Coal and petroleum are called fossil fuels because they are formed from the remains of dead plants and animals that lived millions of years ago. Here are the steps explaining why:

1. Millions of years ago, plants and animals died and fell to the bottom of the sea. Over time, they were covered by layers of sand and mud.

2. Over millions of years, these layers of sand and mud became so heavy that they compressed the dead plants and animals into a layer of rock.

3. The heat and pressure from the earth's crust turned these remains into coal and petroleum.

4. These fossil fuels are then extracted from the earth and used as a source of energy.

5. The term "fossil fuel" comes from the fact that these resources are made from the fossils of ancient plants and animals.
