Earthquakes are the result of the formation of new faults within the lithosphere or the movement of older pre-existing faults.
More information:
Faults are large fractures or cracks that form in the Earth's lithosphere. They can range in size from metres to 100's or 1000's of km.
Faults form within the lithosphere due to stress. As stress increases the lithosphere initially begins to deform elastically (like a spring being squashed or an elastic band being stretched). When the stress exceeds the strength of the lithosphere, a brittle failure occurs. Brittle failures are those where cracks or fractures form through the material. This releases all the energy stored in the rocks in one go as seismic waves causing an earthquake.
Now this has been going on for millions of years so that there are already a large number of fractures or faults in the lithosphere. These pre-existing points of weakness are now the first part of the lithosphere to fail when stress builds up.
they move up against each other.. constantly moving and the pressure gets to be too much and boom an earthquake happens.. islands are made by being pushed upward. it is a fascinating topic to read up on more
The are both related to the movement of tectonic plates.
That causes earthquakes
it is at faults or cracks
Earthquakes
It all depends on how big the fault is, bigger ones will cause bigger earthquakes, while smaller, or small ones may cause no earthquake at all.
Earthquakes and volcanoes are most common near the faults at plate boundaries.
There is no relationship between tornadoes and earthquakes.
most people in calafornia are really fat and they move about wobbleing the tetonic plates.
Transform boundaries are seen in earthquakes that are caused by normal faults. Some types of faults are listric or ring faults.
Faults are the boundaries between tectonic plates and are not the cause of earthquakes. The motion of one plate against another or the subduction of one plate by another can eventually cause a slippage, and it is this slippage that causes earthquakes.
Yes!
it is the movement of plates between the surface of the earth!:0)
Faults DO NOT produce earthquakes, faults are produced by earthquakes. This means that earthquake loci are centered on and along faults. The energy released by an earthquake is the stress energy built up as a result of plate tectonic forces.

Faults
Faults can create cracks in the earth and cause earthquakes.
