Earthquakes

Earthquakes are fall outing almost everyday all everywhere the world. Most of the time seisms are not strong teeming to be felt by people, but the shaking caused by an earthquake is recorded by a seismogram. These are fit(p) all over the world at different points. totally occasionally will a larger magnitude earthquake strike and cause damage to the region. Around the world thither are some faults, depending where these faults are plays a major divisor in determining where an earthquake will happen. It is these faults that are the causality for earthquakes. The type of fault will also determine how practically an earthquake will happen.

A mid-ocean ridge dos under the sea at a different boundary. This is where two plates are been pulled apart because of tension. This so allows new oceanic crust to be made in the divergent boundary, as magma rises and eventually sets on the sea floor.

If the plates on either side of the divergent boundary continue to deal then the ocean slowly becomes larger in width, a process called seafloor spreading. Mid-ocean ridges are characterised by a crack want vale at the divergent boundary. This crack like valley is caused by the tension pulling the plates apart, causing ruler faulting to occur a number of times in the divergent boundary.

It is these normal faults that are the cause and therefore the origin of earthquakes at divergent boundaries. When the tension pulling apart the two plates becomes too very much then the oceanic crust will fracture. This fracturing is caused by many normal faults happening as shown in the diagram. The normal faults happen because the crust is been extended. When the tension becomes too much the faults slip vertically. They lean a large distance in a relatively short space of time, this is the...
