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.Continue Reading
Coal formation occurs wherever there are large deposits of peat. These deposits are often located deep within the ground and take many years to accumulate. Peat deposits contain a large portion of moss but accrue many other types of organic materials as they progress through time, including plant and tree leaves, minerals, clay and even animal remains. Some deposits, particularly those situated proximately to volcanoes, contain traces of ash and charred charcoal as well.
The ingredients in coal deposits decay over time; numerous bacteria, which expedite the process, accelerate this process. The breakdown of organic matter is an important step in the process of coalification, but the peat deposit must be buried in sediment for the transformation from peat to coal to take place. Sediment burial squeezes excess water out of the peat, allowing it to take in complex hydrocarbon atoms and heat. A series of chemical reactions follows; the mixture becomes rich in carbon and releases waste products, eventually producing the end product of coal.Learn more about Natural Resources
Some of Pennsylvania's natural resources include natural gas, coal and forestry resources. Pennsylvania is the country's second-largest natural gas producer, has the country's fourth-largest coal reserves and owns the largest hardwood inventory in the country, as of 2015.Full Answer >
A savanna or a grassland biome is home to a number of natural resources, including water, livestock and lumber in tropical savannas, and coal, oil, wheat, gas, oats and livestock in temperate savannas. Some grasslands are also found to have mineral deposits, such as iron, mercury, nickel and uranium.Full Answer >
Wind power produces economic, energy and environmental benefits: it serves as a domestic fuel source, operates without burning coal and fossil fuels and provides a steady source of electricity. Wind energy comes primarily from turbines, which operate on land and offshore. Siting is another benefit of wind energy, involving turbines set up on private and public lands in order to provide electricity to residences, commercial offices and communities.Full Answer >
Some examples of limited resources include coal, nuclear, natural gas, metal ores and oil. Limited resources are basically those resources that take a relatively long time to replenish. Unlimited resources or renewable resources, such as water, wind and soil, are the opposite of limited resources.Full Answer >
