When two normal faults cause valleys to drop down on either side of a block of rock what type of landform results?
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.
How do faults affect Earth's surface?
Faults are fractures in the Earth's crust where rocks on either side have moved relative to each other. When this movement occurs, it can cause earthquakes, as the stress built up from the shifting rocks is released suddenly. Additionally, faults can create topographical features such as mountains, valleys, and plateaus due to the uplift or subsidence of the land along the fault line.
Does the geosphere effect the hydrosphere?
They don't
What type faults create mountain and valleys?
Mountain ranges are typically formed by compressional or convergent boundaries, where tectonic plates collide and cause uplift and folding of the crust. Valleys, on the other hand, can be created by various types of faults and processes, such as normal faults (resulting from tensional forces), erosion by rivers or glaciers, or subsidence of the crust.
What landforms are associated with each boundary?
Convergent boundary: associated with subduction zones, mountain ranges, and trenches. Divergent boundary: associated with rift valleys, mid-ocean ridges, and seafloor spreading. Transform boundary: associated with strike-slip faults and earthquakes.

What landforms are formed by a transform fault?
Transform faults are tectonic plate boundaries where plates slide past each other horizontally. They typically create linear features such as strike-slip fault lines, small valleys, and offset stream channels. These faults do not usually create notable landforms above the surface due to the lack of vertical movement.
What landforms do strike-slip faults form?
Strike-slip faults can create features such as valleys, mountain ranges, and even offset streams or rivers. These faults are often associated with transform plate boundaries, where two plates slide past each other horizontally. Over time, the movement along strike-slip faults can lead to the creation of new landforms and the modification of existing ones.
What landforms occur on transform boundaries?
Transform boundaries are characterized by lateral sliding of tectonic plates, resulting in faults and fractures in the Earth's crust. Some landforms that can occur along transform boundaries include strike-slip faults, valleys, and linear ridges formed by tectonic activity. These boundaries do not typically exhibit prominent landforms such as mountains or trenches like other plate boundaries.
What do you call the deep cracks in the earths crust along which the crust shifted?
Trenches if they are in zones of subduction. Falt lines are in areas of shifting plates (rubbing against or parallel)
What Types of landforms made by reverse faults?
Reverse faults create landforms such as thrust faults, fault scarps, and fold mountains. Thrust faults are characterized by large sheets of rock moving over one another, leading to the uplifting of landforms. Fault scarps are steep cliffs formed as a result of vertical displacement along the fault. Fold mountains are created by the compression and uplift of rock layers along a reverse fault, resulting in long mountain ranges with folded and contorted rock formations.
Are normal faults classified as constructive or deconstructive?
Normal faults are classified as constructive geological features. They occur in extensional tectonic settings where the Earth's crust is being pulled apart, leading to the formation of new crust as the hanging wall moves downward relative to the footwall. This process can create rift valleys and basins, contributing to the formation of new landforms.

Are there valleys on the surface of the moon?
Yes, there are valleys on the surface of the Moon, primarily formed by faults, impacts, and volcanic activity. These valleys are known as rilles or grabens and are found in various regions across the Moon's surface.

What type of landforms or activity can be found at a convergent boundary?
At a convergent boundary, landforms such as mountains, deep ocean trenches, and volcanic arcs can be found. Tectonic activity includes the subduction of one plate under another, leading to the formation of these features. Earthquakes and volcanic eruptions are also common at convergent boundaries.
