Answer 2

Answer:

Millions of years ago, the earth was populated with plants and animals. Much of that life was located in or adjacent to ancient rivers, lakes, and sea. As plants and animals died, their remains settled to the bottom of these bodies of water. Ancient rivers carried mud and sand that buried the organic material. As layers of organic material continued to build up, the oxygen supply to the lower layers eventually was cut off and decomposition slowed down. The thickness of such layers grew to 100s of feet over the time.[1]
