How are horsts and grabens similar?

Answer 1

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.

Answer 2

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.

Answer 3

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).

Answer 4

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.
