The index fossil of a type of trilobite is discovered in layer A of a set of rock layers found at three different sites of a field investigation. Which conclusion can be made about the rocks in layer A at all three sites?

• The rocks are all different ages

• The rocks are all about the same age

• The rocks were formed from melting magma

• The rocks were formed during a catastrophic event

The fossil remains of organisms with skeletons are not found in the lowest layers of rock discovered. How is the lack of fossilized skeletons in the lowest rock layers best explained?

• Organisms with skeletons did not evolve until after these rock layers formed.

• The fossils of organisms with skeletons are only found in the oldest rocks.

• Fossil skeletons are usually crushed if other rock layers are above the ones they are in.

• Organisms with skeletons live only at the highest altitudes, which is where they turn to fossils.

When examining rock layers, you will find the oldest layers at the bottom. Newer minerals and rock are piled on top and, over time, this creates distinct rock layers. This is called _______.

• The Law of Suspicion

• The Law of Horizontality

• The Law of Superposition

The mineralized remains of organisms and the rock layers in which they are found

• Fossil

• Rock Strata

• Stratigraphy
