How are coal and petroleum found describe the distribution of major oil and coal fields in the world?

How is coal and petroleum found?

Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.

Why is petroleum unevenly distributed throughout the world?

It is because of the earths formation that we find unequal distributions. Latitudes close to the equator receive more energy from the sun and more precipitation. Latitudes that are closer to the poles, are the opposite, they receive few of the sun’s energy and very little precipitation.

What are 4 types of coal?

Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.

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.

What do coal and oil have in common?

Both coal and oil are fossil fuels. That means they’re formed from organic matter – stuff that was alive on Earth millions of years ago – that was covered by heavy layers of rock. Both coal and oil are carbon-based fuels – they’re made up mostly of carbon and hydrogen.

Which is the cleanest fuel?

Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted — making natural gas the cleanest burning fossil fuel of all.

What three countries are the highest oil consumers?

Oil Consumption by Country

# Country Daily Oil Consumption (barrels)
1 United States 19,687,287
2 China 12,791,553
3 India 4,443,000
4 Japan 4,012,877

Which fossil fuel is the most evenly distributed globally?

It is highly compressed in small volumes at large depths in the earth. Like oil, it is brought to the surface by drilling. Natural gas reserves are more evenly distributed around the globe than oil supplies. Energy gained from burning fossil fuels is converted to electricity and heat in commercial power plants.
