How does burning fossil fuels affect the nitrogen cycle?
Burning fossil fuels alters the amount of nitrogen in the Earth's atmosphere. Specifically, there has been a significant increase in nitric oxide levels since the beginning of the Industrial Revolution.
Why has the twentieth century been called the hydrocarbon century?
It was called the hydrocarbon century due to abundant usage of fossil fuels.
How is fossil fuels man made?
A fossil is a relic of earlier times, that is found in the ground. By definition, it is not man made. People can make fuel, for example, we can grow corn, and then extract corn syrup, ferment it to make alcohol, and burn the alcohol. But that is not a fossil fuel. Petroleum, natural gas, and coal are the fossil fuels. We did not make them, they have been in the ground for a long time before we came along.
How long will it take for all of the petroleum based fuels to be depleted?
Unknown, because they are constantly finding new fossil fuels and new ways to get at the fuels. Additionally, new technologies have been developed that can extract more fuel from previously depleted fossil fuel fields. An example is the 2 newly discovered oil fields in the continental United States that are huge.
Is hydrogen renewable?
Hydrogen is renewable in the sense that the fossil fuels we use are hydrocarbon compounds. When we burn them, the hydrogen is liberated in the form of water vapors or hydrogen compounds. These vapors then mix with various gases in the atmosphere to form other compounds like nitric acid, etc. It then comes down with the rain and is deposited on the earth. It thus stays in the system only. Unlike fossil fuels, the hydrogen can be extracted whenever required (fossil fuels need millions of years to produce). Hence hydrogen is considered renewable. At the same time, the energy required to separate hydrogen from the compounds it is a part of often comes from nonrenewable sources, including fossil fuels. Hydrogen does not exist in its elemental state naturally, it is almost always found in compounds like water, so the compound must be broken up by electrolysis or some other means, which requires energy. Research into solar powered electrolysis and hydroelectric powered electrolysis has been done, but it's not yet viable on a large scale. Hydrogen has been produced on a large scale by steam methane reforming. This is not renewable because it involves using methane (a fossil fuel) and getting it to incredibly high temperatures by using more fossil fuels. In some cases around 70% of the gasses produced were not hydrogen but carbon based compounds.
Are there fossil fuels on Mars?
No one could possibley know that. Humans haven't been there. -Jonhis
What is in fossil fuels?
In a fossil fuel is different fuels that have been burned
Why have fossil fuels become your primary energy resource?
Fossil fuels have become a primary energy resource because it is easy to use, not as expensive, and easily found normally. Also people have been so accustomed to using fossil fuels.
How can the society change the continuous use of fossil fuels?
We need to burn fossil fuels now to produce electricity and power our transport. When we do this we release carbon that has been buried for millions of years. Before we can stop burning fossil fuels we need to develop other ways of generating electricity, like better ways of using solar, wind, water and thermal energy. When we can do this efficiently then we can stop using fossil fuels.
How can humans worsen the effects of burning fossil fuels?
Humans can worsen the effects of burning fossil fuels (coal, oil and natural gas) by cutting down the great forests of the world. This, sadly, has already been done, so the forests no longer remove carbon dioxide from the atmosphere.
What cycle do humans affect by burning fossil fuels?
We affect the earth's regular carbon cycle by burning fossil fuels. Coal and oil combustion adds billions of tons of carbon to the atmosphere, carbon that has been stored underground for millions of years.
Why are these resources referred to as fossil fuels?
"Fossil fuels" refers to fuels, such as carbon and petroleum, that are generally believed to originate as fossils.
Fuels that can only be used once?
It can never be true that fossil fuels can be used only once because fossil fuels can be made again but if it has been buried it will take a longer time
How do nonrenewable fuels run out?
An example of non-renewable resources is fossil fuels. Once fossil fuels have been used up and no new sources found, then we can no longer use fossil fuels. A source of energy will no longer be available to us. It took many million of years for nature to produce fossil fuels, something we are unable to repeat.
What do you think about the resources humans use?
Fossil fuels (coal, oil and natural gas). We thought it was an amazing resource, and it is, but we didn't realise, when we started burning it, that it was releasing carbon dioxide that had been hidden away for 300 million years. Now the world is hurriedly trying to produce enough renewable, non-polluting energy so we can stop using fossil fuels permanently.
Why is solar power not used as much as fossil fuels?
They have been the most efficient energy source available
When were fossil fuels invented?
Fossil fuels were never invented, they were discovered. Some people think that coal may have been used as fuel in prehistoric times.
