Coal (fuel source)

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.

Burning fossil fuels like coal emits greenhouse gases such as carbon dioxide, contributing to climate change and global warming. It also releases pollutants like sulfur dioxide and nitrogen oxides, leading to air pollution, acid rain, and health problems for humans and wildlife. The extraction and transportation of coal can also result in habitat destruction and water pollution.

Coal formed in ancient swamp environments, where plant material accumulated in oxygen-poor conditions, allowing for its preservation and transformation into coal over millions of years.

Yes, there are coal deposits in Antarctica, particularly in the Transantarctic Mountains. However, mining activities are prohibited under the Protocol on Environmental Protection to the Antarctic Treaty due to environmental concerns.

Miners typically dig underground for coal. They work in coal mines to extract coal from the earth, which is then used for various purposes such as energy production and manufacturing. Mining for coal can be a hazardous job due to potential risks such as cave-ins, gas explosions, and long-term health issues related to exposure to coal dust.

Coal is generally considered a sedimentary rock as it is made up of deposited material (in this case organic matter, mostly from plants) and is eventually covered up by overburden. I'm not going to go into the details of the physical change but the reason black coal might be considered metamorphic is that it has been subjected to more pressure over time which furthers the coalification process.

The order of coalification coal:

peat -> lignite (brown coal) ->sub bituminous -> bituminous ->anthracite (very rare)

everything after lignite is black in colour.

If you need this for a report I'd probably look it up though, its been a while since I've studied coal in depth.

No, coal is not a sustainable resource due to its limited availability and negative environmental impact. Coal is a fossil fuel that releases greenhouse gases and other pollutants when burned, contributing to climate change and air pollution. Investing in renewable energy sources is a more sustainable option for the long-term.

The most abundant fossil fuel in New Zealand is coal. New Zealand has large coal reserves that are primarily used for electricity generation and industrial purposes. Oil and natural gas reserves are also present in the country, but to a lesser extent compared to coal.

The emission of toxic gas produced by Coal is enough to affect the earth's climate. Before coal mines are established they go through a phase of deforestation, which is a process of demolishing trees which affects the earth's eco-system. From here, the process of turning CO2 into oxygen cannot take place.

coal miner

1. Surface mining involves removing the topsoil and overburden to access coal seams near the earth's surface.
2. Underground mining involves tunneling underground to extract coal from deep seams.
3. Room and pillar mining entails leaving pillars of coal to support the mine roof while extracting coal in a grid pattern.
4. Longwall mining uses a shearer machine to remove coal in long horizontal slices, allowing for efficient extraction.
5. Hydraulic fracturing, also known as fracking, can be used to extract coal seam gas by injecting high-pressure fluid to fracture the coal seam and release the gas.

You can use surface mining methods such as open-pit mining and strip mining for a horizontal layer of coal close to the surface. These methods involve removing overburden to access the coal seam, making them suitable for shallow coal deposits.
