coal oil natural gas

Question 1: How are these energy sources formed?

Question 2: What is the relationship between these energy sources and the sun?

Problem 3: Energy depletion

What coal brings to us

Information 1: There are traces of plants on the coal

Information 2: Coal is mostly sandwiched in rocks

Information 3: Coal is buried in layers underground.

Information 4: Hundreds of millions of years ago, plants flourished on the earth

How is coal formed? What is it made of?

The formation of oil and natural gas

Regarding the origin of oil, most people currently advocate the theory of organic formation. Ancient lower animals and plants (mainly plankton with the largest reproduction volume) were deposited together with sediment in low-lying shallow seas, bays or lakes, first forming organic silt. This organic silt is covered with new sediments, creating an environment that is cut off from the air. As the sediments in low-lying areas continue to settle and the sediments continue to thicken, the pressure and temperature experienced by the organic silt also continue to increase, under the influence of aerobic bacteria, temperature, pressure and other factors. Gradually turn into dispersed oil droplets, which gradually move into porous oil storage rock layers (sandstone and conglomerate) under pressure, and gather in certain geological structures (such as dome structures). This is An oil field was formed.

Natural gas is a combustible gas stored underground in porous rock or petroleum, and its origin is similar to that of petroleum. Because it is lighter than oil, it is often located on top of oil.
