A Discussion On Earthquakes :: essays research papers

A Discussion On Earthquakes perchance Mother Nature offers no greater force than that of the earthquake.Across the match of time, earthquakes have been recorded for their incredibledestructive forces, and their abilities to awe mankind with their unusualforce. Earthquakes domiciliate often strike without any notice, leveling large citiesand cleaning scores of innocent people. Not only can earthquakes bring ill-use tosociety through these methods of destruction, but they can also cause millionsof dollars expense of damage to the areas they destroy, causing economic chaos.An earthquake is a natural phenomenon, occurring throughout the history of theworld. Descriptions as old as recorded history prove the significant effectsearthquakes have had on peoples lives. Long before there were scientifictheories for the cause of earthquakes, people around the world created folkloreto explain them. Until new-fangled times, science has not had a completeunderstanding of how earthquakes are caused, and what can be d angiotensin-converting enzyme to predictwhen they will strike. This essay will address how earthquakes are formed andoccur, how scientists can more accurately predict the stretch of earthquakes.Before contemplating how earthquakes might possibly be prevented, it isessential that the process and administration of and earthquake be understood.Earthquakes are caused when the earths in incrustationational plates incite, rub, or pushagainst each other. The earths crust (the outer layer of the earth) is made upof seven major plates and more or less thirteen smaller ones. The name plateis used to describe these portions of the earths crust because they areliterally plates or sections, composed of dirt and rock. These plates floaton molten lava, called magma. Since the plates are floating on magma, they canslowly escape. The fix where friction occurs between plates is called a fault.A fault is a jibe in a plate or a place where deuce or more plates ca tch. Anexample of a fault where two plates meet is the San Andreas fault in California,where the Pacific and North American plates meet. The plates are nigh 30miles thick under land and can be one to five miles thick beneath the ocean.The plates move because of convection currents. Magma has currents like theocean does, that move in a circular motion beneath the plates. When two platesare pushing against each other, they are constantly building up latent hostility on thefault. When two plates finally slip, they release a great get along of energy inthe form of shock waves. These shock waves cause vibrations, which in turncause the ground around the fault line to move and shake.
