How does a rift valley from?
A rift valley is formed by the depression of a block of the earth's crust between two faults or groups of faults, of approximately parallel orientation.

How do faullt-block mountains form?
along nearly parallel normal faults.
What is the definition of graben?
It is a depressed block of land, bordered by parallel geological 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.
Mountains that form when large areas of Earth gradually move skyward as a unit are called mountains?
Horst mountains are the type of mountains that form when large areas of Earth gradually uplift as a unit. This uplift occurs as a block of crust is forced upward between two parallel faults, resulting in a tilted plateau or range. This process can happen due to tectonic forces or the slow cooling and contraction of Earth's interior.
When two normal faults cause valleys to drop down on either side of a block of rock what type of landforms results?
A graben forms when two normal faults cause valleys to drop down on either side of a block of rock. This landform is characterized by a depressed area between two parallel faults, with the central block lowered relative to the surrounding blocks.
What are the two type of faults can result mountains and why?
The two types of faults that can result in mountains are thrust faults and normal faults. Thrust faults occur when older rock is pushed on top of younger rock, causing uplift and mountain formation. Normal faults occur when tensional forces cause one block of rock to drop down relative to another block, creating valleys and mountain ranges.
What is an upraised block bounded by two reverse faults?
An upraised block bounded by two reverse faults is a geological feature known as a "horst." In this structure, the block of crust is elevated relative to the surrounding terrain, which is typically lowered due to the activity of the reverse faults on either side. The reverse faults indicate compression in the Earth's crust, leading to the uplift of the horst. This formation is commonly found in regions experiencing tectonic forces, such as mountain ranges.
Lower block of crust between two normal faults?
It is called Graben
How are block mountains formed?
Block mountains are typically formed through the process of faulting, where large rock blocks are uplifted along faults in the Earth's crust. This uplift can be caused by tectonic forces, such as the collision of tectonic plates or the movement of faults. Over time, erosion can further shape the block mountain into its characteristic steep, rugged form.
