What is a trench between two parallel faults in earth's crust called?
A trench between two parallel faults in the earth's crust is called a graben. Grabens are formed by the downward movement of blocks of land between normal faults.
Which type of fault occurs when a portion of rock moves downward leaving the other place with the overhang?
parallel normal faults.
What are normal reverse and strike slip faults?
Normal reverse and strike-slip faults are types of geological faults that occur due to tectonic forces. Normal faults occur when the Earth's crust is extended, causing one block of rock to move downward relative to another, typically forming steep angles. Conversely, reverse faults result from compressional forces, where one block of rock is pushed up over another, creating a steep incline. Strike-slip faults involve lateral movement, where two blocks slide past each other horizontally, often associated with transform plate boundaries.
What are normal faults caused by?
Normal faults are caused by tensional stress, which occurs when the Earth's crust is being pulled apart. This causes the hanging wall to move downward relative to the footwall, resulting in the formation of a normal fault.
What is an uplifted block bounded by two reverse faults?
An uplifted block bounded by two reverse faults is known as a horst. It is a raised area of land between two parallel faults where the central block has moved upward relative to the blocks on either side. Horsts are common features in regions where tectonic forces cause the Earth's crust to compress and deform.
What is a trench between two parallel faults in earth's crust called?

Which type of occurs when a portion of rock moves downward leaving the other in place with an overhang?
parallel normal faults.
A graben is bounded by what kind of fault?
A graben is bounded by normal faults, where the hanging wall moves downward relative to the footwall. This results in the central block of land sinking between the two bounding faults, forming a trough-like depression in the Earth's crust.

parallel normal faults.

How does a rift valley from?
A rift valley is formed by the depression of a block of the earth's crust between two faults or groups of faults, of approximately parallel orientation.
A rift valley is the reverse of this type of mountain.?
fault block
What is a Valley formed where ridge appears to be torn apart?
A valley formed where a ridge appears to be torn apart is known as a graben. This geological feature is created by the downward displacement of a block of land between two parallel faults. The movement along the faults causes the land to sink and create a linear valley.
What is the Long narrow area that has dropped between two faults?
That is called a graben. It forms when the land between two parallel faults drops down due to tectonic forces pulling it apart. Grabens are common in areas with significant tectonic activity, such as along plate boundaries.
What forms in cracks or along faults?
Minerals can precipitate within cracks or faults, forming veins. Water can also accumulate in these features, leading to the formation of geodes or stalactites/stalagmites. Additionally, sediments may accumulate in cracks and faults, forming breccia or fault gouge.
