An intrusion is younger than its surrounding rock layers. An intrusion needs another rock to cut through it, which is referred to as a cross-cutting relationship.
An intrusion is younger than its surrounding rock layers if it cuts across them. This is because the intrusion must have been deposited after the surrounding layers were already in place. Additionally, any fossils or index minerals found in the intrusion would be younger than those in the surrounding rock layers, providing further evidence of relative age.
The igneous intrusion is typically younger than the overlying sedimentary rock layers in a dome structure. The intrusion must have occurred after the deposition of the sedimentary layers and caused them to deform and dome upward due to the force of the molten rock pushing through.
A fault or an intrusion of magma is always younger than the rock layers around and beneath it. This is because faults cut across existing rock layers and intrusions of magma cool and solidify after the surrounding rock layers have already formed.
This statement refers to Steno's Principle of Superposition, which states that in an undisturbed sequence of rock layers, the youngest layer is on top and the oldest is on the bottom. Therefore, any fault or intrusion cutting through these layers must be younger than the rock it is cutting through.
The dike is younger than the rock layers it intrudes into. Dikes form when molten rock (magma) is injected into fractures in existing rock layers and then solidifies, cutting across the surrounding rock. This means that the dike is a later geological event compared to the layers it cuts through.

It is younger.
It is younger.
An intrusion (:
It is younger than them.

Extrusion is older than intrusion because, an extrusion is always younger than the rocks below it. An intrusion is always younger than the rock layers around and beneath it. Hope the answers correct ;)
(Intrusion) You can learn how old the rock layers are around it. the rock layers around under and all around the intrusion are always older than the intrusion itself. (EXTRUSION) the layers of rock bellow the extrusion is older than the extrusion.
When you look at a rock that has undisturbed layers, the bottom layers are older and the upper layers are younger. Anytime a rock layer crosses another (ie. an intrusion), the crossing layer is younger.
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.
