How do fossils form?

• When animals hatch from their eggs and the egg shell dissolves into the ground.

• When water fills cracks in the road, freezes and causes the road to expand.

• When an organism dies and is covered in sediment that later turns into rock.

• When scientist dig up old animals to display in museums.

How does sedimentary rock form?

• When hot, molten rock crystallizes and solidifies.

• When sediment sinks and builds up in water, compacts under more sediment, and cements over times.

• When inorganic and organic materials are subjected to high heat and pressure.

• When weathering rocks are exposed to extreme heat or cold.
