- Faults are breaks in the crust where the crust has moved. The types of dip-slip faults are normal and reverse faults. In both of these, the movement is along the slope of the fault. Sudden movements along these faults can produce fault scarps. Layers of rock being misaligned is evidence of fault movement. Fault creep is caused by slow movement along the fault.
- In a normal fault, the plates are moving away from each other. This is due to tension. When the fault moves, the footwall rises relative to the hanging wall. Normal faults occur at divergent boundaries, such as ocean ridges. Normal faults can produce fault-block mountains.
- In a reverse fault, the plates are moving towards each other. This is due to compression. Here, the footwall falls relative to the hanging wall. A thrust fault is a special type of reverse fault, where the angle is shallow. Reverse faults occur at convergent boundaries, like subduction zones.
- A strike-slip fault is where the two plates move horizontally past each other. The force between them is called shearing. This type of fault is often called a transform fault, because they occur at transform boundaries.
The seismic waves created by the release of rock stress is usually recorded as an earthquake.

Rock above a fault that moves downward?
It moves downward.. the force behind it is tension
What happens at a reverse fault?
Where fault blocks collide into each other. The most prominent example of this are the Himalayan Mountains formed by the collision of the Indian plate and the Eurasian Plate making what is called a folded mountain.
What happens to glucose as it moves from consumer to consumer?
people die get over it!
What are the faults?
There are 3 main types of faults 1. Normal 2. Strike slip 3. Reverse(Thrust) In a normal fault the foot wall stays in place while the hanging wall moves DOWNWARDS In a strike slip the tectonic plate(s) slide past each other horizontally In a reverse fault, the hanging wall gets pushed UPWARDS over the foot wall (The pictures are in the reverse order)
What happens to an object when it moves closer to convex lens?
No, the closer an object is to the lens, the more the spherical it is.
What happens to the earth's crust moves suddenly to a fault?
A sudden movement of the Earth's crust is called an earthquake.
When a plate moves suddenly what happens?
An Earthquake happens.
What happens to the hangwall when a normal fault occurs?
it moves downwards
What happenes if the earth's crust moves suddenly along a fault?
A sudden shift of the earth's crust along a fault could result in an earthquake.
What happens along a fault?
the hanging wall moves down relative to the footwall
What happens if the earths crust moves suddley along a fault?
The sudden movement could result in an earthquake.
What is the difference between a normal fault and reverse fault?
A Reverse fault is happens when tectonic forces cause compression that PUSHES rocks together. Normal fault happens when tectonic forces cause tension that PULLS rocks apart.Normal fault is when the hanging block moves down relative to foot block wall where as the reverse fault is formed when the hanging block wall moves up relative to the foot block walls a result of tension and compression force respectively
What happens when friction on opposite side of a fault is high?
High friction on opposite sides of a fault can cause stress to build up in the rocks. When the stress exceeds the strength of the rocks, it can result in an earthquake as the rocks suddenly shift along the fault line.
What fault moves rock downward?
a normal fault
In A Blank Fault The Hanging Wall Moves Up Relative To The Footwall?
In a normal fault, the hanging wall moves down relative to the footwall, whereas in a reverse fault, the hanging wall moves up relative to the footwall.
What kind of fault moves because it is under tension?
A normal fault moves because it is under tension. In a normal fault, the hanging wall moves down relative to the footwall due to the pulling apart of the Earth's crust, creating space and tension that cause the fault to move.
This type of fault occurs when rock above the fault moves upward at the fault line?
A reverse fault occurs when rock above the fault moves upward at the fault line. This type of fault is associated with compressional stress where the hanging wall moves up relative to the footwall. Reverse faults are common in regions undergoing compression, such as convergent plate boundaries.
