What do rock layers that break but do not move form?
A Fold (anticline or syncline) - but it is not a fault. A geological Fault is a break in the rock, with the rock on one side moved relative to that on the other..
What happens when a fault moves suddenly?
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.
Is fault a common noun or a action verb?
The word 'fault' is a common noun and an action verb, a word for an act. Example uses: Noun: The fault was found in the ignition wiring. Noun: The roots growing in the rock fault had made it more severe. Verb: I can't fault your reasoning, you just arrived at the wrong conclusion. Verb: It's easy to fault others when we haven't been in their situation.
What happens when the temperature of rock rises above its melting point?
When the temperature of a rock rises above its melting point it turns into magma, usually found in the mantle (found below the Earth's crust).
What is destructive erosion?
It is where mountainsides and such lose a lot of rock and dirt, etc., which all moves down, and the mountain decreases in size and mass.
What fault moves rock downward?
a normal fault
What fault rock above the fault surface moves downward in relation to rock below the fault surface?
This kind of fault is called a normal fault and is usually a sign of crustal extension.
What is a block of rock that lies below the plane of a fault?
A block of rock below the plane of a fault is known as the hanging wall. It is the rock mass that is located above the fault plane and typically moves downward relative to the footwall during fault movement.
When the rock above the fault surface moves down relative to the Rock below the fault surface what kind of fault?
This is described as a normal fault.
This type of fault occurs when rock moves downward at the fault line?
A normal fault occurs when rock is pulled apart, causing one block of rock to move downward relative to the other. This displacement is due to tensional forces acting on the earth's crust, causing the hanging wall to drop relative to the footwall along the fault plane.
When the rock above the fault surface moves down relative to the rock below fault surface what kind of fault forms?
This is described as a normal fault.
When the rock above the fault surface moves down relative to the rock below the surface what kind of fault forms?
This is described as a normal fault.
Which type of fault occurs when a portion of rock moves downward leaving the other in place with an overhang?
A normal fault occurs when a portion of rock moves downward relative to the other in place. This type of fault is caused by tensional forces pulling the rock mass apart, resulting in the hanging wall moving down relative to the footwall.
When the rock above the fault surface moves down relative to the rock below the fault surface what kind of faults form?
This is described as a normal fault.
Which type of fault occurs when a portion of rock moves downward, leaving the other in place with an overhangreversethruststrike-slipnormal?
reverse
What is the hanging wall of a fault?
The hanging wall is the block of rock located above the fault plane. It moves downward in a normal fault and upward in a reverse fault during faulting events. It is named "hanging" because in underground mining, it appears to hang over the miners' heads.
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.
