If the situation is as simple as the one you have stated, it isn't difficult. Meanwhile, many faults displace laterally, either in compression or tension so that it can appear that younger rocks overlie older ones. See the law of super-position. Compressive faults generally force younger rocks below older, but not always. See subduction zones. Then see ophiolite suites.
The reason the crosscutting feature is always younger than the rock layers it cuts across, is because the rock layers had to be present before the features could cut across them.
The layers were in place before the faulting took place, so they would be older than the fault.
relative dating
Younger.
No, older.
New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.
angular unconformity
According to the geologic Law of Superposition, in undisturbed rock strata, the deepest rock layers are always the oldest. Accordingly, a fossil found in a lower layer of undisturbed rock would be the older.
Faults are breaks in the crust where the crust has moved. The types of dip-slip faults are normal and reverse faults. In both of these, the movement is along the slope of the fault. Sudden movements along these faults can produce fault scarps. Layers of rock being misaligned is evidence of fault movement. Fault creep is caused by slow movement along the fault.In a normal fault, the plates are moving away from each other. This is due to tension. When the fault moves, the footwall rises relative to the hanging wall. Normal faults occur at divergent boundaries, such as ocean ridges. Normal faults can produce fault-block mountains.In a reverse fault, the plates are moving towards each other. This is due to compression. Here, the footwall falls relative to the hanging wall. A thrust fault is a special type of reverse fault, where the angle is shallow. Reverse faults occur at convergent boundaries, like subduction zones.A strike-slip fault is where the two plates move horizontally past each other. The force between them is called shearing. This type of fault is often called a transform fault, because they occur at transform boundaries.
The compositional layers of the earth are the crust, mantle and core. The physical layers are the lithosphere, asthenosphere, mesosphere, outer and inner core.
A crosscutting feature is always younger than the rock layers it cuts through because the feature always forms after the rock layers have been formed, making the rock layers older.
Because the rocks have to be there first, all faults are younger than the rocks they end up cutting across. In regard to sedimentary rock layers, each layer is younger than the one below it.

A fault is necessarily younger than faults it cuts through; it could not have happened if the layers were not there first.
Younger layers are deposited on top of older layers, whether the layer is sedimentary or volcanic. Occasionally faults may result in overthrusts, where a series of older layers may be pushed over the top of younger layers. But this is rare. In general, the older layers will be the lower layers.
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.
Folds are the when the rock layers bend. Faults are breaks in the rock layers. Folds are called anticlines and synclines. Faults are called reverse faults, normal faults, or strike-slip faults.
A body of magma that cuts through (and across) adjacent rock. Similar to a secondary vent but it does not strike through the surface. It then hardens and forms rock. It is always younger than the rocks which surround it.
An intrusion (:
Younger than all three sediments.
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 ;)
The Law of Superposition states that younger layers of deposition will form on top of older layers of deposition.
