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.

What are the relative ages of igneous intrusion and overlying sedimentary rock layers that dome upward?
The intrusion is younger than the overlying sedimentary rock.
If a dike is present within a rock outcrop what is its age relationship with the other rock layers?
Any igneous dike or intrusion is younger that the surrounding rock layers.
How do you know that an intrusion is younger than its surrounding rock layers?
younger over older is a phrase you can use to remember this principle.
What can disturb rock layers?
the four rock layer disturbances are: tilting, intrusion, faults, and folding
Which is older a dike or the rock layers the dike cuts across?
Dikes are always younger than the surrounding rock layers. The same holds true for any kind of intrusion. It will always be younger than anything that it is intruding into. To put it simply, you can't force an object into a bed of rock unless the bed of rock is already there.
What is the age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passed?
It is younger.
What is the The age of an intrusion of igneous rock in relation to the sedimentary rock layers through which it passes?
It is younger.

The intrusion is younger than the overlying sedimentary rock.
What is it called when rock forces itself between rock layers and is always younger then ones around it?
An intrusion (:

What is the age of an igneous intrusion in relation to the sedimentary rock layers it passes through?
It is younger than them.

Is an extrusion older or younger than the rock layer below it?
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 ;)
What do an intrusion and an extrusion tell us about the rock layers?
(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.
Could you tell me something about realative ages of rocks for a project please?
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.
What kind of rock is an intrusion made of?
An intrusion is a mass of igneous rock that forms when melted rock moves into cracks in rock layers and then cools.
What can disturb rock layers?
the four rock layer disturbances are: tilting, intrusion, faults, and folding
