Unit 3 Pre-Test / Post-Test

What would be the first thing we do at the beginning of a new unit?

• Post Test

• Pre Test

• Current Event

• Fire Drill

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.

How do rock layers form?

• New layers form on top of existing rock layers, lower layers are older and higher layers are newer.

• Rock layers form around organisms to leave space for fossil formations.

• Scientist form rock layers in their labs.

• Rock layers form as rocks go through the rock cycle.
