Is an intrusion younger than its surrouding rock layers?
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.
When waves cut completly through a headland what is formed?
When waves cut completely through a headland, a feature called a sea cave is formed. Sea caves are formed by the relentless erosion of waves gradually wearing away the weaker rock layers of a headland. Over time, the waves create openings and cavities that can extend deep into the headland.
Unlike other types of plutons a dike forms?
In fractures that cut across rock layers
Forms when waves erode softer rock that underlies harder rock?
A wave cut platform is formed. == ==
Why is the age of a fault is younger than the rocks in which it is found?
How could the rock be faulted if it came after the faulting? It wouldn't be there to fault. So therefore, what ever the fault cuts through, it must be younger than it in order for it to be able to cut the rock in the first place.
Name a rock which can be split into very thin layers?
Most rocks can be cut into thin layers. A rock that can be split into thin layers is shale.
How was the lapstone monocline formed?
The monocline took place gradually, as the nepean river was able to cut down into the rock layers at a rate that allowed it to retain its course (which at present cuts into the monocline)
Sheets of igneous rock that cut across other rocks layers?
Dykes.

What does rock composition mean?
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
