What does the Law of Superposition state?
In a sedimentary rock structure, the younger rock layers are on the bottom, while the older rock layers are on the top.
In a sedimentary rock structure, all rock layers are usually the same age.

Why are index fossils helpful to geologists? Check all that apply.
They are larger than all other fossils and therefore are used as a reference.
They can provide the exact date for when the rock formed.
They can provide a range of dates for when the rock formed.
Observe the diagram. Which fossil is the index fossil?
Fossil A
Fossil B
Fossil C
Fossil D
Check off the two characteristics for identifying index fossils within rock layers.
The fossil is found in multiple rock layers.
The fossil is only found in one rock layer.
More than one of the fossil can be found in the layer.
Only one of the fossils can be found in the layer.
