What are the two types of reverse faults and what is the difference?
A normal fault is a type of dip-slip fault where one side of land moves downward while the other side stays still. In contrast, a reverse fault is a type of dip-slip fault where one side of the land moves upwards while the other side stays still.
What is the difference between the two types of faults?
Normal faults form when the hanging wall drops down. The forces that create normal faults are pulling the sides apart, or extensional. Reverse faults form when the hanging wall moves up. The forces creating reverse faults are compressional, pushing the sides together.
What is the difference between reverse and normal fault?
A normal fault is one at which the hanging wall has been depressed relative to the foot wall. A reverse fault is one at which the hanging wall has been raised relative to the foot wall.
What is a reverse fault in science?
In a reverse fault, the block above the fault moves up relative to the block below the fault. This fault motion is caused by compressional forces and results in shortening. A reverse fault is called a thrust fault if the dip of the fault plane is small.
What produces a reverse fault?
Which of the following produces reverse fault?
Compressional stress
Compressional stress is when rock slabs are pushed into each other, like cars in a head-on collision. This causes reverse faults, which are the reverse of normal faults, because in this case, the hanging wall slides upward relative to the footwall. Shear stress is when rock slabs slide past each other horizontally.
What are the 3 different faults?
There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip.
What is the difference between reverse fault and normal faults quizlet?
Normal faults’ walls move away from each other. The hanging wall in a normal fault goes down and the footwall goes up. They both have hanging and footwalls. In a reverse fault the hanging wall goes up and the foot wall goes down.
How is a reverse fault different from a normal fault?
What is Reverse Fault A reverse fault is a type of dip-slip fault where one side of the land moves upwards while the other side stays still. The non-moving land is called the footwall while the side that moves is called the hanging wall. Therefore, it is the opposite of a normal fault.
Why are reverse faults called dip slip faults?
The forces creating reverse faults are compressional, pushing the sides together. They are common at convergent boundaries. Together, normal and reverse faults are called dip-slip faults, because the movement on them occurs along the dip direction — either down or up, respectively.
Where are reverse and thrust faults most likely to occur?
Reverse and Thrust Faults. A convergent plate boundary is a zone of major reverse and thrust faults. In fact, subduction zones are sometimes referred to as mega-thrust faults. Reverse and thrust faults also occur in other settings where the crust is being compressed, such as the Transverse Mountain Ranges, just north of Los Angeles.
What does it mean when a fault goes up instead of down?
So when one side of the fault does go up instead of down, it is called a reverse fault. It is working against gravity. We also have names for the two sides of the fault. The fault does not go straight up and down. It is at an angle, which means that one side of the fault hangs over the other.
