How are stress and faults related in earthquakes?
Stress and faults are both caused by tectonic plates.
What are normal faults caused by?
Normal faults are caused by tensional stress, which occurs when the Earth's crust is being pulled apart. This causes the hanging wall to move downward relative to the footwall, resulting in the formation of a normal fault.
What types of fualts do each stress produce?
Tensional stress typically produces normal faults, compressional stress typically produces reverse faults, and shear stress typically produces strike-slip faults.
What type of stress faults produces reverse faults?
compression
Where are thrust faults?
by the stress
What is falting rock?
Faulting is caused by stress in the rock layers, the stress can break and crack the rock causing a fault. There are two types of faults a normal fault and a reverse fault.
What is the main direction of stress on blocks of rock at normql faults reverse faults and strike-slip faults?
The main direction of the stress on blocks of rock at normal faults, reverse faults and the strike slip faults usually happens at the weak areas.
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 faults are correctly associated with which types of stress?
Normal fault: Associated with tensional stress, where the hanging wall moves down relative to the footwall. Reverse fault: Associated with compressional stress, where the hanging wall moves up relative to the footwall. Strike-slip fault: Associated with shear stress, where the rocks move horizontally past each other.
Where are thrust faults located?
by the stress
What types of faults formed in compressional stress?
reverse fault
What kind of stressors on the rock cause faults?
The stress that causes strike-slip faults is produced by a shearing force and so is called shear stress.
