Plate Tectonics have been changing the world from the beginning. There are three things that make up the earths crust that helps the plate tectonics work. The first are the core, mantle, and the crust. Second is the ring of fire, which is a major plate movement area. Last there are the forces that the moving plates form like earthquakes and volcanic eruptions. The earth’s layers, Ring of Fire, and the natural cause of plate tectonics are what change our world everyday.
The Core is the center of the world also the hottest part of the earth because it is made up of molten rock. The Mantle is the middle of the three layers of the earth and the mantle is made up of semi solid hot rock. The last layer of the earth is the crust. The crust is made up of a rocky shell. This shell is what absorbs nutrients and where we grow our crops. The core, mantle, and the crust all work together to fill in the land that is cracked and moved while the plated work to change the Earth. What happens is when the plates move and crack the earths layers the core will surge the molten rock up into the crack or place that is open and fill the hole where the molten rock will cool and harden into new mantle and crust. The core also recycles the material that had broken during the faulting and turns it into new core. This process mostly happens

The Ring of Fire is located in the Pacific Ocean and is in a semi circle shape. The Ring of Fire produces about 90% of all the earthquakes that happen. The Ring of Fire interacts with plate tectonics because it is a area where several plates converge on each other making faults and earthquakes. The Ring of Fire affects many areas the main one being Japan. Since the Ring of Fire makes so many earthquakes and because they are so big it creates large tsunamis that destroy many cities and towns when they hit. Overall plate tectonics are widely affected by the Ring of
The Mantle makes up 70% of the Earth’s mass and is mostly solid but capable of flow, causing changes in the Earth’s surface.
Fires are devestating but also have some positive features. Shifting plates may makes fossil fuels such as petroleum and natural gas easier to access by burning off the old layers. FIres cause renewal and change.
Earthquakes are a natural part of the Earth’s evolution. Scientific evidence leads many geologists to believe that all of the land on Earth was at one point in time connected. Because of plate tectonic movements or earthquakes, continental drift occurred separating the one massive piece of land in to the seven major continents today. Further evidence supports this theory, starting with the Mid-Atlantic ridge, a large mass of plate tectonics, which are increasing the size of the Atlantic Ocean while shrinking the Pacific. Some scientists believe that the major plate moveme...
The interior structure of Earth is chemically divided into an outer solid crust, the mantle, a liquid outer core, and a solid inner core. The core is largely composed of iron, along with nickel and silicon. Other lighter elements are usually in the crust.
Earthquakes are caused by tectonic plates moving in the earth's crust. They either move apart or pull together at faults. Two forms of faults are normal faulting where the hanging wall moves downward causing rocks to be pulled apart by tension and reverse faulting, which is the opposite where the hanging wall moves upward casuing rocks to be forced together by tension. These movements cause tectonic plate boundaries called divergent boundaries, convergent boundaries and transform boundaries. Each boundary is different and play a
The earth has four major layers: the inner core, outer core, mantle, and crust. The crust and the top of the mantle make up a thin skin on the surface of our planet. This skin isn’t all in one piece. It is made up of several pieces covering the surface of the earth, like a puzzle. These puzzle pieces keep slowly moving around, sliding past one another and bumping into each other. We call these puzzle pieces tectonic plates. The edges of tectonic plates are called plate boundaries. Plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. The edges of the plates are rough and get stuck while the rest of the plate keeps moving. Eventually the plate edges of a fault unstick and results in an earthquake.
Now, to really be able to contrast plate tectonic theories, you need to understand that the earth is made up of layers.
Before examining the Northridge event, understanding the naturally occurring hazard that is an earthquake will help to better understand exactly what happened and why it was such an important geological event. With four distinct layers, two layers, the crust and upper portion of the mantle, compose the skin that is the surface layer of the Earth. The crust is not a single, continuous piece. It is actually several different pieces, or plates, that come together to form the puzzle that comprises the surface of the Earth. These plates are in constant motion rubbing against one another. These areas, known as fault lines, where the plates rub up against one another have spots where one plate ”gets stuck while the rest of the plate keeps moving. When the plate has moved far enough, the edges unstick and is how most of the earthquakes around the world occur” (Wald, 2012). The energy stored from the friction of the two plate...
Plate tectonics is a unifying theory that the earth’s crust is divided into over dozen plates that float over the mantle; a layer between the crust and the outer core, that represents about 85% of the total
First you might need to know definition of tectonics. It is a theory in geology. The lithosphere of the Earth is divided into a small number of plates which float on and travel independently over the mantle and much of the Earth’s seismic activity occurs at the boundaries of these plates. That is the official definition of Plate tectonics. secondly, this plate covers many parts of continents. plate boundaries don’t go according to Continents boundaries, they make their own boundaries. The North American plat...
The Pacific plate is moving northwest in relation to the North American plate, and it is believed that the total displacement along the fault since its formation more than 30 million years ago has been about 350 mi. Movement along the fault causes earthquakes; several thousand occur annually
The interior structure of the earth is made up of crust, the mantle and core (inner core and outer core). Earthquakes occur on the crust. Crust forms the external layer of the earth surface. On the crust, the plate tectonics forces are in charge of causing the abrupt earth movements. Due to the existence of an immense temperature and concurrent pressure difference in the outer layer and inner layer of the earth, convection currents occur at the mantle. This energy results from overwhelming decomposition of radioactive substances contained by the rocks found at the interior of the earth. The developed convection currents lead to movement of lava; cold lava finds its way to the interior of the earth crust, while the molten lava which is generally hot, leaves the interior of the earth to the outside of the earth crust. These kinds of circulations occur at different locations of the earth surface and consequently results in segmentation of the earth due to movement in different directions.
They are the earth’s crust; they move very slowly every year. As the tectonic plates slide over each other they cause earthquakes. Earthquakes produce various damaging effects this includes damage to structures of buildings, bridges and other standing formations which then...
Convergent boundaries, divergent boundaries and convection currents all examples of physical evidence that supports the theory of plate tectonics. Continental drift is the theory contrived by Alfred Wegener in 1912 that states that Earth’s tectonic plates are in slow constant movement. At the time he didn’t know how the continents moved. The theory was soon modernized in the 50’s and the theory of plate tectonics became was born. Plate tectonics is the theory that tectonic plates are in slow constant movement due to convection currents in the mantle. Now we know for sure, thanks to scientific studies of convergent boundaries, divergent boundaries, and convection currents in the Earth’s mantle, that the continental drift and plate tectonics theories are not
