Coal (fuel source)

Coal seam gas extraction can impact the environment through potential groundwater contamination, habitat disruption, and air pollution. The drilling process can release methane, a potent greenhouse gas, and other air pollutants. There is concern about the long-term effects of coal seam gas extraction on water resources and ecosystems.

The largest coal producer in the world is China, followed by India, the United States, and Australia. China alone produces about half of the world's coal, primarily used for electricity generation and industrial purposes.

Coal forms mostly in tropical or temperate regions because it requires abundant plant growth and slow burial to undergo the necessary transformation into coal. The Arctic region has a colder climate and limited plant growth, making it unsuitable for coal formation.

The deepest coal mine in the world is in Ukraine at a depth of around 3,500 feet.

It could contribute to acid rain falling on the forest.

The wood is converted to anthracite (coal) through various stages. lignite, subbituminous,bituminous,anthracite are the major coal types formed these are ranked based on the presence of carbon ,hydrogen and oxygen content

Coal is found in underground mines in locations around the world, with significant deposits in countries such as the United States, China, India, and Australia. Oil is typically found in underground reservoirs beneath the Earth's surface, with major oil-producing regions including the Middle East, North America, Russia, and South America.

Coal is formed from the remains of plants that lived and died millions of years ago. These plants accumulated in swampy environments and were buried under layers of sediment. Over time, heat and pressure transformed the plant material into coal, which is then found in underground coal seams.

Coal is formed from plant matter that gets buried and compressed over millions of years. As layers of sediment build up on top of the plant matter, the increasing pressure and heat cause the organic material to undergo biochemical changes, eventually transforming into coal. Over time, geological processes can bury these layers deeper inside the Earth's crust.

Nearly two-thirds of the world's known coal reserves are located in just four countries: the United States, Russia, China, and Australia.

Coal is sourced from underground mines or surface mines located in various regions around the world. The top coal-producing countries include China, India, USA, and Australia. The type of mine used depends on factors such as depth of the coal seam and cost effectiveness.

Increases in greenhouse gases are causing our planet to trap more heat and thereby warm up. CO2 is one of the primary greenhouse gases, by quantity. Additional atmospheric CO2 comes primarily from the oxidation reduction of coal and petroleum. Coal is mostly carbon, and burning coal combines this carbon with atmospheric oxygen to form CO2. Humans currently release over 40 billion tons of CO2 into the atmosphere each year, where it lingers, inevitably resulting in climate change.

Coal has been forming in the Earth for millions of years, with some coal deposits dating back to over 300 million years. The process of coal formation involves the accumulation of plant material in swampy environments, which over time gets buried and compressed to form coal deposits.

Coal is found in Antarctica because millions of years ago, when the continent was covered in lush vegetation, plant material accumulated and was eventually buried under sediment. Over time, the pressure and heat transformed the plant material into coal deposits.

Yes, coal mining and burning contribute to air and water pollution and the release of greenhouse gases, leading to climate change and environmental degradation. Additionally, the extraction of coal can disrupt ecosystems, harm wildlife, and create health hazards for nearby communities.

1. Materials needed: (1.25 m) copper road , salt and coal .

2. How to make to GI earth pit :

a. Dig a hall in the dirt ground at least for 1m depth.

b. Install a PVC pipe of 1m length and 10 cm width inside this pit.

c. Install the copper road in the middle of the PVC pipe and start to make layers

of 10 cm in sequence of salt once and coal till the PVC pipe is filled you must

keep the road tip over the ground at least for 10 cm so you could get

connection to your ground system.

d. When you get done of the mix layers of the salt and coal.. you need to take

the PVC pipe off to get contact between the system and the ground.

e. You could joint the end tip of the copper road to the facility earth system.

And then you will get a good earthing system .. for large facilities with high load consuming power you could make 3 pits the same way with 3 copper roads joint them as triangle by a copper cable and use any one of the 3 points as earth main point for the system ..

Hope I could Help somebody with this ..

Most creationists believe that coal formed rapidly during the Biblical flood around 4,500 years ago. They argue that the layers of dead vegetation were quickly buried and compressed, leading to the rapid formation of coal seams.

No, burning coal and oil does not reduce the weight of the Earth. The mass of the Earth remains constant, regardless of the burning of fossil fuels. However, burning fossil fuels does contribute to global warming and environmental damage.

Coal is fine grained, lack of visible texture.

The states with the most surface coal mines in the United States are Wyoming, West Virginia, and Kentucky. These states have a long history of coal mining and significant reserves of coal, contributing to their high number of surface mines.

we dont say a fix depth of underground mine becoz that is depends on geological conditions of the area where we mined and also depends the property of mineral which have to be mined. Companies engaged in this industry extract coal that lies 200 to 1,000 feet below the earth's surface, though some mines are as deep as 2,000 feet.

There are thousands of coal mines operating around the world today, with major producers being China, the United States, India, and Australia. However, the number of active coal mines fluctuates due to factors like market demand and regulatory changes.

for the same reason you might be surprised to find a fly in an ice cube.

Coal is made from compressed plant matter and how exactly did plants grow on the surface of an ocean. (as there is no land mass beneath the arctic)

Coal mining is good because it is used to get a very important natural resource, coal. Coal is used in many things and without coal mining we could not do those things. They were used on the first trains and in stoves to keep old log houses warm.

Montana mainly mines sub-bituminous coal. This type of coal has a lower energy content and higher moisture content compared to bituminous coal, making it less desirable for some applications.
