definition of reverse fault thrust fault
Answer (1)
Answer:A reverse fault and a thrust fault are both types of faults where the hanging wall (the block of rock above the fault plane) moves upward relative to the footwall (the block of rock below the fault plane). Here's a breakdown: Reverse Fault:Definition: A reverse fault is a type of fault where the hanging wall moves upward relative to the footwall. This movement is caused by compressional forces pushing the rocks together.Angle: The fault plane of a reverse fault is typically inclined at a steep angle (greater than 45 degrees).Result: Reverse faults shorten the Earth's crust and can create mountains and other uplifted features. Thrust Fault:Definition: A thrust fault is a type of reverse fault where the fault plane is inclined at a low angle (less than 45 degrees). This means the hanging wall moves up and over the footwall.Angle: The low angle of the fault plane is what distinguishes a thrust fault from a typical reverse fault.Result: Thrust faults can also shorten the Earth's crust and create mountains. They are often found in areas of intense compression, such as mountain ranges. Key Differences:Angle: The main difference between a reverse fault and a thrust fault is the angle of the fault plane. Reverse faults have steeper angles, while thrust faults have shallower angles.Displacement: Thrust faults typically have a greater displacement (the amount of movement along the fault) than reverse faults. In Summary:Both reverse faults and thrust faults are caused by compressional forces and result in the hanging wall moving upward relative to the footwall. The main difference is the angle of the fault plane, which is steeper in reverse faults and shallower in thrust faults.
