Pressure and heat changed some of this carbon and hydrogen-rich material into coal, some into oil (petroleum), and some into natural gas.
What causes oil and natural gas to form?
Deep in the Earth, oil and natural gas are formed from organic matter from dead plants and animals. These hydrocarbons take millions of years to form under very specific pressure and temperature conditions.
What are the factors responsible for the formation of coal oil and natural gas?
They were formed over millions of years, from the remains of dead organisms: coal was formed from dead trees and other plant material. crude oil and gas were formed from dead marine organisms.
What two factors cause natural gas to form?
The combination of compression and high temperature causes the carbon bonds in the organic matter to break down. This molecular breakdown produces thermogenic methane—natural gas.
What is the starting material for oil and natural gas?
The starting material is believed to be creatures called diatoms. How was the starting material changed during oil formation? It was changed during maturation, when organisms and mud pile up on the sea floor and eventually turn to rock. The soft parts of ancient organisms are transformed into oil and natural gas.
What is the difference between the formation of coal and the formation of oil and natural gas?
Fossil fuels were formed from the fossillized remains of dead plants and animals that once lived millions of years ago. Oil and natural gas are the products of the deep burial and decomposition of dead plants and animals. … Coal comes mainly from dead plants which have been buried and compacted beneath sediments.
What is the main difference in the formation of coal vs the formation of natural gas and oil quizlet?

2) What is one main difference between the formation of oil and coal? Oil is a liquid hydrocarbon that is formed when a rock high in organic carbon is subjected to heat and pressure. Coal is a rock that is high in organic carbon, formed in low-lying wetlands.
