Plate Boundaries and Earth waving Featurs - Essay ExampleThis analysis seeks to explain and help comprehend diverging zones. A boundary with divergence is a location where plates move apart while occurring above the growth convection currents. These currents rising push upon the base of the lithosphere, forcing it up while flowing beneath it. This tangential surge results in a drag of the plate substance over it, in a similar direction flow. At the apex of fortify, the overlying plate gets elongated thin, and because it cannot hold on anymore, it fractures and tows apart. Divergence occurs when the boundary plates move with divergent velocities both vertically and horizontally. According to Stricklers 2nd law of GeoFanstasy, divergence occurs due to a gigantic stress at a tremendously slow rate on the boundary plates. The up and good deal movements result in distortion of the earths crusts resulting in fractures and joints, breaks and slips and folds. Krafla Volcano the northern part of Iceland clearly shows the consequences of these plate movements. At the Krafla Volcano region, the current ground fractures continually widens as new ones emerge after(prenominal) a few months. In the period between 1975 and 1984, a number of rifting activities took place close to Krafla gap region. A few of the rifting incidents were pursued by some significant volcanic activities the ground gradually bloom 1-2 meters prior to unexpected dropping, which signaled a looming eruption. In the era linking 1975 and 1984, the ground rose by a stun 7 meters due to the plate divergence (Condie, 1997). The movement of the earths crust results in different formations. The conditions bringing forrad these differences include the Temperature, Type and magnitude of the force and Rock subject. Economic resources consist of naturally occurring materials of earth in dire demand for different uses. These economic resources include minerals, rocks and gases. Nature and divisions of th ese resources relate to geological structure and its explanation resulting in a wealthy economic resource. S shed light on 2 Haiti an earth reel feature location accession An earthquake feature point is a place where there is a high activity underpass resulting to frequent earthquakes and other tremors. Maps of Japan Map of Japan showing the three plates in contact The type of earthquake Megathrust A Megathrust fault is a boundary connecting a sub-ducting zone and an overriding plate. A Megathrust quake results from an abrupt slip between the two plates trim back the fault line. It occurs in an area of Megathrust fault. An earthquake results from friction of plates and is increases as it progresses from one layer to another. Grinding of plates against the other is the main cause of earthquakes (Rafferty, 2011). Japan sits at the top of three continental plates ripbing against the other the Pacific, the Eurasian and the Philippine Sea plates. These three plates continually rub against the other developing a tremendous pressure escaping with a vicious force. According to the Stille (2006), Japan is in a ring of fire, it experiences an earthquake every seven minutes. A seismic network takes down the measurements of the earthquake while a seismograph measures the magnitude or energy released while intensity is the strength the quake shakes things. The quakes produce two waves P waves, a compressional wave and S or shear wave. The shear wave is slow
