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.

What evidence did cross-cutting relationships give geologists?
Cross-cutting can give insight to whether or not a certain layer is older or younger than what is cross-cutting it. Say if a dike was cross-cutting layer A, then layer A is older than the dike.
What a cross cutting relationship?
Cross cutting relationships define rock formations in geology. When magma enters cracks and crevices in existing rocks and cools it forms what is called an igneous intrusion. The principal of cross cutting relationships means that the igneous intrusion is always younger than the rock it cuts across.
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.
What is the Principle of Cross-Cutting Relationships?
Cross cutting rock is younger than the rock surrounding it.
Are only sedimentary rocks used for relative age determination?
No, igneous rocks can be used in this way based on the fact that an igneous intrusion will be younger than the material through which it passes. This is part of the principle of cross cutting relationships.
Does the law of cross cutting relationships involve sedimentary rock only?
No. Cross-cutting igneous intrusions could occur in any pre-existing rock type.
The idea that an igneous rock is younger than the rocks it has intruded is stated in the law of?
Cross Cutting Relationships
According to the principle of cross-cutting relationships an intrusive rock body is .?
Younger than the rock it intrudes into
According to the principle of cross-cutting relationships an intrusive rock body is?
Younger than the rock it intrudes into
What is the relationship between rocks and their cross cutting intrusions?
The cross cutting intrusions can be used to determine the age of the rocks.
What do the principles of cross-cutting relationships teach us?
Layers that cut across the most other features are youngest.
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).
