Zones of immobile rock along faults are called "fault gouge" or "fault zones." These areas consist of crushed and finely ground rock that form due to the intense pressure and friction during fault movement. They can be characterized by reduced permeability and strength compared to surrounding rock, influencing the behavior of earthquakes and the stability of geological formations.

What is the zones of immobile rock along faults?
The zones of immobile rock along faults, often referred to as "fault gouge" or "fault core," are regions where the rock has been subjected to intense stress and deformation, leading to a reduction in its ability to move. These zones typically contain crushed and fragmented rock, which can inhibit slip during an earthquake. They act as barriers to movement, contributing to the overall stability of the fault until the accumulated stress exceeds the strength of the rock. Understanding these zones is crucial for assessing earthquake risk and fault behavior.
What often happens along large cracks called faults bat the edge of the earth plates?
Earthquakes
What group of minerals form along faults?
vein minerals form between faults.
What are three ways in which geologist use seismograph?
They map faults, detect changes along faults, and develop a method of predicting earthquakes
Earthquakes result when forces push what along faults in earths lithosphere?
Earthquakes result when forces push plates along faults in the Earth's lithosphere. These plates are comprised of the crust and a portion of the upper mantle.

What is a region of numerous closely spaced faults called?
A region of numerous closely spaced faults is called a fault zone. These fault zones can vary in size and complexity, with the potential to generate earthquakes due to the movement of the Earth's crust along these faults.
What kind of fault is represented by the eltanin and romanche fracture zones?
The Eltanin and Romanche fracture zones are oceanic transform faults. These types of faults occur at the boundary between two tectonic plates where they slide past each other horizontally. The movement along these faults can cause earthquakes and contribute to the overall plate tectonics process
Once the elastic limit of rock is passed they break and move along surface called?
faults
When rocks break, they move along surfaces called?
When rocks break, they move along surfaces called faults or fractures. These are planes along which the rock layers have shifted relative to each other due to stress in the Earth's crust. Movement along these surfaces can result in earthquakes.
What are some connections between plate boundaries forces and faults?
Plate boundaries experience different types of forces, such as compression, tension, and shear, which can cause faults to form. In compression zones, faults like reverse and thrust faults can develop due to the plates being pushed together. In tension zones, normal faults form as plates are pulled apart. Shear forces along transform boundaries can create strike-slip faults.
Where does faults break?
Faults break along zones of weakness in the Earth's crust, where tectonic plates interact. These breaks occur due to accumulated stress that exceeds the strength of rocks, causing them to fracture and slip. The movement can happen suddenly during earthquakes or gradually over time, resulting in various types of faults, such as normal, reverse, or strike-slip faults. Faults can be found in diverse geological settings, often along 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)
A sharp cliff caused by sudden movements along dip-slip faults is called a .?
A sharp cliff caused by sudden movements along dip-slip faults is called an earthquake. It causes the ground to shake for several seconds.
Why are faults responsible for significant amounts of weathering?
Faults act as zones of weakness in the Earth's crust, allowing water and air to penetrate deeper and increase the rate of weathering. The movement along faults also creates stress on rocks, leading to fracturing and breaking down of the material into smaller pieces. Additionally, the repeated movement along faults exposes fresh rock surfaces to weathering processes.
What is a break or crack along which rocks moved called?
A break or crack along which rocks move is called a fault. Sudden motion along the faults result to earthquakes.
Faults undergoing movement that is horizontal and parallel to the strike of the fault surface are called?
Faults which appear to have displaced rock strata horizontally are called strike slip faults. The two blocks that have been displaced move in opposite directions along the fault line.
