States that older rocks lie below younger rocks in undisturbed sequence?
its superposition
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.
A break that separates older metamorphic rocks form younger sedimentary rocks immediately above them is a type of unconformity called an?
a nonconformity
How does the law of superposition help determine the relative age of rocks?
Radiometric dating can give us the absolute age of the rock. Trace fossils and the Law of Superposition can only provide the relative age of the rock. Radiometric dating is far more specific in formation analysis.
Why is the age of a fault younger than the rocks in which it was found?
100 year old
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
In undisturbed rocks The older rock on the bottom and the younger of the rocks are on top?
yes.
What states older rocks lie under younger rocks?
the answer is the principle of superposition
Are the Rocks near axial are younger or older than the rocks in Oregon?
What is axial?
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.
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.
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
How are rocks near continents different from rocks found near centers of seafloor spreading?
Rocks near continents(on the margins of oceanic basins) are generally older and rocks near a center of sea floor spreading are younger
How old are rocks found in Apollo missions?
The moon rocks are older then the rocks found on earth.
What is superpostioning?
The Law of Superposition states that younger layers of deposition will form on top of older layers of deposition.
