What is the final step of fossilization?

• Minerals around the skeleton preserve the bone.

• The animal is covered of layers of dirt and sediment.

• Wind and water erosion expose the fossil to the surface.

• Over time, layers build pressure that turn the layers into stone.

How are Sedimentary Rocks formed?

• A. Cooling and Hardening
• B. Melting and heating
• C. Compacting and Cementing
• D. Time

In order for a fossil to form, which of the following events must happen FIRST?

• Slowly, minerals in the water replace the bone.

• Sediment covers the bone.

• An organism dies.

• The bone is no longer a bone, but a rock copy.

Which of the following are geologic processes?

• Volcanic eruptions

• Erosion

• A plants life cycle

• Cloud formation

• Mountain Building

When an organism dies it can be buried in layers and layers of sediment due to....

• Erosion

• Weathering

• Deposition

• Igneous Rock Formation

Cold temperatures slow down decay. This means that frozen fossils...

• ...only bones will remain

• ...soft and hard parts of the fossil will remain

• ...the fossil will not form but be destroy by the cold temperatures
