When there is an igneous intrusion and a fault line which one is younger?
That depends! If the fault line cross cuts the igneous intrusion causing the intrusion to be displaced on either side of the fault and forming a broken mass of rock within the intrusion known as a fault breccia then the fault is younger than the intrusions, as the intrusion must have already existed for the fault to cause it's displacement. If on the other hand the igneous intrusion cross cuts the fault and is un-deformed then it is probable that it is younger than the fault.
Why is the age of a fault is younger than the rocks in which it is found?
How could the rock be faulted if it came after the faulting? It wouldn't be there to fault. So therefore, what ever the fault cuts through, it must be younger than it in order for it to be able to cut the rock in the first place.
Magma that forces its way into rocks and hardens is called a extrusion or fault or unconformity or intrusion?
Magma that forces its way into rocks and hardens is called intrusion.
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
Why is the age of a fault younger than the rocks in which it was found?
100 year old
What is the relative age of fault or igneous intrusion that cuts through an unconformity?
If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.
What is the relative age of a fault or igneous intrusion that cuts through an unconformity?
If a fault or intrusion cuts through an unconformity, the fault or intrusion is younger than all the rocks it cuts through above and below the unconformity.

Which is younger a fault or sandstone?
One is not necessarily older than the other. It depends on the context. A fault running through any rock must be younger than that rock.
Is a layer younger or older than the layers it cuts through?
A fault is necessarily younger than faults it cuts through; it could not have happened if the layers were not there first.
How are cross cutting relationships used in?
Cross cutting relations are used in relative dating because you can see which layers were deposited before or after the fault occured. The same way, when a fault cuts through a rock, or when magma intrudes and crystallizes, we can assume that the fault or intrusion is younger than the rocks affected.

It states that fault cut through rocks is always younger than the rocks itcuts?
Yes

Magma that forces its way into rocks and hardens is called intrusion.
What do faults tell geologists about the relative ages of rock?
A fault must be younger than the rock it cuts through.
How is the fault younger than three rock layers?
The rock layers that a fault passes through had to have already existed for them to break and create a fault. This is analogous to the door panel of your car had to have already existed for it to bend and create a dent.
What is the law of cross cutting relationship?
Prior relationship related answer: Don't be cross cutting across other peoples relationships because you will find your self stuck in the middle. Geological answer: The law of cross cutting relationships states that an igneous intrusion or fault that cuts across another rock stratum must be younger than said stratum.
