy source because they contain a lot of transportable energy in a small package.
Why should we use coal and petroleum judiciously?
Coal and petroleum should be used judiciously because they are limited which wil soon get exhausted or finished and these also pollute our environment. Coal and petroleum were formed millions of years ago from the degradation of biomass. These are exhaustible non-renewable resources.
Is petroleum better than coal?
Coal is cheap and abundant, but it releases a lot of pollutants when burned. Petroleum, or crude oil, is harder to find and is typically a bit cleaner-burning — and, unlike coal, it can be pumped through pipelines and easily refined into fuels like gasoline or kerosene.
What are the uses of coal and petroleum?
These fossil fuels are then refined into usable substances such as petrol, kerosene etc.
Products of Petroleum
- Diesel oil.

Why should we use some resources like coal and petroleum in limit?
Q12: Why should we use some resources like coal and petroleum in limit? Ans: As we know Coal and petroleum are fossil fuels. The dead organisms takes millions of years to get converted into these fuels, On the other hand the known reserves of these will last almost a few hundred years.
How is petroleum obtained?
Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria. … Petroleum reservoirs can be found beneath land or the ocean floor. Their crude oil is extracted with giant drilling machines.
Why the layer containing petroleum and gas is above the water?
Petroleum oil and water are insoluble with each other. Therefore when we mix them both, petroleum oil form layer above water. So, in the deposits, above water there is layer containing petroleum oil and gas. … Petroleum and gas are non polar in nature while water is a polar solvent.
What is the cleanest fuel?
What is the cleanest burning fossil fuel?
What are the disadvantages of using coal and petroleum?
They are non-renewable. They have chemical energy stored within them.
Disadvantages of using fossil fuels
- Fossil fuels are non-renewable energy resources. …
- Coal and oil release sulfur dioxide gas when they burn, which causes breathing problems for living creatures and contributes to acid rain.
Why is coal still used?
That’s largely because of the shale gas revolution, which suddenly made natural gas cheaper than coal for generating electricity. … Global coal use continues to rise, especially in developing economies. About 38 percent of global electricity comes from coal, and in many countries it’s a mainstay for industrial uses, too.
What are the main uses of petroleum?
Petroleum products include transportation fuels, fuel oils for heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials that are in nearly everything we use.
What is difference between coal and petroleum?
Basically, these differences center around the fact that coal is found at its site of deposition as a solid and relatively pure massive organic substance, whereas petroleum is liquid and migrates readily from its place of origin into porous reservoir rocks.
Is coal found in petroleum belt?
