What type of Natural Resources are Coal and Petroleum? Definition, types and Example
Fuels such as Coal and petroleum form very deeply below the Earth's surface under high temperature and high-pressure conditions for a very long period. Under these conditions, fossilized organic matter undergoes chemical conversion to form Coal on land and Petroleum underwater. Petroleum and Coal fall in the category of fossil fuels because they are formed from the preserved remains of organisms that lived millions of years ago, and people use them as fossil fuels. Fuels like Petroleum and Coal have been beneath the Earth's surface for a long time. CBSE has added a whole chapter in the Class 8 Science Syllabus to make students aware of fossil fuels.
Coal: Coal is a combustive black or brownish-black sedimentary rock rich in carbon and hydrocarbons. Coal is categorized as a nonrenewable energy source because it takes millions of years to form. Coal includes the stored energy of plants that lived in wetland forests hundreds of millions of years ago.
What are the uses of Coal? Coal seems to be one of the cheapest and essential sources of energy. Here is the list of some practical uses of Coal. Domestic Use (Cooking food or Room Heating) Electricity Generation Production of Steel As fuel for different types of Industries Gasification and Liquefaction
Types of Coal: Coal is a black diamond and is classified mainly into four categories. Those are: 1. Anthracite Coal: Anthracite is the purest form and highest rank of Coal. It is a complex, brittle, black shiny coal, often called hard Coal, holding a high
percentage of designated carbon and a lower portion of volatile matter. Anthracite coal is used for heating homes and in gas production. 2. Bituminous Coal Soft charcoal that burns with a smoky yellow flame. Bituminous Coal is the most common form of Coal. It has a high sulfur content,
