DeformationDeformationThis is the process where the shape of rocks change.
Caused by:
Compression- Objects are squeezed; when 2 plates collide
Tension- Objects are stretched; Occurs at divergent plate boundaries.

FaultingFaulting
Faults are cracks in the Earth’s crust.
Each side of the fault are called fault blocks.
They are named either a hanging wall or a footwall.

Normal FaultsNormal Faults
A normal fault occurs when the hanging wall moves down relative to the footwall.
Normally occurs when tectonic forces cause tension that pulls rocks apart.

Reverse FaultsReverse FaultsReverse faults causes the hanging wall to move up relative to the footwall.
These normally occur when tectonic plates cause compression that push rocks together.

Here the rocks break and move horizontally past one another.
The San Andreas Fault is a great example of this.
