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.
Both 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).
See related link below.
Horsts 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.
Horsts and grabens
By plate tectonics. Continental collision compresses, folds, faults and lifts the land. Crustal tension stretches the basement rock, causing down-warping and faulting, grabens, etc.
It's really unclear what you mean. They're similar to simple sugars. They're similar to hexoses. They're similar to aldoses.
They are plains
The landforms created by faults are Horst and Graben which forms the Block mountains and associated Valleys.
Normal
Horsts and grabens
it made up of normal faults, grabens and horsts
A Graben can produce a Normal Fault.
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.

Thrust faults will do this - the alps. So will normal faults - horsts
A graben is bounded on each side by normal faults and upthrown crustal blocks known as horsts.
Mountains formed by block fault movements are called horsts and valleys so formed are called graben.Examples of horsts are:Vosges Mountains in FranceBlack Forest in GermanyRwenzori Mountains (also called the Mountains of the Moon) in UgandaExamples of graben are:The Great Rift Valley of AfricaThe Rhine VallyHowever please note that ALL mountains contain a significant number of important faults.
Peter Eric Johnson has written: 'The origin of the Chiwaukum graben, Chelan County, Washington' -- subject(s): Grabens (Geology)
Rift basins are depressions within the crust and lithosphere that are associated with extensional tectonics. The presence of active normal faulting itself, creates the accomodation space for sedimentary infill within grabens and half graben structures.
The surface of the moon contains mainly dust, rocks, and craters. There are also areas with mountains, valleys, and large plains called maria, which are formed from ancient volcanic activity. Additionally, the moon's surface has no atmosphere, water, or organic material.
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.
