Final answer:
Coal is formed from the remains of plants and animals that lived millions of years ago. The events involved in the formation of coal occurred in a specific order over a long period of time.
Step-by-step explanation:
The events involved in the formation of coal occurred in the following order:
- Plants and trees inhabited the land and the seas about 300 million years ago.
- Tiny sea plants and animals died and were buried on the ocean floor.
- Layers of silt and sand covered their bodies.
- Organisms died and were buried on the ocean floor and in swampy areas.
- The organic matter in their bodies was subjected to great heat and pressure deep inside the crust.
- The enormous heat and pressure formed coal over millions of years.
