Plate Tectonics, And The World

The theory of plate tectonics states that the Earth’s lithosphere (top layer of the Earth’s crust) is split up into rigid sections called plates that are moving relative to one another as they move on top of the underlying semi-molten mantle. These plates are either continental, The North American Plate, or oceanic, The Nazca Plate.

There are many ways that Plate tectonics, earthquakes, and volcanoes are connected. The most reasonable way is the movements of the Earth 's crust. There are also many other plate tectonic related theories and studies that are connected with the earthquakes and volcanoes too.

The theory of plate tectonics states that Earth’s outer shell is divided into plates. The crust and upper mantle is broken into plates that move around on the mantle, changing in size throughout time. The lithosphere makes up the crust and upper mantle and the asthenosphere a plastic like layer beneath the lithosphere. There are three types of plate boundaries. Divergent boundaries where two plates move away from each other. The ocean widens and new crust forms at the mid-oceanic ridge. Convergent boundaries has three types of converging, moving two plates towards each other. First we have an ocean floor plate that collides with a less dense continental plate. Next an ocean floor plate collides with another ocean floor plate. Finally a continental plate collides with another continental plate. Transform boundaries were two plates slide past one another. The resulting effects of plate tectonics is landforms such as rift valleys,

First of all, the Earth was made billions of years ago. It all started in this way, asteroids, comets, planets, and moons were created. Earth’s rocky core formed first with heaty elements colliding and binding together. The flow of the mantle beneath the crust causes plate tectonics, the movement of the large plates of rocks on the surface of the earth.

Plate tectonics is the scientific theory that attempts to explain the movements of the Earth's lithosphere that have formed the landscape features we see across the globe today” (Briney). Geology defines “plate” as a large slab of solid rock, and “tectonics” is part of the Greek root word for “to build.” Together the words define how the Earth’s surface is built up of moving plates. The theory of plate tectonics dictates that individual plates, broken down into large and small sections of rock, form Earth’s lithosphere. These fragmented bodies of rock move along each other atop the Earth’s liquid lower mantle to create the plate boundaries that have shaped Earth’s landscape. Plate tectonics originated from meteorologist Alfred Wegener’s theory, developed in the early 20th century. In 1912, he realized that the east coast of South America and the west coast of Africa appeared to piece together like a jigsaw puzzle. He further examined the globe and deduced that all of Earth’s continents could somehow be assembled together and proposed the idea that the continents had once been linked in a single supercontinent called Pangaea. To explain today’s position of the continents, Wegener theorized that they began to drift apart approximately 300 million years ago. This theory

The three major types of tectonic plates are divergent, subduction and transform. Divergent plates tend to move apart from each other. Subduction plates are when oceanic plate moves under a continental plate. This can cause volcanos to erupt and large sized earthquakes. Transform plates slide back and forth against one another. The Lithosphere consists of the Earths crust and uppermost mantle. The North American plate and the South American plate are the major plates of the lithosphere. The lithosphere also consists of the Pacific plate, the African plate and the Eurasian plate. The Pacific plate is the only major plate that is mainly underwater and is also the largest plate in the lithosphere. The Earth was once one large continental body called Pangea, before the plates started

A German meteorologist and explorer Alfred Wegener put forth the theory of continental drift in the early 1900’s. Wegener pointed out that the earth’s continents looked as if they were all connected at one point in time. He also pointed out that some of earth’s features, including the long S-shaped mountain structure formed on the Atlantic seafloor, could fit snugly against the corresponding western seafloor of Europe and Africa (Sieh and LeVay 1998). Wegener proposed that all of the earth’s continents once formed one single landmass, which he named Pangaea or “all-land”. He concluded that Pangaea had broken up and separated due to the unidentifiable forces estimated 300 million years ago (Sieh and LeVay 1998). Geologists did not fully understand at the time that Earth’s continents could drift (Hazen 2012). After all, the continents do not float in the oceans. They are made from a solid material connecting to the mantle, a sphere of solid rock

The seven major tectonic plates comprise mostly on continental plates and the Pacific plate. The seven major plates from greatest to least are called: the Pacific Plate stretching 103,300,000 km2, North American Plate being 75,900,000 km2, Eurasian Plate being 67,800,000 km2, African Plate stretching 61,300,000 km2, Antarctic Plate being 60,900,000 km2, Australian Plate being 47,000,000 km2, and the South American Plate being 43,600,000 km2. With different tectonic plates, there are different ways they can move: divergent, convergent, and transform. Divergent plate movement is when both plates moving away from each other, creating a canyon that has magma pushing out from the bottom, forming new ground. Convergent is usually an oceanic plate and a continental plate are moving into one another, causing the oceanic plate to subducts into the mantle. This causes move active volcanos and earthquakes. Even though all of the plates are in the lithosphere, it's only the where Earth is flexible enough to move rather than flow. The lithosphere flexes when loads of weight are placed on it or

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

Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon. As the plates alternately jam and jump against each other, earthquakes rattle through a wide boundary zone. The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. The lithosphere is divided into 15 major tectonic plates: the North American, Caribbean, South American, Scotia, Antarctic, Eurasian, Arabian, African, Indian, Philippine, Australian, Pacific, Juan de Fuca, Cocos, and

Plate tectonics is a theory that the earths outer rigid layer, the lithosphere, is divided into plates that are constantly moving across the earths surface, much like ice does on the surface of a lake. When the plates pull away from each other, it creates what is known as a divergent boundary. When the plates crash into each other, it creates what is known as a convergent boundary. Finally, When the tectonic plates have hot spot, or holes that allow hot magma to rise through the crust to the surface of the earth it is called a hot spot.

We believe that earth was one and all the continents were all together together then something happened that split them up.About 300 million years ago, Earth didn't have seven continents, but instead one huge supercontinent called Pangaea, which was surrounded by a single ocean called Panthalassa. Beyond that, the details get fuzzy. While the heat formed in the mantle likely comes from the when a radioactive substance breaks down of unstable elements, such as uranium, scientists don't agree on whether there are mini-pockets of heat flow within the mantle, or if the whole shell is one big heat conveyor belt.

The tectonic plates are all over the earth’s surface. Over the years, these plates and their characteristics have become common knowledge. These plates move around 3cm at least every year and they move in different directions due to the convection currents of molten magma that flows beneath them. [Raunekk 2010] A convention current definition is “a current in that a fluid is that a results from convection.” [Earth’s dynamic] Then the movement of these plates are the main forces behind catastrophic events such as earthquakes, volcanic eruptions as well as the development of mountains. In addition, this means that these plates are the main reason why our planet surface looks the way it does today. When processes such as pushing, folding and tilting (as well as other forms of tectonic movement) take place, it shapes our planet [Weather Wizkids 2015] as well as playing its part in heating it to an unbearable degree along with the aids of ocean currents. In comparison to the plates that mainly produce heat through its products the ocean current move the heat all over the earth’s surface.

These large sections between he cracks are called tectonic plates. Most of the major tectonic plates are in the Lithosphere- Earth's outermost layer. The major plates in the Lithosphere are the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, Pacific plate and South American plate. The cracks in between these plates are boundaries. There are three main types of boundaries between the tectonic plates. The first is a divergent boundary, which occurs when two tectonic places move away from each other. Volcanic activity is common along this boundary A rift valley can also be created from this type of boundary The next is a convergent boundary, which happens when two tectonic plates come together. There are two kinds of surface feature that are associated with a convergent boundary, deep ocean trenches and volcanic and non-volcanic mountain ranges. The last is a transform boundary, when is when two plates slide against each other. The transform boundary is more commonly known as the fault boundary The most common surface activity associated with this boundary are
