Either or both together. Really they are companion actions but the ratio between them will depend on the specific site. However the magma has to be intruded into the solid crust before it can break surface as an extrusive event - a volcanic eruption.

Magma that forces its way into rocks and hardens is called intrusion.
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.
(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.

Abusive, illusive,
how does knowing the prefixes in- and ex- help you remember the differ-ence between an intrusion and an extrusion?
What is the difference between intrusive and intrusive.
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 ;)
