The Magnicent Earth's Surface

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

II: Plate tectonics shows the features and movement of the Earth. The theory of plate tectonics says that the outer shell of the earth is broken down into pieces often called plates (Korenaga). These plates hover over the mantle creating movement (Marshak). With plate tectonics you can determine the earth’s features without actually seeing it.

Often the two become confused: lives and human tragedy are considered a product, something that will engender interest and thereby generate revenue. The greater the suffering, the more successful the program and the greater market share.

“The crust of the earth is a vast museum” is very important in chapter 8. This quote is taken from The Origin of Species. This quote is a metaphor comparing the all the animals on the earth microscopic species to Elephants, and having them in the spacious museum. Darwin is saying that how many creatures we find small or big there will always be more out there. This quote is pretty explanatory and not difficult to comprehend.

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 crust is the outer most portion of the earth and takes up less than 1% than the total volume of the earth. It is commonly compared to the skin of an apple, whereas the apple represents the earth. The temperature of the crust varies from the air on top, to upward of 1600 at the deepest parts. The tectonic plates are part of the crust of the earth, moving and shifting on the softer mantle or

Tectonic activity varies due to geographical location and position of tectonic plate boundaries. The Earth's crust is made up of continental and oceanic plates, which move across the surface of the planet, meeting at plate boundaries. Plate tectonics cause volcanic activity, tsunamis and

The crust is the outermost layer on the planet, Earth. According to geologist studies, four point four billion years ago the formation of Earth's crust developed. The crust, also known as the top layer, is the outermost layer of the planet. This is one of the four layers that make up the structure of Earth. The requirements of the top layer is to interact with the mantle to be a part of the geosphere. The crust itself is made of three main types, has two types of crust, and is split into parts.

The earth is a massive sphere composed of different layers. The layers above the surface are gas, the surface is liquid and solid, but deep below it’s a dense liquid that moves around. The liquids inside the earth move because as the center is heated the material in it is hot and so its density is reduced. Materials with a lower density tend to rise up as materials with higher densities lower, this causes all the materials inside of the earth to

It has been known for well over a century now that the Earth’s core, mantle and the crust make up the basic structure of the Earth. However, there is some controversy over how and when the Earth produced its core, mantle and crust. In this essay, I will first discuss about the formation of the Early Earth and its Moon, then about the methods used to pinpoint the age of the Earth. Other than that, I will also expand on core and mantle formation, as well as the eventual production of the continental crust.

Although convection current in the earth layer are closely associated with the movements of the tectonic plates they also play a role in the formation of rocks, such as the igneous and metamorphic rocks. Igneous rocks form through the solidification of magma or lava. This can occur in two different places, on earth surface and under earth surface. Rocks that form on earth surface are called extrusive, rocks that form under earth's surface are intrusive plutonic rocks. A Metamorphic rock is formed when the protolithic rock is exposed to heat and pressure.There are also two different type of metamorphic rocks contact and regional metamorphic rocks.

We learned that in 4th grade. We went more in depth with that this year. There are two types of Crust; oceanic and continental. Oceanic is thinner and is mostly made of out basalt. Continental crust is mostly made out of granite. This layer drifts slowly and is solid. The Earth has sub-layers. The lithosphere is part of the crust and uppermost Mantle. Next down is the Asthenosphere, where all the tectonic plates are. Then the lowest part of the Mantle is called the Mesosphere. The Mantle is semi-solid and has convection currents that move the tectonic plates. It contains more iron than the layer above. The outer core has convection currents that create the magnetic field. It’s the swirly hot iron that really causes it. This is the only layer that is liquid. The inner core is solid because of the great pressure on it. It is extremely hot. The deeper you go the hotter it gets and iron increases. Two out of the four main layers have convection

The rock cycle is the process where rock changes over time. It doesn’t have a beginning or end. There are three types of rocks, sedimentary, igneous, and metamorphic rocks. Sedimentary rocks form when water, like rivers and oceans, carry away broken down rocks. When the rock fragments settle down on the bottom, they compact and cement together, by their own weight, forming sedimentary rocks. As the plates move they bring the rocks under the earth. While sedimentary rocks are below the earth’s surface, the extreme heat and pressure crush and change the rocks, which are called metamorphic rocks. The extreme heat then melts the metamorphic rocks into magma. When the magma cools it turns into igneous rock. There are two types of igneous rocks,

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

Earth is made up of five major layers including the inner core, outer core, mantle, upper mantle and crust. The upper mantle of the Earth is a approximately 1100C, a temperature so hot that the rock melts to form a molten layer, causing the pieces of the Earth’s
