There are different types of faults: reverse faults, strike-slip faults, oblique faults, and normal faults. In essence, faults are large cracks in the Earth's surface where part
These forces create stress, and they act to change the shape and/or volume of a material. The following diagrams show the three main types of stress: compressional, tensional, and shear. Stress causes the build up of strain, which causes the deformation of rocks and the Earth's crust.
