WebSubduction allows water from the subducting plate to be driven upward, off the subducting plate and into the mantle wedge. This lowers the melting point of the mantle, and it melts to form magma. This magma will rise and leak into the crust forming a volcano. This process can create a chain of volcanic islands.

WebA slab can directly drag a plate toward the subduction zone if it is joined to a plate. On the other hand, a slab that is not securely fastened to a plate cannot pull directly on the plate. Instead, when it sinks, it creates mantle circulation patterns that act as a kind of suction effect, dragging neighboring plates toward the subduction zone ...

WebPyroclastic flows are hot density currents of pumice, ash, blocks, and volcanic gas that rapidly move down the slopes of a volcano. They may be initiated by collapse of eruptive columns, by explosive eruptions that boil over, and by the collapse of lava domes. Pyroclastic flow deposits are important components of most composite volcanoes. WebSep 15, 2014 · Understanding plate motions. By Subduction Zone Science. Scientists now have a fairly good understanding of how the plates move and how such movements relate to earthquake activity. Most movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident. September 15, 2014. WebThe subduction process causes bending of the down going plate, creating a deep trench. Continuing movement on the subduction zone associated with the Japan Trench is one of the main causes of tsunamis and earthquakes … dutchmann porsche youtube
