History of Life on Earth Review

What is the process of making fossils?

• Pressure
• Fossilization
• Rock Layers
• Sediment

Unaltered preservation occurs when:

• A fossil is preserved in amber, ice, or tar.
• Hard parts are replaced by silica, calcite, or iron
• A thin carbon film is left behind on the stone
• All the organic material is replaced with the minerals

• True Form Fossil
• Mold and Cast Fossil
• Carbon Film Fossil
• Trace Fossil

The process of making a carbon film fossil is:

• Unaltered Preservation
• Fossilization
• Decaying
• Carbonization

Fossils form more easily:

• On Land
• In the ocean

The farther in the ground a fossil is, the older it is:

• True
• False

A dead organism left out on earth's surface will be less likely to become a fossil than an organism that...

• gets eaten quickly

• is left in a cave

• is very large

• gets buried by sediment quickly (usually at the bottom of a water source)

When an organism's hard parts are replaced with minerals turning it into a rock/stone. Example above is permineralized wood.

• petrified (permineralized) fossil

• trace fossil

• preserved remains

• mold fossil
