What is the role of swamp plants in coal formation?

Back

Swamp plants that died millions of years ago are buried under sediment, and over time, they transform into coal.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations, often after being transported by water, wind, or ice.

How do fossils form?

Back

Fossils form when organisms are buried quickly by sediment, which protects them from decay and allows for mineralization.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of soil and rock, while weathering is the breakdown of rocks into smaller pieces without movement.
