Formation of Coal
Coalification is a long-term process that converts dead materials such as plants and flowers into coal. During geological eras, the Earth was once covered in lush woodlands, particularly in wetland areas. In these areas, acidic water and dirt now prevent the decomposition and oxidation of dead plants. Peat is formed as a result of this process. The coalification process began when bogs accumulating peats held significant amounts of carbon, which was later completely buried by sediments.
Now, millions of years of pressure and heat have caused water, carbon dioxide, and methane to escape, leaving the matter with carbon content. The amount of heat and pressure used to turn dead stuff into coal determines the coal’s gradation. Sub-bituminous, bituminous, and anthracite coals are generated under high temperature and pressure, whilst Lignite is formed under relatively mild conditions.
Coal and Petroleum
Coal and petroleum are the consequence of the decomposition of ancient plant life that existed millions of years ago. These decomposing plant materials began to accumulate, eventually producing peat. Heat and pressure from geological processes turned these minerals into coal over time. They are also known as fossil fuels because they are made up of essential fossils.
Coal and Petroleum NCERT class 8 and class 10 are important chapters in the biology syllabus of both these classes. In this article, we will discuss coal and petroleum in detail.
