What are the earths layers of rock classified by?
Earth's layers classified by their composition and their physical properties.
What does igneous rock composition mean?
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
Do all metamorphic rocks have layers?
No. The layering or foliation only occurs when there is a variation in the composition of the original rock. If the rock is homogeneous, then there will be no foliation.
How are sedimentary rock layers used by scientists to learn about the past?
Sedimentary rock layers are used by scientist help learn by the texture and shapes
A fossil that is found in the rock layers of only one geologic age and that is used to establish the age of the rock layers?
An index fossil.

What are the names of the rock layers?
stratum, or more commonly used in the plural form which is strata
A fossil that is found in the rock layers of only one geologic age and that is used to establish the age of the rock layers?
An index fossil.
Why are index fossils useful for figure out the age of a set of disturbed rock layers?
index fossils are useful for figuring out the age of a set of disturbed rock layers by index fossils are used to determine when rock layers were formed so if they were used to figure out the age of a set of disturbed rock layers than they can also figure out when they were formed .
What is the composition layers?
The composition of Ozone layer is O3
Are Aquifers rock layers?
Aquifers are permeable layers of rock that have non permeable layers of rock under them so water remains in the permeable layers
How do geologist know that rock layers are undisturbed?
the way geologist know that rock layers are undisturbed is the rock layers are folded
What is geological column used for?
the geologic column is used for identifying the layers in a rock sequence.
