Q1. What is a normal fault? A1. A normal fault is a type of geological fracture caused by tension, resulting in the rocks on either side of the fault plane moving down in relation to each other.

Q2. How does a normal fault form? A2. A normal fault forms when the Earth’s crust is stretched, which can be caused by tectonic plate movements or extensional tectonic forces.

Q3. What is a reverse fault? A3. A reverse fault is a type of geological fracture caused by compression, resulting in the rocks on either side of the fault plane moving up in relation to each other.

Q4. How does a reverse fault form? A4. A reverse fault forms when the Earth’s crust is squeezed, which can be caused by tectonic plate movements or compressional tectonic forces.

Q5. What are the differences between normal and reverse faults? A5. Normal faults are caused by tension and result in the rocks on either side of the fault plane moving down in relation to each other, while reverse faults are caused by compression and result in the rocks on either side of the fault plane moving up in relation to each other.

Q6. How can you tell which type of fault is present in a particular area? A6. By examining the strike and dip of the fault plane, you can tell which type of fault is present.

Q7. What is a hanging wall and a foot wall? A7. The hanging wall is the block of rock that moves up relative to the foot wall. The foot wall is the block of rock that moves down relative to the hanging wall.

Q8. What kind of hazards are associated with reverse and normal faults? A8. Both types of faults can cause strong shaking and landslides, and in intense cases, tsunamis.

Q9. Are normal and reverse faults always visible? A9. No, normal and reverse faults can be hidden deep below the Earth’s surface, making them difficult to detect with the naked eye.

Q10. What kinds of activities can help prevent damage from normal and reverse faults? A10. Groundwater management, seismic resistant building design, seismic monitoring, and early warning systems can all help reduce the risk of damage from normal and reverse faults.
