A graben is a down-thrown block which is bounded by faults along its sides. A horst is an up-thrown block which is bounded along its sides. When a horst and graben are beside each other, they are considered to be a horst and graben structural system.
A horst and graben landform results, with the raised block of rock called a horst and the dropped blocks of rock on either side called graben. This results from the extension of the Earth's crust due to tensional forces, creating a series of parallel faults.
Fault, crack, fracture, fissure, joint are all terms that could be applied to this question.In structural terms, tensile stress in the earth's crust initially creates normal faults. If the tensile stress state persists, larger scale structures such as horst and graben will develop (where graben are down thrown blocks of crust surrounded by normal faults, horsts are the upthrown crustal blocks surrounding the graben).Ultimately this may result in the formation of a rift valley and or the creation of a divergent tectonic plate boundary.
The down thrown block is known as a Graben. If the extensional stress in the crust continues, then eventually a rift valley will form. The crustal blocks on either side of a Graben are known as Horst structures. Please see the related links.
Normal faults move because of tension, which causes the hanging wall to move downward relative to the footwall. This type of faulting occurs in areas where the Earth's crust is being pulled apart, and can create features such as rift valleys and horst-and-graben structures.
The basin and range province is characterized by horst and graben topography, resulting from the presence of many normal faults. Horsts are uplifted blocks of crust, while grabens are down-dropped blocks, creating alternating mountain ranges and valleys across the region.
A graben is a down-thrown block which is bounded by faults along its sides. A horst is an up-thrown block which is bounded along its sides. When a horst and graben are beside each other, they are considered to be a horst and graben structural system.
A normal fault produces horst and graben topography. In this type of faulting, the hanging wall moves down relative to the footwall, resulting in block faulting where a horst (uplifted block) is adjacent to a graben (down-dropped block).

A horst and graben landform results, with the raised block of rock called a horst and the dropped blocks of rock on either side called graben. This results from the extension of the Earth's crust due to tensional forces, creating a series of parallel faults.
Lahov Graben's population is 126.
This will form a series of tensile features. Initially, normal faulting will occur, then horst and graben structures will form and ultimately a rift valley will develop.
Andreas von Graben died in 1463.
Andreas von Graben was born in 14##.
The area of Lahov Graben is 8,860,000.0 square meters.
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. An example would be a rift valley such as the Jordan valley (containing the dead sea) or the East African rift valley system.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.Please note that both features are NOT produce by tension, NO point on the Earth's crust can be in tension. However they do form in areas of crustal extension where the principal (maximum) stress is vertical (gravity).
The first large structures formed by tensile stress in the crust are Horst and Graben structures. If the tensile stress state is maintained, these may form into a rift valley and ultimately develop into a new mid oceanic spreading centre.
