Final answer:
Reverse faults are created by compressive stresses when rocks are thrust upward as they are pushed together, often occurring in tectonic collision zones.
Step-by-step explanation:
Reverse faults are typically created by compressive stresses. These stresses occur when rocks are pushed together, and as a result, the rocks can either fold or fracture. Reverse faults are a type of fracture where the rock is thrust upward due to the compressive forces. These faults often form in regions where tectonic plates collide, causing one block of the Earth's crust to be pushed over the top of an adjacent block.
In areas with reverse faults, one can often find associated geological structures like anticlines and synclines, which are also indicative of compressive forces at work. High-pressure scenarios, such as tectonic collisions that create mountain ranges, often give rise to reverse faults. An example would be the Copper Creek Thrust Fault in the Appalachian Mountains, a result of the collision between the African and North American tectonic plates.
