The Formation of Fossil Fuels- text book steps

Question 1

Name step one of how fossil fuels are formed.

Answer 1

The remains of plants and animals are deposited underwater, in swamps or along the coast, They begin to decay.

Question 2

Name step two of how fossil fuels are formed.

Answer 2

Soil and mud are washed into the water. They form layers on top of the plant and animal remains.

Question 3

Name step three of how fossil fuels are formed.

Answer 3

More layers lead to increased pressure; the increased pressure, over a long time, changes the remains into coal, oil and gas. More layers of soil and mud are added. These new layers increase and add pressure to the layers below.
Over a long time:
– The lower layers of sand and mud are compacted and form sedimentary rock.
– The pressure of layers above changes the remains into fossil fuels.
