Extrusion is older than intrusion because, an extrusion is always younger than the rocks below it. An intrusion is always younger than the rock layers around and beneath it. Hope the answers correct ;)

How is the law of superposition is used to date fossils?
Superposition is the methodology of younger sediments being deposited over older rocks. Paleontologists can determine the evolution or extinction of a species by looking at what fossils are either present or absent in a particular sedimentary layer.
Which layers are older then layer c?
z
Why are older men called rhinos if they like younger women?
they are horny.;
What is brother in afrikaans?
A younger brother is 'bhuthi' and an older brother is 'broer' in Afrikaans
Is meat from an older or younger animal more tender?
younger due to it having less stress and generally less collagen & muscle fibres :)
In general the law of superposition states that in an undeformed sequence of sedimentary rock each layer is?
Younger than the layer below it.
Do you find older rock above or below younger rock?
The law of superposition states: in horizontal rock layers, each layer is older than the one above it and younger than the one below it.
Are layers of rock above and below the coal or older and younger?
Every layer of rock, as one moves up from the core, is younger than the one below it. This means that the layers of rock above and below the coal are different ages, with the one above younger and the one below older.
If middle layer of rock is 120 million years old what can be said about above and below layer?
top will be younger bottom older
Are the layers of rock above and below the coal older or younger?
Every layer of rock, as one moves up from the core, is younger than the one below it. This means that the layers of rock above and below the coal are different ages, with the one above younger and the one below older.
What is the defointion for the law of superstition?
the law of superstition is the geologi principle that states that in horizontal layers of sedimentary rock.Each layer is older than the layer above it and younger than the layer below it
Is the layer of rock at the bottom of a sedimentatry rock younger or older?
Older.
Is the fault older or younger than rock layer A?
older because it is at the bottom and the ones on top are younger than the bottoms
How does the age of a rock layer compare with an igneous intrusion that is through it or an igneous rock extrusion above it?
If it is above it, the rock layer came after the intrusion. if the intrusion went through the rock layer is older because they layer had to be there in order for the intrusion to go through.
Brief note on the law of superposition?
It is a law that the higher the rock layer is the younger it is. The deeper it is the older the rock layer is.
What do an intrusion and an extrusion tell us about the rock layers?
(Intrusion) You can learn how old the rock layers are around it. the rock layers around under and all around the intrusion are always older than the intrusion itself. (EXTRUSION) the layers of rock bellow the extrusion is older than the extrusion.
How the principle of superposition was used in determining the relative ags of the cross sections?
The principle of superposition states that the higher layers are younger because they must be laid down on a layer below, which is therefore older, can be used in cross-sections. Each layer, going up, is younger than all the previous layers.
