How are stress and faults related in earthquakes?
Stress and faults are both caused by tectonic plates.
Does stress have a big part in earthquakes?
yes cause if theres no stress u cant have an earthquake.u need stress to make a
In the lithosphere earthquakes occur when stress?
Suddenly builds up
Do earthquakes most often occur at faults that are away from plate boundary?
Earthquakes infrequently occur away from plate boundaries. Most earthquakes occur at plate boundaries because of the stress caused by the interacting plates.
Why are slope movements commonly preceded by a decrease in effective stress?
Slope movements are commonly preceded by a decrease in effective stress because there is a direct correlation between effective stress and the strength of a frictional material like soil, whereby as the effective stress decreases, the normal stress on any potential shear surface within the material also decreases. This in turn leads to a reduction in the shear strength of said surface. If this reduces to such an extent that the shear stress on the surface exceeds the frictional shear strength, movement can occur. Further to this, slopes composed of fine grained clay soils will undergo shrink and swell cycles as effective stress changes occur which can lead to strain softening behaviour and progressive failure. For more information see the related link. In particular review the equation in section 3.4 where frictional strength on a theoretical slip surface is shown to be dependent on the total normal stress (sigma n) acting on the surface minus the pore water pressure (u) or in other words the strength is directly proportional to the normal effective stress).
How do earthquakes release the energy of frictional stress?
Earthquakes release the energy of frictional stress in forms of seismic waves.
What stress causes earthquakes?
There are three types of stress tension, compression, and shearing they all cause earthquakes.
What kind of stress causes earthquakes?
Three different kinds of stress casue earthquakes, tension, compression, and sheraring From a 6th grader, Yep

Do earthquakes have weather geologic or human causes?
Earthquakes result from stress in the earth's crust, so the are of geologic origin.
How does stress can change the earth's features?
stress inside the earth causes earthquakes or faults, such as the St. Andres fault
Do earthquakes most often occur at faults that are away from plate boundary?
Earthquakes infrequently occur away from plate boundaries. Most earthquakes occur at plate boundaries because of the stress caused by the interacting plates.
What are vibrations that occur when rocks break due to stress called?
Earthquakes
What are large vibrations caused by rock breaking under stress?
Earthquakes
Earthquakes generally occur at plate boundaries where?
stress on rocks is greatest
