How many fault are there?
There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.

What is a crack in the earth called?
Faults are cracks in the earth’s crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small.
What are the 3 types of faults?
Three types of faults. There are three kinds of faults: strike-slip, normal and thrust (reverse) faults, said Nicholas van der Elst, a seismologist at Columbia University’s Lamont-Doherty Earth Observatory in Palisades, New York.
What are examples of normal faults?
A normal fault occurs where the deeper part of the crust is pulling away from an overlying part. A reverse is, well, just the reverse. An example of a normal fault is the 240-mile (150-kilometer) long Wasatch Fault underlying parts of Utah and Idaho, again caused by the Pacific plate driving under western North America.
What are some names of faults around the world?
Fault Types Normal fault. A dip-slip fault in which the block above the fault has moved downward relative to the block below. Reverse fault. A dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block. Strike-slip fault. A fault on which the two blocks slide past one another.
What is an example of a normal fault?
An example of a normal fault is the 240-mile (150-kilometer) long Wasatch Fault underlying parts of Utah and Idaho, again caused by the Pacific plate driving under western North America.
