What type of fault results from compression stresses that push rock together?

• A. Strike-slip fault
• B. Thrust fault
• C. Normal fault
• D. Transform fault

Answer: (B)

The answer is a thrust fault because it specifically occurs in areas where compression stresses act on rock formations, causing them to buckle and push against each other. In this type of fault, one block of rock is forcibly pushed over another, resulting in a steeply inclined fault plane. Thrust faults are commonly found in regions experiencing tectonic plate collision, where the compressional forces are strong enough to overcome the strength of the rocks. This mechanism of faulting leads to the formation of mountain ranges and complex geological structures. Understanding thrust faults is important in fields such as geology and seismology, as they can be associated with significant seismic activity.
