By determining the age of fossils, scientists can reconstruct the history of life on Earth

• True
• False

In layers of sedimentary rock, the _________ layer is usually at the bottom. Each higher layer is _________ than the layers below it.

• oldest, younger
• youngest, older
• youngest, younger
• oldest, older

The millions of fossils that scientists have collected are called

• The Geologic Time Scale
• The Origin of Species
• The Fossil Record
• A really neat fossil collection

Which layer formed first?

• Rock Layer W
• Rock Layer X
• Rock Layer Y
• Rock Layer Z

What do fossils preserve?

• The entire organism including all body parts

• Fossils don't preserve anything

• Only the soft body parts like skin and organs

• Only the hard body parts like bones and teeth

What does the fossil record tell us about animal groups?

• How they have become extinct

• The fossil record doesn't provide any information about animal groups

• How they have remained the same throughout history

• How they have changed, adapted, and evolved over time

What does the fossil record tell us about the climate and environment?

• The fossil record doesn't provide any information about the climate and environment

• Information about the climate and environment of the future

• Information about the climate and environment of the present day

• Information about the climate and environment of specific places and points in time

What are trace fossils?

• Fossils that are found in sedimentary rocks

• Fossils that are preserved in amber

• Fossils that are found in museums

• Fossils that preserve other evidence of animals like burrows, droppings, footprints, nests, eggs

Amber fossils form when small creatures are trapped in

• rock

• ice

• tree sap

• mud

Why do scientists classify living things?

• It helps scientists trap species to study
• It is easier to study organisms when grouped 
• It is a good way to keep organisms calm
• It is helpful when dissecting an organism
