How is natural gas formed?

Answer 1

Natural gas is formed deep within the Earth from decomposed organic matter. Plants and marine animals die and are buried. Over time, this matter is compressed as more and more layers form over it.

When this organic material is exposed to high pressure, it is broken down into hydrocarbons and becomes natural gas or oil.

Natural gas is formed over millions of years from the remains of ancient marine microorganisms that settled at the bottom of oceans and lakes. As these organisms decayed under high pressure and heat, they transformed into organic material, which eventually turned into natural gas through a process called thermogenic decomposition. This process involves the breakdown of organic matter, such as plankton and algae, into hydrocarbons, primarily methane, under intense heat and pressure deep within the Earth's crust.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
