Juan De Fuca Plate
The Juan De Fuca tectonic plate is found on the west coast of North America. It is next to the North American plate, and according to America’s Tectonics, the Juan de Fuca plate is getting subducted under it. This plate is made of oceanic crust, but it is also basaltic in some areas. It was named after the pilot and sailor, Juan de Fuca, an explorer from Europe in the 1600s. The Juan de Fuca plate has a divergent boundary in the Juan de Fuca ridge. New material is made by the Juan de Fuca ridge constantly, which is volcanically active. The Juan De Fuca plate used to be a part of a larger plate called the ‘Farallon’ plate. The Farallon plate broke apart 200 million years ago and resulted in the formation of the Juan de Fuca plate

    Tectonic plate’s movement creates ocean basins, mid-ocean ridges, through collision. Colliding plates push sedimentary materials into an uplifted mass of rock that contains numerous folds and faults. The Earth has undergone a number of mountain building periods. The process of creation is first by the accumulation of sediments then the tectonic collision causes rock deformation and crystal uplift and finally the isocratic rebound continues to cause uplift despite erosion and causes the development of new mountain peaks through block faulting.…

    The earth’s crust is made out of plate tectonics. Each plate has a defined boundary and direction it moves. The plates in Earth’s crust perform two actions; they submerge under each other or they spread out. The Pacific Plate is the largest plate and it borders around many plates. The Pacific Plate moves northwest. New crust is formed from magma outpours, which are a result of the zones spreading. The tectonic plates created the islands. When the tectonic plates move, it creates the change in geography. Active volcanoes together shape the way islands are build. The magma from the volcano and the deposits from the plate are needed to create the pacific islands structure. The buildup of deposits eventually pushes pass sea level to create the island. The islands that are part of the same volcanic chain will all take over a millions years to rise.…

    At a hotspot, the underlying mantle is hotter than average causing ‘mantle plumes’ to rise to the bottom of the lithosphere, find a thin or weak part of the lithosphere, and breaks through. In the case of the Hawaiian islands, the hotspot is underneath an oceanic plate and the lava has built up until it is higher than the surface of the sea. These hotspots remain in the same place in relation to the mantle, but the plates move across the hotspots. The Pacific plate has moved across a hotspot in the ocean leaving the chain of Hawaiian Islands which have been formed at different times over millions of years. By dating the rocks which make up the Hawaiian Islands, it is clear that the tectonic plate must be moving in relation to the hotspot- a key piece of volcanic evidence.…

    The reason for this is because of the buckling and stress from the movement of the tectonic plates. The epicenter of the earthquake was 60 meters below the ocean floor about 100 miles off the coast of Chile. Valdivia and Puerto Montt suffered significant damages based on how nearby they were to the center of a massive quake (extreme). The earthquake was a megathrust earthquake which is caused by the release of mechanical stress between the subducting Nazca Plate and the South American Plate which is on the Peru-Chile…

    Denali Fault

    This specific plate has brought up ocean floor, and pieces of continents northward to form accretionary terranes. Most of this terrane are known as groups of rocks that are surrounded by faults, different types of fossils, and other types of physical properties. Due to the Pacific Plate subducting beneath the North American plate, it creates the Denali fault system. Denali consists of a right lateral strike-slip fault over 720 miles long (Sharpe). This strike-slip fault is a part of the larger fault system which includes the San Andreas Fault system in…

    With continued subduction and convergence, volcanic islands collided with North America and those rocks were thrust up on the continental margin. Deformation, metamorphism and magmatism accompanied this collision and gave rise to the Taconic Orogeny. Rocks metamorphosed and deformed in this event are seen in the Blue Ridge and Piedmont provinces. This…
