Earthquakes

Earthquakes are f altogether outing almost everyday all everywhere the world. Most of the time seisms are not rigid teeming to be felt by people, but the shiver caused by an quake is recorded by a seismogram. These are fit(p) all over the world at different points. only occasionally will a big magnitude earthquake strike and cause damage to the region. Around the world there are some faults, depending where these faults are plays a major component in determining where an earthquake will happen. It is these faults that are the fountain for earthquakes. The type of fault will also determine how very much an earthquake will happen. A mid-ocean ridge dos to a lower place the sea at a different border. This is where ii plates are been pulled apart because of tension. This so allows new oceanic cheek 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 mark off unavoidableness vale at the divergent boundary. This crack like valley is caused by the tension pulling the plates apart, do ruler faulting to occur a number of times in the divergent boundary.

It is these normal faults that are the cause and therefore the rakehell of earthquakes at divergent boundaries. When the tension pulling apart the two plates becomes as well 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 be! cause the crust is been extended. When the tension becomes too much the faults slip vertically. They lean a large outdistance in a relatively short space of time, this is the... If you want to get a full-of-the-moon essay, order it on our website: OrderCustomPaper.com
