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?
The relative age of a fault or igneous intrusion that cuts through an unconformity is younger than the unconformity but older than the rock it cuts through. This is because the fault or intrusion must have formed after the deposition of the rock layers below the unconformity but before the deposition of the rock layers above the unconformity.
What do faults tell geologists about the relative ages of rock?
A fault must be younger than the rock it cuts through.
Did the fault occur before or after the igneous intrusion?
To determine whether the fault occurred before or after the igneous intrusion, geologists typically analyze the relationships between the rock layers and the intrusion. If the fault cuts through the igneous rock, it indicates that the fault occurred after the intrusion. Conversely, if the intrusion is found within the fault zone or is displaced by the fault, it suggests that the fault predates the igneous intrusion.
Is the fault older or younger the rock layer A Explain?
To determine whether the fault is older or younger than rock layer A, we can use the principle of cross-cutting relationships. If the fault cuts through rock layer A, it is younger than that layer, as it must have formed after the rock was deposited. Conversely, if rock layer A is found to be disrupted by the fault, then the fault is older. Therefore, examining the relationship between the fault and rock layer A is key to establishing their relative ages.
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?
The relative age of a fault or igneous intrusion that cuts through an unconformity is younger than the unconformity but older than the rock it cuts through. This is because the fault or intrusion must have formed after the deposition of the rock layers below the unconformity but before the deposition of the rock layers above the unconformity.
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.
Which river cuts through the Grand Canyon as it flows through Arizona to the Gulf of California?
The Colorado River.
What do faults tell geologists about the relative ages of rock?
A fault must be younger than the rock it cuts through.
Explain how scientists use the law of crosscutting relationships to determine the relative ages of rock layers and a fault that cuts through the layers?

Is it Arnold's fault of the budget cuts?
I think so as Arnold make taxes cuts
A fault or body is younger than any other body of rock it cuts through according to the law of what?
The law of cross-cutting relationships.
A fault or body of rock is younger than any other body of rock it cuts through according to the law of?
The law of cross-cutting relationships.
Two important geological faults in the US?
The New Madrid fault systems extends 120 miles southward from the area of Charleston, Missouri, and Cairo, Illinois, through New Madrid and Caruthersville, following Interstate 55 to Blytheville and on down to Marked Tree, Arkansas. It crosses five state lines and cuts across the Mississippi River in three places and the Ohio River in two places. The San Andreas Fault in California is about 810 miles long, and the Cascadi Fault just offshore from Oregon and Washington is about 650 miles long. (Sorry for the finger-check - it should be the Cascadia 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.
If a fault occurs in an area where rock layers have been folded what type fault would it be?
What is the relative age of a fault that cuts across three horizontal sedimentary rock layers?A. The fault is older than the middle layer. B.The fault is younger than all the layers it cuts across.C. The fault is the same age as the top layer. D. The fault is older than all the layers it cuts across == ==
