Model of a Normal Fault
Attached is a model below.
When rocks crack and shift as a result of being pulled apart, this is a typical fault. The rocks migrate along the fault when the area is stretched. There are earthquakes with every movement.
1. Which way did point B moved relative to point A?
Move upward making point D & C in the same level
2. What happened to rock layers X, Y, and Z?
Move to another layer or misaligned. it becomes broken or offset by the fault
3. Are the rock layers still continuous?
Not anymore. it is already broken by fault
4. What likely happened to the river? The road? The railroad tracks?
River – it will create tiny waterfalls/slightly elevated.
Road – elevated
Railroad – elevated
Earth's fault movements have an impact on rivers, roads, and train tracks. The fracture zone between rock blocks that results in relative movement between them is known as a fault. The river settles to create a lake or pond in a reversal fault.
5. Is this type of fault caused by tension, compression or sharing?
It formed a plateau. While not usually, faults can be found close to plate borders, and each form of fault is frequently linked to particular kinds of plate motions.
Nevertheless, you may probably identify every kind of fault movement connected to every kind of plate boundary.
- Divergent (tensional) boundaries are frequently linked to normal faults.
- Convergent (compressional) boundaries are frequently linked to thrust faults.
- Transform (sliding) borders are commonly linked to strike-slip faults.
Severe earthquakes and their catastrophic aftershocks are among the nature's most terrifying and destructive events. A quick release of tension that has collected over a long period of time is what causes an earthquake, which is a sudden movement of the Earth.
The enormous plates that make up the surface of the Earth have been gently moving over, beneath, and past each other for hundreds of millions of years as a result of plate tectonic forces. The movement might occasionally be gradual.
When this happens, the plates are unable to release the building energy because they are trapped together. The plates release when the energy builds up sufficiently. If the earthquake takes place in a populous location, it could result in several fatalities, serious injuries, and significant property damage.
