Why is a fault younger than the rocks in which it is found?
Faults are the result of "brittle deformation". This means that they occur in rocks which are not molten. A rock has to be solid before it can be faulted, and hence the rock must have formed before the fault could form within it.
Why is the age of a fault younger than the rocks in which it was found?
The fault must be younger because it cuts across the existing rocks, indicating that it formed after the rocks were already in place. This suggests that the faulting event occurred after the deposition of the rock layers.
What is the relative age relationship of faults to the rocks they cut?
Faults are younger than the rocks they cut through, as they are formed after the rock units. The offset layers or rocks along a fault help geologists determine the relative age relationship between the fault and the surrounding rocks.
Why is an igneous intrusion younger than the rocks in which it is found?
An igneous intrusion is younger because it forms after the surrounding rocks have already solidified. Magma forces its way into the existing rock layers, and once it cools and solidifies, it is considered younger than the surrounding rocks. This relationship helps geologists determine the sequence of geological events.
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.

How does the age of a fault compare to the age of the rocks that are actually faulted?
The fault will be younger than the rocks it faulted (cross-cutting relationships).
It states that fault cut through rocks is always younger than the rocks itcuts?
Yes
Why is the age of a fault in a rock younger in which it is found?
Given the law of superposition and assuming an undisturbed "pancake" stratigraphy each successive layer is younger than the the underlying one. Therefore, the fault is the 'youngest' feature in the system because the rocks need to form first in order for a fault to truncate them.
