Normal faults accommodate extension of Earth's crust through the hanging wall moving downward relative to the footwall. The hanging wall is pulled down due to tensional forces, resulting in the crust being stretched and thinned.

What is formed when plates within the earths crust bend and crack Earth's crust?

When plates within the Earth's crust bend and crack, faults are formed. Faults are fractures in the Earth's crust where movement has occurred along the break. These movements can be either vertical or horizontal, causing earthquakes.


What is a break in the earths crust called that can move up down or sideways?

A break in the Earth's crust that can move up, down, or sideways is called a fault. Faults are classified based on the direction of movement, with different types including normal faults, reverse faults, and strike-slip faults. Movement along faults can result in earthquakes.


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 is a break in earths crust along with blocks of crust slide relative to one another?

A break in the Earth's crust along which blocks of crust slide relative to one another is called a fault. Faults are typically associated with tectonic plate movements and can result in earthquakes when stress builds up and is released. There are various types of faults, including normal, reverse, and strike-slip faults, each defined by the direction of the movement of the crustal blocks. Understanding faults is crucial for assessing seismic hazards and the geological history of an area.


Are strike-slip faults caused by tension forces?

No, strike-slip faults are typically caused by horizontal shearing forces where blocks of the Earth's crust move past each other horizontally. Tension forces usually manifest in normal faults where blocks of the crust move away from each other, causing extension.

What are the three mayor faults?

Faults are surfaces along the earths crust in which rocks have been fractured and displaced. There are three types of faults: strike-slip, normal and reverse.


How do motions affect Earth's crust?

Plate motions produce stress in Earths crust that leads to faults, mountain building, and earthquakes.


What is the term for the sudden movement of rock along fractures of faults in the earths crust?

The term is 'earthquake'.


Faults can form in which layer of the earth?

Faults are formed at the outer solid layers of the Earth. They are developed within the earths crust or Lithosphere.


When tectonic plates move slip past each other they cause in earths crust?

Faults, and plate rupture.

Do normal faults result in crustal shortening?

No, normal faults result in crustal extension, not shortening. Normal faults form as a result of tensional stresses that stretch the Earth's crust, causing one block of rock to move downward relative to the other block. Crustal shortening is typically associated with reverse faults or thrust faults, where compressional stresses push rocks together, shortening the crust.


What is a volcano fault?

Faults are made up of fractures in the earths crust. One side of the fault moves opposite of the other side.
