What crust is the Eurasian Plate made of? What tectonic plate is primarily comprised of seafloor crust? How many layers are in the Earth's crust? What is the oceanic crust always doing? What type of rock is foun
Crust: Earth's outermost layer comprises two distinct types: continental and oceanic crust. Continental crust, rich in silica, is an average of 44 miles (70 kilometers) thick. In contrast, oceanic crust predominantly consists of silica-poor rocks like basalt, making it thinner and more flexible...
Mid-ocean ridges are higher than surrounding oceanic crust primarily because of what? What type of boundary causes folding? What type of boundary is the North American Plate? What is it called when two tectonic plates meet? What type of plate boundary is the Aleutian Trench? What are the typ...
What are the best natural analogues for former subducted oceanic crust?Not Availabledoi:10.1016/j.gca.2006.06.1309ZackT.Elsevier LtdGeochimica Et Cosmochimica Acta
Eclogite:Can be brought up through orogenic (mountain-building) processes where subducted oceanic crust is pushed into the mantle, then later exhumed or brought up by tectonic uplift. Peridotite:Sometimes reaches the surface through processes like serpentinization (hydration of olivine into serpentine) ...
How is granite formed Granite formed in a number of different situations. Some granite was generated in zones of rifted continental or oceanic crust, but most granite was generated in zones of collision between continents and oceanic crust, and where continents were amalgamated. ...
Inter-Oceanic Hotspot Volcanoes Inter-oceanic hotspots form under oceanic plates. The magma that is formed in these magma chambers is basaltic in nature, having a low viscosity and low water content. This type of magma primarily produces very fluid lava flows. Pressure does not tend to build up...
Igneous rock is produced by the melting of the Earth's crust into magma. There are two primary types of igneous rock: intrusive and extrusive. Intrusive igneous rock is produced by the slow cooling of magma below the surface. Extrusive igneous rock is produced by the rapid cooling of lava ...
Layers of the Earth: The Earth consists of several layers that sit on top of one another. The outermost layer is the lithosphere, and this layer is made from tectonic plates. Answer and Explanation:1 The lithosphere is broken into several tectonic plates that are composed of hard rocks. This...
A tectonic plate is a boundary or region that can be specified as a division of soil or crust on the Earth's lithosphere. A tectonic plate can be a continental or oceanic plate: The continental plate is a crust mostly compose of granite, while the oceanic plate is an oceanic crust which...
