Peat forms during glacial periods, when the polar ice sheets grow and the sea level falls. Then, when the ice melts and the sea floods into the swamps, the peat is preserved, locked away beneath new marine sediment. In some places, the rock record attests to dozens of these repeating marine and nonmarine layers, known as cyclothems.

With too much heat, the oil breaks down to make methane. This gas is also produced as coal forms. Coal, as a solid, mostly sits where it was formed. Eventually, if the rocks above it are eroded so that it is exposed at the Earth's surface, the coal itself may be eroded away, and either "eaten" by bacteria, or buried in new rocks. And ...

This process is referred to as 'coalification'. ... Initially peat, the precursor of coal, was converted into lignite or brown coal a coal type with low organic 'maturity'. ... As this process continued, further chemical and physical changes occurred causing these coals to become harder and more mature, at which point they are classified as ...

Specifically, peat compacts to form solid rock through a process called lithification, producing lignite (brown coal, a lowquality form of coal). With increasing heat and pressure, lignite turns to subbituminous coal and bituminous coal. Lignite, subbituminous coal, and bituminous coal are considered sedimentary rocks because they from from ...

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]

When did the coal deposits of the eastern United States begin to form? What were environmental conditions like at that time? It began to form about 300 million years ago during a time geologists call the carboniferous period. the environmental problems were they fell into swamp water, which was low in oxygen

For the peat to become coal, it must be buried by sediment. Burial compacts the peat and, consequently, much water is squeezed out during the first stages of burial. Continued burial and the addition of heat and time cause the complex hydrocarbon compounds in the peat to break down and alter in a variety of ways.

Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.

It is important to remember, though, that coal takes a very long time to form from peat because the peat has to become very compact. It is estimated that for every 1 vertical foot of coal mined from Kentucky, it took 10 vertical feet of original peat material to produce it. Answer 2: Coal is mainly out of plant material, but not exclusively.

Once "the oxygen in the peat has been depleted, anaerobic bacteria . . . continue the process of degradation." After the plant material turns into peat, it is buried by sediment. Over millions of years, the pressure from above and heat from the earth squeeze and evaporate any residual moisture from the peat and it is transformed into coal.
