What states older rocks lie under younger rocks?
the answer is the principle of superposition
How are the laws of superposition and crosscutting relationships used to determine the age of rocks?
They are used to determine the relative ages of rocks by stating that younger rocks lie above older rocks, and that rocks that cut through a layer are younger than the existing layer.

How can older rocks be found above younger rocks in a cross section?
Older rocks can be found above younger rocks in a cross section due to processes like faulting and folding. Faulting occurs when rock layers break and move along a fault plane, causing older rocks to be displaced above younger rocks. Folding occurs when rock layers are subjected to compressive forces, resulting in older rocks being pushed up and over younger rocks. These geologic forces create the observed order of rock layers in a cross section.
Is it true Older sedimentary rocks are usually found beneath younger ones?
If the strata layers are folded or tilted then the older rocks can be found on top of the younger rocks in a cross-section.

What is it called when younger rocks are layered on top of older rocks?
superposition
What older rocks lie under younger rocks?
the answer is the principle of superposition
What states older rocks lie under younger rocks?
the answer is the principle of superposition
In undisturbed rocks The older rock on the bottom and the younger of the rocks are on top?
yes.
What is supersition?
It says the younger rocks lie above older rocks if the rocks have not been disturbed .
States that older rocks lie below younger rocks in undisturbed sequence?
its superposition
What is superpostioning?
The Law of Superposition states that younger layers of deposition will form on top of older layers of deposition.
How are the laws of superposition and crosscutting relationships used to determine the age of rocks?
They are used to determine the relative ages of rocks by stating that younger rocks lie above older rocks, and that rocks that cut through a layer are younger than the existing layer.
What are older rocks that lie under younger rocks called?
You may be referring to an "outlier" which is an area of older rocks surrounded by younger ones due to faulting and erosion removing layers of younger rocks and forcing older ones up into them. You may also potentially be referring to a xenolith. This is a fragment of older material that has not melted that is trapped within lava or other younger igneous material.

What are the reative age relationship of faults the rocks they cut?
Faults are always younger than the rocks they cut. They cannot be older that the rocks they are cutting, because the rocks would not be there.
