Q:

In which type of depositional environment is coal formed?

A:

Quick Answer

Coal is formed in a swampy depositional environment that includes the remains of trees and shrubs. This swampy environment is able to bury plant life quickly before it rots. Once buried, the plant life is heated and compressed to form coal.

Full Answer

Though produced from plant life buried in the Earth for millions of years, coal plays an important role in providing the energy used by modern people. Knowing the depositional environment of coal allows geologists to search for the fossil fuel in areas where the rock layer contains those deposits. Understanding the forming process makes mining coal much more efficient.

  • Q:

    How does coal form?

    A:

    Coal forms from the physical and chemical alteration of organic peat moss. This process, called coalification, takes hundreds of years to complete. During coalification, peat moss undergoes a series of transformations as a result of bacterial decay, compaction, variations in temperature and time.

  • Q:

    How hot does coal burn?

    A:

    Coal can burn at temperatures greater than 3500 degrees F. Since burning is a chemical reaction that is dependent on the presence of oxygen, the more air there is, the higher the possible temperature that coal can reach. Inside a crucible coal can reach a temperature of 3500 degrees F.

    How is coal extracted?

    A:

    The two main methods used for coal extraction are surface mining and underground mining. The methods used to extract coal depend on the geology of the coal deposits. According to Energy Trends Insider, the amount of coal produced by one miner in one hour has more than tripled since 1978 because of improvements in mining technology and the growth in surface mining.

    What are ways to conserve coal?

    A:

    Since coal is usually burned to generate electricity for homes, it can be conserved by using energy-efficient bulbs for lighting and by conserving the energy consumed by house heaters and air conditioners. Similarly, insulating walls and cables conserves power, consequently conserving the amount of coal used.
