Movement along faults often produces sharply angled rock fragments termed?
fault breccia
Differences between a fault and a fold?
Folds are the when the rock layers bend. Faults are breaks in the rock layers. Folds are called anticlines and synclines. Faults are called reverse faults, normal faults, or strike-slip faults.
What is it called when faults move gradually rather than suddenly?
Faults are breaks in the crust where the crust has moved. The types of dip-slip faults are normal and reverse faults. In both of these, the movement is along the slope of the fault. Sudden movements along these faults can produce fault scarps. Layers of rock being misaligned is evidence of fault movement. Fault creep is caused by slow movement along the fault.In a normal fault, the plates are moving away from each other. This is due to tension. When the fault moves, the footwall rises relative to the hanging wall. Normal faults occur at divergent boundaries, such as ocean ridges. Normal faults can produce fault-block mountains.In a reverse fault, the plates are moving towards each other. This is due to compression. Here, the footwall falls relative to the hanging wall. A thrust fault is a special type of reverse fault, where the angle is shallow. Reverse faults occur at convergent boundaries, like subduction zones.A strike-slip fault is where the two plates move horizontally past each other. The force between them is called shearing. This type of fault is often called a transform fault, because they occur at transform boundaries.
What is released when rock moves along a fault?
Seismic waves are released when rock moves along a fault. These waves are the ones that cause earthquakes.
What faulting in earthquakes?
A fault is a break in Earth's crust along which blocks of rock slide relative to one another. A fault can occur within a tectonic plate's boundaries. Boundaries between tectonic plates are always faults.
How are earths faults different from your faults?
Your faults are flaws in your personality. Earth's faults are cracks in the ground along which blocks of rock move.

How can faulting act as a construction force?
Rock moves upward along faults to form a mountain range.
Huge igneous rock structures have zones of weakness called?
joints. These are fractures in the rock where there is no displacement along the fracture. Joints can create pathways for fluids to move through the rock and can affect the stability and weathering of the structure.
Once the elastic limit of rock is passed they break and move along surface called?
faults
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 common along strike-slip faults?
Common features along strike-slip faults include horizontal movement of rock blocks, offset of rock layers, fault scarps, and the presence of transform boundaries at plate margins. These faults are associated with lateral movement of adjacent rock masses along a fault plane, with minimal vertical displacement.
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 is the relationship between faults and joints?
A joint is a crack in rock; a fault is a crack in rock along which the rocks have been displaced.
What is the term for the sudden movement of rock along fractures of faults in the earths crust?
The term is 'earthquake'.
