Fossil fuels are made from?

Question

A. minerals.
B. plants and animals.
C. inorganic matter.
D. water and gases.

Answer 1

B - after they've been decomposing for hundreds of
thousands or millions of years.

Answer 2

The correct answer is most of the above. Petroleum (oil) is made of hydrocarbons. Hydrocarbons are not all formed from plants and animals -- it rains liquid methane (natural gas) on the Saturn's moon Titan and nobody calls that "fossil" fuel so hydrocarbons can be natural minerals thus A is a correct answer. But decaying plant and animal remains can also form methane so B is also correct. I'm not sure about C but D is half right because methane and other petroleum components are gaseous at standard temperature and pressure.

Answer 3

The answer they want is B. But the real answer is the Sun, because the Sun allowed the plants to grow and/or the animals to grow, and subsequently die, be buried and turn into fuel. However, some theory say that fossil fuel is not really from organic matter, but I am sure your school is not so advanced as to consider anything but standard rhetoric (research the Internet for other theory).

Answer 4

B. Plants and animals under high temperature and pressure gets fossilised and get converted into carbon and hydrocarbons. The process takes thousands to millions of years.

Answer 5

by decomposition of plants & animals under special temperature

Answer 6

b) plants and animals

Answer 7

umm , Fossils

that would be 'b' the other cannot fossilize

Answer 8

the answer is B.

Answer 9

B

Answer 10

B...
