What is a horst and graben structural system?
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.
What kind of fault is the San Andrease fault?
It is a strike-slip of transform fault.
Tension pulls rocks apart and creates this?
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.
What kind of fault is represented by the eltanin and romanche fracture zones?
A Transform Fault.
Tension pulls rocks apart and creates this kind of fault?
This is known as a normal fault.
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 is a Graben and a horst?
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.

Deep faulted structures found along the axis of divergent plate boundaries is what?
You may be referring to graben structures. These are fault bounded blocks of the lithosphere that subside in regions of divergence.
What can grabens produce?
A Graben can produce a Normal Fault.
What type of fault produces horst and graben topography?
Normal / extensional faulting creates horst and graben topography.
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".
What landforms are formed from tension stress?
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.
What is the population of Lahov Graben?
Lahov Graben's population is 126.
What is terrane?
A fault-bounded area or region with a distinctive stratigraphy, structure, and geological history.
What is the definition of of fault-block?
a mass of rock bounded on at least two opposite sides by faults
When did Andreas von Graben die?
Andreas von Graben died in 1463.
