Answer 1

Answer:

a)a natural fuel such as coal or oil, that was formed millions of years ago from dead animals or plants in the ground

b)How Oil and Gas Deposits Are Formed

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.

c)There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are:

Answer 2

Explanation:

a) a natural fuel such as coal or oil, that was formed millions of years ago from dead animals or plants in the ground

b) Natural gas deposits are often found near oil deposits. Deposits of natural gas close to the Earth's surface are usually dwarfed by nearby oil deposits. Deeper deposits—formed at higher temperatures and under more pressure—have more natural gas than oil. The deepest deposits can be made up of pure natural gas.
