How Does Metamorphic Rocks Play A Role In The Formation Of The Earth

As a tectonic plate slides into the mantle, the heat releases fluids trapped in the plate. Seawater and carbon dioxide, rise into the upper plate and can partially melt the overlying crust, forming magma. And magma most likely means volcanoes are around.

Tectonic plates are powered by convection currents, which is the circular movement of magma within the mantle. These currents are powered by the core, which heats the magma, causing it to rise, cool and fall back down. This circular motion causes the plates, which float on the mantle, to

Volcanoes can be found throughout the entire world and are formed when there is a rupture in the mantle of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water.

The Earth’s outer crust is made up many tectonic plates that move over the surface of the planet. When the plates come collide, volcanoes will form sometime (National Ocean Service). Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a “hot spot” (National Ocean Service). A hot spot is a plume of magma or molten rock that rises from within the Earth then reaches the surface forming underwater volcanoes which may grow tall enough to

Convection currents may bring magma to the surface at diverging boundaries. Sedimentary rocks from the ocean floor gets pushed down to the mantle at convergent boundaries. The crust soon melts and rises to the surface creating igneous rock. Typically mountain ranges are metamorphic rock, maybe our mountains are.

Initially, earthquakes shape the Earth’s surface by creating mountains and geysers. In the article “Historic Earthquakes,” it reads, “High intensities were observed in the northwest section of Yellowstone National Park. Here, new geysers erupted, and massive slumping caused large cracks in the ground from which steam emitted” (Stover 3). Consequently, when the geo-process of earthquakes occurs, it molds and changes the earth by creating new geothermal

Some rock’s in the Earth’s interior that are solid, are so hot that, if the pressure on these were released, or they are convected into a lower pressure zone, they could begin to melt

Metamorphic rocks are the result of the transformation of a pre-existing rock type, the protolith, in a process called metamorphism, which means "change in

The solid part of the Earth consist of solid rocks and soil. The Earths surface is the geosphere. The hydrosphere makes up all of the water on Earth's surface. The Earth is divided into three layers the crust, mantle, and the core. The crust is very brittle and this is why it was easy for Mount St. Helen to blow it to pieces. Tectonic plates are what glides underneath the underlying asthenosphere. This is what causes mountains to shift or grow. This can affect when volcanoes erupt. Volcanos are located near tectonic plate boundaries, where plates either collide or separate.

The rock cycle explains the relations between the three different types of rock. Any of the igneous, sedimentary, and metamorphic rocks can melt into magma and cool into igneous rocks. When particles from the former rocks compact and cement together, sedimentary rocks are formed. Rocks that are exposed to high temperatures and pressures can be changed physically or chemically to form a different rock, they are called metamorphic

Metamorphic rocks change based upon heat, pressure, and chemical processes. Sedimentary rocks change into metamorphic rocks by withstanding heat, pressure, or by chemical action. Igneous rocks change by weathering and erosion. Metamorphic rocks can change into igneous rocks by experiencing melting and cooling. Sedimentary rocks change by weathering and erosion. Sedimentary rocks are formed by the accumulation of sediments and other fragments. When utilizing the rock cycle igneous rocks can change into both sedimentary rocks and metamorphic rocks when experiencing weathering and erosion. Igneous rocks are formed from the volcanic magma that cools and hardens on the surface of the earth.

Frictional melting has caused scientist to be puzzled in how they formed considering that the rock was somewhat molten and exhibits characteristics of formations that are under low heat and high pressure. In the upper crust, frictional melting can be seen along in different environments. In some scenarios, it can be visible in areas that prehistoric glaciers were present, and its aftermath of being around higher

An eruption of a volcano is one phenomenon that occurs in nature. Deep within the Earth, it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Because it is lighter than the rock around it, magma rises and collects in magma chambers. Eventually some of the magma pushes through vents and fissures in the Earth 's surface. This is how a volcanic eruption occurs. Magma that has erupted is called lava.

The plates in our planets surface move on account of the serious warmth in the Earth's center. This causes liquid rock in the mantle layer to move. It moves in a way called a convection cell that structures when warm material ascents, cools, and finally sink down. As the chilled material sinks off, it is warmed and rises once

The initial rocks are very ultramafic and as time goes on they became more felsic. The magma during the formation of the ultramafic to mafic rocks the magma becomes more felsic until these rocks stop forming. This is because compatible elements were crystallizing into minerals. These minerals then made up rocks after each step finished. Slowly the minerals and rocks formed became more felsic and the melt became less felsic. It will continue to get less felsic until all the magma has crystallized. For example, we went from Dunite (step1) all the way to Granodiorite(step ten). Dunite was very ultramafic while Granodiorite was more felsic since it had more silica in it. The last melt could have formed a Quartzolite or a Quartz-rich Granitoid depending on how much silica, alkaline feldspars, and plagioclase was left. Silica was the most abundant element in the melt so therefore the percentage of it in the melt remained high even after a decent amount of it had been removed. For example, at the end of step six there was still 125 silica atoms left in the melt. The steps that created ultramafic rocks were steps one through six since they had olivine, plagioclase, and pyroxenes in them. The mafic rocks were created in steps seven and eight since they had no olivine or felsic minerals in them, but still had pyroxene and plagioclase in them. The steps nine and ten created felsic rocks since they had felsic minerals (quartz and Alkali feldspars) as well as the mafic minerals in
