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.
Do normal faults result in crustal shortening?
No, normal faults result in crustal extension, not shortening. Normal faults form as a result of tensional stresses that stretch the Earth's crust, causing one block of rock to move downward relative to the other block. Crustal shortening is typically associated with reverse faults or thrust faults, where compressional stresses push rocks together, shortening the crust.
When two normal faults cause valleys to drop down on either side of a block of rock what type of landforms results?
A graben forms when two normal faults cause valleys to drop down on either side of a block of rock. This landform is characterized by a depressed area between two parallel faults, with the central block lowered relative to the surrounding blocks.
What type of fault causes fault-block mountains?
Fault-block mountains are caused by normal faults, where blocks of the Earth's crust are tilted and uplifted along a fault line. As the hanging wall block moves downward relative to the footwall block, it creates a steep mountain range with a characteristic block-like appearance.
What are the two type of faults can result mountains and why?
The two types of faults that can result in mountains are thrust faults and normal faults. Thrust faults occur when older rock is pushed on top of younger rock, causing uplift and mountain formation. Normal faults occur when tensional forces cause one block of rock to drop down relative to another block, creating valleys and mountain ranges.

Lower block of crust between two normal faults?
It is called Graben

Crustal shortening is typically associated with reverse faults or thrust faults, where compressional stresses push rocks together, shortening the crust.
What type of fault causes land to move downward?
Normal fault. The fault itself does not cause the sinking but is part or an effectof the process. The sunken block between two faults is called a "graben".
How a fault block is created?
by two normal faults
The land between two normal faults may be uplifted to form?
Normal Faultin a normal fault, the hanging wall slips down relative to the footwallfootwall- the rock that lies belowhanging wall- the block of rock that lies abovenormal fault- tension in Earth's crust pulls rock apart which causes normal fault2. The Land Between Two Normal Faults Moves Upward To Form What?is a Fault - Block Mountain.
How is a fault-block mountain created?
by two normal faults
What is the normal force exerted by the table on a block when a downward force is applied to the block while it is at rest on the table?
The normal force exerted by the table on a block at rest is equal in magnitude but opposite in direction to the downward force applied to the block.
When two normal faults cause valleys to drop down on either side of a block of rock what type of landforms results?
A graben forms when two normal faults cause valleys to drop down on either side of a block of rock. This landform is characterized by a depressed area between two parallel faults, with the central block lowered relative to the surrounding blocks.
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.
