Which of the following terms BEST matches the definition: the geologic principle that states that in horizontal layers of of sedimentary rock, each layer is older than the layer above it and younger than the layer below it.

• Radioactive Dating

• Law of Superposition

• Half Life

• Law of Uniformitarianism

If you found an index fossil in a layer of rock in Montana and a similar fossil in a layer of rock in Texas, you would know that:

• the fossils and rock layers are the same age

• the fossils from Montana are older

• the fossils from England are older

• none of the above

According to the law of superposition, the oldest fossils are found 

• At the top of the rock layers

• Near the bottom of the rock layers

• In the middle of the rock layers

• Somewhat near the surface

How does absolute age differ from relative age?

• only absolute dating indicates which rock is older than another

• only absolute dating finds the age in years

• only relative dating finds the age in years
