Scarp

It should be noted that movement along a fault need not be vertical to produce a scarp. Try the activity below to see just how this works.

(or Thrust belt)

The folding and deformation of great masses of rock are actually very common phenomena in the Earth's crust. Although these processes are generally associated with faults, we will largely be ignoring them in this module because of the complexity they can add. Just keep in mind that rocks can be somewhat elastic, and can deform in such a way to accomodate movement within the Earth's crust. We may model the crust as entirely rigid, but given the right conditions, even rocks can bend.
