Four Layers Of The Earth Research Paper

There are three main layers on the Earth. The first is, the crust, the outer layer of Earth. It’s everywhere, on dry land and the ocean floor, however it’s

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.

Cenozoic sedimentary rocks predominated to the west and east of the central mountain while plutonic rocks predominated in the peninsular ranges. The irregular contact between these geologic regions reflects the ancient topography of the area. The ancient oceanic crustal plate created an archipelago of a volcanic island. The former's subduction created immense volumes of magma. This resulted to the congealation of plutonic rock in the crust. The local rocks that existed before the tectonic forces uplifted, and erosion capped the deeply buried plutonic rocks that formed a steep and rugged mountains coastline, similar to that present one, which in the west coast of south America.

The lithosphere is defined as the rigid outer part of the earth, consisting of the crust and the upper mantle; it is the solid, out part of earth. The picture

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.

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 Grand Canyon’s display of layered rocks is magnificent and immense. The Canyon has many types of rocks including metamorphic, igneous and sedimentary. 2 billion years ago, igneous and metamorphic rocks formed in the inner gorge of the Grand Canyon. On top of these rocks sedimentary rock layers were created. Over time these layers of rocks transformed with erosion, tectonic actions, intrusions, and uncomformities.

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

The different tectonic plates rest on the mantle, a very hot layer of earth that is directly beneath the crust. There are seven major tectonic plates, their names are The Pacific Plate, The North American Plate, The Eurasian Plate, The African Plate, The Antarctic Plate, The Australian Plate, and The South American Plate. In addition to these major plates there are also many smaller tectonic plates that make up parts of the Earth's crust. When the boundaries between plates shift, this causes earthquakes. There are three types of movements that cause earthquakes. Divergent is when the plates move away from each other, Subduction is when one plate moves underneath another, and Transform is when the plates grind against each other. The lithosphere is another name for earth's crust and mantle, it is made up of all the tectonic

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.

The rock cycle is a very important cycle of our lives, we can change our form from any three ways. There are three types of rocks we can change into, metamorphic, igneous, and sedimentary. Changing our form isn’t the easiest thing in the world. We must change by either melting, erosion and compression, or heat and pressure.

Earth is in fact an intricate planet that has multiple layers of differing compositions. To be exact the earth has four main layers. The uppermost layer is the one humans come in most contact with, the crust. The crust consists of “thin silicate rock material”(Structure of the). Although the crust is not entirely the same. Actually there are two distinct types of crust, oceanic and continental. “The continental crust is made up of mostly rocks similar to granite while the oceanic crust is much denser and made up of a material similar to basalt”(Structure of the, Rose). The second layer is called the mantle. “The mantle is much denser than the crust and contains similar to the crust mostly solid silicate crust”(Structure of the). “As we travel further down the earth we wind up in the outer core. The outer core is a core of molten nickel and iron. Finally there’s the inner core. The inner is a solid metal core made up of nickel and iron”(Structure of the). All these layers functioning together cast out a magnetic

     Metamorphic rocks are pre-existing rocks that are changed by heat and pressure. The pre-existing rock is called the parent rock, or protolith. Metamorphism occurs in these rocks when the minerals become instable. There are two types of metamorphism, contact and regional. Contact is high temperature, low pressure. It is basically a massive rock that is baked. Regional is high pressure and low temperature. Strong fabric, or layering, develops from

The continental crust consists of igneous and sedimentary rocks. The oceanic crust consists of the same with a substantial layer of sediments above the rock. The crust covers the outer ridged layer of the earth called the lithosphere. The lithosphere is divided into seven main continental plates. These continental plates are constantly moving on a viscous base.
