(Name (Red IDThe Directorate of Public SafetySkull Island , Republic of Arba casing-tectonic SettingSkull Island is one of the islands situated in the Arba central office near the Hamsa Oceanic Trench . The presence of the naval trench indicates that Arba and Hamsa ar colliding or move towards each other . The place where the nautical trench nates be add together is the subduction zone or area wherein the continental case meets the marine house . The Arba dwelling being a continental plate , is less dense than the oceanic plate . Thus upon the secure of associated with subduction , the oceanic plate is pulled towards the mantle under the continental plate . The stress associated with this phenomenon is a compressional stress which produces reverse fault . The boundaries of Hamsa Plate and Talata Plate are characteriz ed by a series of mid-ocean ridges .
This illustrates that b stray Hamsa Plate is locomote northwards converging with Arba Plate , it is moving away from the Talata Plate . This represents an underlying convection current in the understructure s mantle . The forces below the earth s crust starts to drag the ii plate s apart making way for some magma to verbalize off into the surface creating new crust . This process is cognise as seafloor spreading . The ridges are not in a straight line , which means that some parts of the plates are slue sideways . A shear stress is shown highlighted by the emplacement of the ridges . The plate boundary between Hamsa and Talata is called a m odify boundaryAs can be...If you want to get! a full essay, order it on our website:
