Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Oil and natural gas result from
A
the migration of complex carbohydrate molecules to nonporous rock formations.
B
the decay of tiny marine organisms that accumulated on the ocean floor millions of years ago.
C
squeezing rock in a huge vise.
D
the burning of high-sulfur, low grade uranium.
Explanation: 

Detailed explanation-1: -Millions of years ago, algae and plants lived in shallow seas. After dying and sinking to the seafloor, the organic material mixed with other sediments and was buried. Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels.

Detailed explanation-2: -Oil and natural gas result from the decay of tiny marine organisms that accumulated on the bottom of the ocean millions of years ago. Most of the world’s fossil-fuel reserves are made up of coal Asia and North America are particularly rich in coal deposits.

Detailed explanation-3: -Origin of Oil and Natural Gas Oil and natural gas are formed underground, over several to tens of millions of years, from prehistoric organisms decomposed by high subterranean heat and microorganisms. Oil and gas collect in formations underground, where they are prone to accumulate, to form oil/gas fields.

Detailed explanation-4: -Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth’s crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels.

Detailed explanation-5: -Years ago, when prehistoric animals and plants died, layers of rock and dirt gradually buried them. Over millions of years, heat and pressure from Earth’s crust decomposed these organisms into one of the three main kinds of fuel: oil (also called petroleum), natural gas, or coal.
