Earthquakes

Earthquakes be f on the whole outing almost everyday all everywhere the world. Most of the time seisms are not hearty teeming to be felt by people, but the shiver caused by an seism is recorded by a seismogram. These are fit(p) all over the world at different points. solely occasionally will a big magnitude earthquake strike and cause damage to the region. Around the world thither are some faults, depending where these faults are plays a major factor in determining where an earthquake will happen. It is these faults that are the causation for earthquakes. The type of fault will also determine how much an earthquake will happen. A mid-ocean ridge dos under(a) the sea at a different terminus ad quem. This is where 2 plates are been pulled apart because of tension. This so allows new oceanic rancour 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 adjourn motivation 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 spring of earthquakes at divergent boundaries. When the tension pulling apart the two plates becomes in like manner very much then the oceanic crust will fracture. This fracturing is caused by many normal faults happening as sh own 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 hold in a relatively short space of time, this is the...
