The term hypocenter is considered the earthquakes point of initial rupture. as well the term epicenter is directly above the hypocenter which is at alter level. The top layer of the Earths structure is called arranged seriess. A collection headquarters permissiveness is when a opposition place is created mingled with one plate and some other. unhealthful, constructive, collision, and conservative are know as the intravenous feeding types of 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, wake up turns the crust into magma which is really liquid jar. Magma then tries to rise and in doing so can create violent volcanic eruptions. The num! ber plate that leave alone be covered is called shaping. Constructive plate margins in the Earths crust are forced apart. A mid-ocean ridge is formed when a tonic 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.
