Origin of petroleum. Millions of years ago, the earth was populated with plants and animals. Much of that life was located in or adjacent to ancient rivers, lakes, and sea. As plants and animals died, their remains settled to the bottom of these bodies of water. Ancient rivers carried mud and sand that buried the organic material.

WhatsApp: +86 18838072829Petroleum is an ingredient in thousands of everyday items. The gasoline that we depend on for transportation to school, work, or vacation comes from crude oil. A barrel of petroleum produces about 72 liters (19 gallons) of gasoline, and is used by people all over the world to power cars, boats, jets, and scooters.
WhatsApp: +86 18838072829Explain the process of formation of petroleum. Answer Petroleum was formed from plants and animals living in sea. When they died, their bodies settled at bottom of ocean. These get covered with sand and clay. Due to high temperature, high pressure and absence of air. in millions of years, these dead organisms get converted into petroleum

WhatsApp: +86 18838072829Petroleum is a fossil fuel that naturally occurs in the liquid form created by the decomposition of organic matter beneath the surface of the earth millions of years ago. These fossil fuels are then refined into usable substances such as petrol, kerosene, etc. It is formed by the combination of hydrocarbons and other substances, mainly sulphur.
WhatsApp: +86 18838072829The precise chemical structures vary depending on the type of fossil fuel (coal, oil, or natural gas). The molecules in coal tend to be larger than those in oil and natural gas. Coal is thus solid at room temperature, oil is liquid, and natural gas is in a gaseous phase. Specifically, coal is a black or dark brown solid fossil fuel found as ...
WhatsApp: +86 18838072829Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbonbased material approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coalbearing rock units appeared about 290360 million years ago, at a time known as the Carboniferous or "coalbearing" Period.
WhatsApp: +86 18838072829It is the coal with the lowest carbon content. The carbon content is only about 6070 %. It is formed during the younger stages of coal formation and thus has a lower carbon content. Due to the less amount of carbon, it is not fully black in colour and is somewhat brown. Lignite is used in electricity generation and in fertilizer production.
