In most cases the term earthquake is used to ready any(prenominal) seismic event. There are other causes that help in creating earthquakes. Vol merchant shipic activity, mine blasts, nuclear experiments as well as rupture of geological faults. The term hypocenter is considered the earthquakes point of initial rupture. similarly the term epicenter is directly above the hypocenter which is at smear level. The top layer of the Earths structure is called coherent seriess. A collection home base permissiveness is when a showdown place is created mingled with one plate and some other. evil, constructive, collision, and conservative are cognize as the 4 types of plate margins. An earthquake has the ability to polish at all four of the types of plates while a vent-hole can be located amongst two types of plate margins. The four plate margins are described as follows; The first plate that testament be described is the Destructive plate margins. Destructive margin plate consists of oceanic plates moving toward one another and disappearing into the mantle. This would be considered the subduction zone.

Violent earthquakes are the result of descending(prenominal) attract that creates increased pressure at the margins. Because of the friction that is caused, incite turns the crust into magma which is really liquid careen. Magma then tries to rise and in doing so can create violent volcanic er uptions. The blurb plate that leave alone! be covered is called inferential. Constructive plate margins in the Earths crust are forced apart. A mid-ocean ridge is formed when a mod oceanic crust is created due to the magma rising and solidifying. Igneous rock is what the ridge is make of and it can be found usually on the sea bed which is below sea level. sometimes there is an exclusion, and that exception would be found in Iceland. The third plate that will be described Collision plate...If you fatality to get a full essay, order it on our website: OrderCustomPaper.com
