A Graben is the result of a block of land being downthrown producing a valley with a distinct scarp or "escarpment" on each side. An example would be a rift valley such as the Jordan valley (containing the dead sea) or the East African rift valley system or the Rio Grande Rift in New Mexico and west Texas.
Grabens often occur side-by-side with Horsts. (see related link below).
A Horst is the reverse of a Graben, it forms as a residual elevated block of land left between the formation of two parallel Graben. An example of a Horst would be the Black Forrest mountains, and the Ruwenzori Range.

Horsts and grabens are both landforms created by the process of faulting in the Earth's crust. A horst is a raised block of crust between two parallel faults, while a graben is a lowered block of crust between parallel faults. Both features are typically found in regions where tectonic forces are actively pulling the Earth's crust apart.

∙ 10y agoBoth horsts and grabens occur from tensional stress and normal faulting. Also, both of them occur between two normal faults.
-----------------------------------------------------------------------
Please note that both features are NOT produce by tension, NO point on the Earth's crust can be in tension (or the Earth would fly apart). However, they do form in areas of crustal extension where the principal (maximum) stress is vertical (gravity).

∙ 9y agoHorsts are mountains, while grabens refer to valleys. In geology, these are found in regions that lie between normal faults and are higher than the area beyond the faults.

What land features are associated with the process of orogenesis at divergent boundaries?
At divergent boundaries, land features associated with orogenesis include rift valleys and mid-ocean ridges. These features form as tectonic plates move apart, causing the crust to stretch and fracture, leading to the creation of new crust and landforms.
What term describes down-dropped blocks of crust bounded by steeply dipping normal faults?
These down-dropped blocks of crust are called grabens. Grabens are formed by the extensional forces that cause the crust to stretch and create space for the down-dropped blocks between the steeply dipping normal faults.
What are uplifted blocks called?
Uplifted blocks are called horsts. They are characterized by being elevated relative to the surrounding areas due to tectonic forces, often created by the movement of faults.
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.
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.
Are horsts and grabens bounded by normal or reverse faults?
Normal

What can grabens produce?
A Graben can produce a Normal Fault.
What is the balcones fault zones?
The Balcones Fault Zone is a geological fault line in Texas that runs from the southwest part of the state to the north-central region. It is known for causing seismic activity and creating unique features in the landscape, such as the Balcones Escarpment. The fault zone is significant for shaping the geology of central Texas and influencing groundwater resources in the region.
What are Horsts and Grabens and where an they be found?
Both structures are formed as a result of large scale (regional) normal faulting. Graben are "valley" features and Horsts are "mountain" features.A Graben is the result of a block of land being downthrown producing a valley with a distinct scarp or "escarpment" on each side.

What kind fault would create a mountain range?
A convergent boundary fault, where two tectonic plates collide and push against each other, would create a mountain range. The immense pressure and stress from the collision force the Earth's crust to fold and push upwards, forming the mountains.
A graben is bounded on each side by?
A graben is bounded on each side by normal faults and upthrown crustal blocks known as horsts.
What term describes down-dropped blocks of crust bounded by steeply dipping normal faults?
These down-dropped blocks of crust are called grabens. Grabens are formed by the extensional forces that cause the crust to stretch and create space for the down-dropped blocks between the steeply dipping normal faults.
What is a horst and graben structural system?
A horst and graben structural system is a type of tectonic feature where blocks of the Earth's crust are uplifted (horst) and down-dropped (graben) along parallel faults. Horsts are the raised blocks, while grabens are the lowered blocks in between. This system is typically associated with extensional tectonic settings where the crust is being pulled apart.
What has the author Peter Eric Johnson written?
Peter Eric Johnson has written: 'The origin of the Chiwaukum graben, Chelan County, Washington' -- subject(s): Grabens (Geology)
How were the mountains the great basin across Utah and Nevada formed?
The mountains of the Great basin were formed by plate spreading in that part of the North American Continent. What happens is, as a plate spreads apart, fault blocks start to form. Two blocks on either side will rise while the one in the middle sinks. The rising blocks are called horsts, the the sinking blocks are called grabens.
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.
