What can you tell from undisturbed rock layers?
You can tell the age of the layers. The bottom layer is the oldest and the top is the youngest. When the layers are disturbed they tend to get bent and messed up and you cannot tell the age
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.
What does the law of superposition tell us about rock layers?

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.
