Coal (fuel source)

Large amounts of coal can be found on the Central Siberian Plateau. The climate there is Tundra and Subarctic, which makes coal very hard to mine, because it's very cold and hard for the ground to stay frozen.

Coal deposits are formed by the remains of plants that were buried and compacted over millions of years. The process involves the accumulation of organic material in swamps and wetlands, which is then subjected to pressure and heat, leading to the formation of coal.

The two methods used for mining coal are surface mining and underground mining. Surface mining involves removing layers of soil and rock to access coal deposits near the surface, while underground mining involves tunneling underground to extract coal from deeper deposits.

Coal can be extracted from the ground through surface mining or underground mining. Surface mining, which includes strip mining and mountaintop removal, involves removing layers of soil and rock to access the coal. Underground mining involves creating tunnels to access coal seams deep within the earth.

Coal is a chemically complex fuel. Whenever it is burned, gases are given off and particles of ash, called "fly ash," are released. The sulfur in coal combines with oxygen to form sulfur dioxide, which can be a major source of air pollution if emitted in large enough quantities.

Today, many of the effects of coal burning have been reduced significantly or eliminated. Three basic methods are used to reduce the quantity of pollutants resulting from coal combustion.

The first, a pre-combustion method for removing contaminates from coal, is coal cleaning or "coal benefication." In coal cleaning the coal is crushed and screened from impurities. Further processing utilizes the different gravities of coal and impurities to separate them in a liquid medium. Coal cleaning can remove the pyritic sulfur, which can reduce sulfur content by as much as 30 percent.

The second, a post-combustion method, uses flue gas desulfurization systems, commonly called scrubbers. According to the Electric Power Research Institute, scrubbers can remove more than 90 percent of the sulfur dioxide emissions from coal combustion. The flue gas is sprayed with a slurry made up of water and an alkaline agent-- usually lime or limestone. The sulfur dioxide reacts chemically, forming calcium sulfate or calcium sulfite. This is removed and disposed of as a wet sludge. There are currently 134 scrubbers operated by the electric utility industry in the United States.

The final method for reducing or eliminating pollution from coal combustion is the use of electrostatic precipitators or baghouses which are used to remove fly ash. In electrostatic precipitators, the particulate matter is given an electrical charge. The charge attracts it to a collector plate, where the particles are collected, preventing their discharge into the atmosphere. In a baghouse, the particulate matter is filtered out as it passes through a series of filters, similar to a household vacuum cleaner.

The two major environmental concerns today dealing with the use of coal are: increase in atmospheric carbon dioxide levels and acid rain. Much remains to be learned about the relationship between fossil fuels (coal, oil, natural gas) and the environment. It is believed that combustion has partially contributed to the increase in atmospheric carbon dioxide levels. Increased atmospheric carbon dioxide levels may result in warmer climates due to the "greenhouse effect." The increase in atmospheric carbon dioxide prevents heat from escaping from the earth, thus warming the atmosphere.

The combustion of coal also appears to contribute to acid rain, although precise measures of the scope and seriousness of acid rain are not clear or well understood. What is clear is that further study of the phenomenon is necessary.

There is an interesting riddle to the acid rain phenomenon, and that is that acid rain damage has occurred during periods when sulfur dioxide discharges have declined or remained stable (sulfur dioxide is considered to be the principal cause of acid rain).

Burning coal releases greenhouse gases such as carbon dioxide, contributing to climate change. It also releases sulfur dioxide and nitrogen oxides, which can lead to acid rain and air pollution. Coal mining can cause habitat destruction, water pollution, and harm to wildlife.

Coal deposits formed from the remains of ancient plants and trees that were buried and compacted over millions of years. The decaying plant material was subjected to high pressure and heat, which transformed it into coal. The process is known as coalification.

The burning of fossil fuels releases carbon dioxide into the atmosphere, contributing to the greenhouse effect and global warming. This can lead to an increase in evaporation rates and changes in precipitation patterns, impacting the water cycle by altering the amount and distribution of rainfall.

Coal is actually one of the most abundant fossil fuels on Earth. It is estimated that there are large reserves of coal in many countries around the world. Oil and natural gas are generally considered to be less common than coal.

The largest reserves of coal are found in the United States, Russia, Australia, China, and India. These countries account for the majority of the world's coal reserves.

Coal is a non-renewable fossil fuel that emits greenhouse gases when burned, contributing to climate change and air pollution. Using coal negatively impacts the environment by releasing carbon dioxide and other pollutants into the atmosphere. There are cleaner and more sustainable energy sources available, such as renewable energy sources like solar and wind power, that can help protect the environment.

The removal of coal through mining can cause environmental damage such as deforestation, soil erosion, and water pollution. It can also contribute to air and water pollution through the release of harmful chemicals and greenhouse gases during the mining and burning process, leading to an overall negative impact on local ecosystems and human health.

Potash is not typically used as an energy source. It is primarily used in fertilizer production due to its high potassium content, rather than for energy generation. Uranium, coal, and petroleum are used as energy sources in the southwest and around the world.

Lava forms underground in magma chambers. When it erupts onto the Earth's surface through volcanic activity, it becomes lava.

You may put some burning fuel (as a piece of coal or some gasoline, etc..) under an airtight pot connected to vacuum system to suck air. You notice on sucking the air the diminishing of the burning until got completely off. Even if you don't such the air, the burning will get less and less due to the consumption of the limited Oxygen inside the pot.

A miner is a person who digs coal, bauxite, or diamonds from the earth. Miners work in mines to extract these precious resources, which are used in various industries like energy, manufacturing, and jewelry.

Coal is extracted where it is found in deposits beneath the Earth's surface. Factors such as geological conditions, energy demand, and economic feasibility influence the location of coal extraction. Additionally, infrastructure such as transportation networks may also play a role in determining where coal is mined.

Estimates vary, but it is generally predicted that the world's coal reserves could last for around 100 to 200 years at current consumption rates. However, factors such as changes in technology, energy policies, and environmental concerns could impact the actual duration of coal reserves.

According to the US Institute for Energy Research, coal in 2005 was responsible for 26% of global energy production. This percentage is dropping each year as more countries and power plants move to oil and gas, the burning of which releases less harmful carbon dioxide emissions than coal. There is movement too in the establishment of renewable energy power (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel).

Coal mines can be found in several countries around the world, including China, the United States, India, Australia, and Indonesia. These countries have significant coal reserves and active mining operations.

Coal and limestone are sometimes referred to as biological rocks because they are formed from the remains of once-living organisms. Coal is derived from ancient plant material that has undergone a process of burial and transformation, while limestone is composed of the skeletal remains and shells of marine organisms like corals and mollusks. This biological origin is reflected in the organic nature of these rocks.

• It makes people switch to new fuel sources.

• It leaves less pollution in the ground.

• It makes less air pollution in Poland.

• It cleans the coal so there is no waste.

A person who gets coal from under the ground is typically called a coal miner.

All hydrocarbon based fuels add to the "green house effect" by emitting CO2, carbon dioxide. This carbon dioxide causes the Earth's atmosphere to refract sunlight in such a way that it actually warms the planet a little more.

Burning fossil fuels releases greenhouse gases like carbon dioxide into the atmosphere, contributing to global warming and climate change. This leads to an increase in the Earth's temperature, changes in weather patterns, and negative impacts on ecosystems and biodiversity. Additionally, it can result in air pollution, posing health risks to humans and wildlife.
