Fossil Fuels

Fossil Fuels are

• pieces of rock that have been compacted many times

• rock that contains 50% plant and animal remains

• metamorphic rock

• fuels that form from the remains of plant and other organisms that were buried and altered over million of years

All fossil fuels are formed from the reamins of living things. Which factor determines the type of fossil fuel that the remains become?

• how quickly the remains were covered by water.

• the type of remains, such land plants or ocean organisms

• the amount of heat that the fossil fuel received underground

• the type of roc that surrounded the fossil fuel underground.

The coal we use today began forming millions of years ago. What was the first step in the formation of coal?

• Plankton died and sank to the ocean floor

• Rivers deposited sediments along their banks

• Decomposerd broke down the remain of plants and animals

• The remains of plants were covered with water at the bottom of swamps

Natural gas forms beneath the ocean. How is it possible that reserves of natural gas are found beneath dry land, including in Texas?

Suppose one of the plants dies. Which step must occur next for the remains of the plants to change to coal?

• The remains must be digested by worms or other decomposers
