Final answer:
A dip-slip fault where the upper block moves up and over the lower block is referred to as a reverse fault or specifically a thrust fault when the fault plane is shallow.
Step-by-step explanation:
A dip-slip fault in which the upper block, above the fault plane, moves up and over the lower block is called a reverse fault or a thrust fault if the angle of the fault plane is particularly shallow. Such faults are formed during periods of compression within the Earth's crust, causing the hanging wall to move upwards relative to the footwall. A specific example is the Copper Creek Thrust Fault in Tennessee, a result of the collision between the African and North American tectonic plates. In contrast, tectonic plates that slide sideways across each other, such as the San Andreas Fault in California, are characterized by lateral movement and are known as strike-slip faults.
The presence of these different types of faults and the movements associated with them can lead to significant geological formations and are essential considerations in understanding the dynamics of our planet's surface and the potential for seismic activity.
