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.
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.
How are ocean-floor rocks and sediments evidence of seafloor spreading?
because that there are younger rocks found at ocean ridges than the ones found near deep-sea trenches
Why is an igneous intrusion younger than the rocks in which it is found?
The melted rock of the igneous intrusion pushed its way into cracks and made previously existing rock weaker. The intrusions only became rock when they cooled and solidified, therefore they are younger than the rocks in which they are embedded.
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 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.

Which theory explains why rocks found on the ocean floor are younger than found on continents?
Sea Floor Spreading
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.
