Boundaries In The United States And The Galapagos Islands

There are three different types of plate boundaries. The first type of plate boundaries is, the spreading boundary. A spreading boundary is when two plates move apart. The spreading boundary is also known as a divergent boundary. The second type of plate boundary is a colliding boundary. A colliding boundary is when two plates come together, or collide. It is also known as convergent boundary. The third is, a sliding boundary. A sliding boundary is when two plates slip past each other moving in opposite directions. It is also known as transform boundary. Those were the three different types of plate

The creation of the Ring of Fire is very interesting too, it is the result of plate tectonics. These are huge slabs of Earth’s crust that fit together like the pieces of a puzzle. These plates can collide, stay apart, or move up right next to each other. The convergent plate boundaries are formed by plates colliding into each other. The heavier plates slide under the lighter plates causing a deep trench in the ocean floor, as we talked about earlier. If you went down into the ocean you’d be able to see a bunch of trenches in the ocean floor running parallel to corresponding volcanic arcs like the Ring of Fire. This allows islands and continental mountain ranges to be created. A divergent boundary is formed by

Plate tectonics are very dangerous when they collide,slide,and move apart. They can create mountains like the Appalachian Mountains that used to tower over everything then erosion took place. The Appalachian Mountains were formed by convergent boundaries, convergent boundaries are collide

Plate tectonics is the theory that the Earth's crust is divided into a number of plates that move because they float on the asthenosphere. Plate tectonics are moved by convection loops driven by geothermal activity. High temperatures inside Earth causes magma to rise into the asthenosphere and eventually reach the base of the Earth's crust. The magma spreads horizontally and cool. The cooling magma moves parts of the crust, creating mountains (Arbogast 290). There are three types of mountains associate with plate tectonics and they are volcanic, fold and block mountains. These are formed as "compressional forces, isostatic uplift and intrusion of igneous matter forces rock upward" (Williams). Volcanic mountains are formed when a tectonic plate

Separate tectonic plates hold the crust that makes up the continents and the ocean floor

This is a divergent boundary that has continental plates are made out of granite. The plates move apart and make a giant dip in the crust of the Earth. As the plates move apart they form a Rift Valley in the crust and keeps getting bigger, but this takes time.

The plate boundary is located at an ocean trench because both plates are moving towards each other.

Types of plate boundaries can form many volcanoes. These boundaries are called spreading and colliding boundaries. Along the boundaries, a belt of volcanoes starts to form. This is called the Ring of Fire. Along mid ocean ridges, volcanoes form because of spreading boundary. They can also form on land. The next boundary is the colliding boundary. On colliding boundaries, volcanoes form when two plates in the ocean

The plate tectonic theory states that rigid plates slowly ride on the molten mantle. The boundaries between the plates are known to serve as an important mineral resource. Three types of tectonic plate exist: convergent, divergent and transform boundaries. A convergent boundary represents two plates moving towards each other mostly forming a subduction. When two plates move away from each other, a divergent boundary is formed. In transform boundaries, the plates move laterally past each other (Mission, 2016).

On the topic of plate tectonics a convergent boundary is when two or possibly more plates are moving towards each other one going under the other while the other goes over the first. The boundary between the Indian Plate and the Eurasian Plate is a convergent boundary which fuels the formation of the Himalayan mountain range.

Unlike the other three terrestrial planets, Earth’s crust, also called the Lithosphere, is broken into many large plates. These plates are constantly in motion, “floating” on top of the mantle, a layer of molten rock that lays just miles under the lithosphere. Even though the plates are constantly in motion, there is only a few centimeters of change every year. The seven major tectonic plates are known as the African Plate, the Antarctic Plate, the Eurasian Plate, the Indo-Australian Plate, the North American Plate, the Pacific Plate, and the South American Plate. Along with the seven major plates, there are several smaller plates. The surface of the Earth is constantly changing due to the movement of these plates. There are four different types of plate boundaries. Plate boundaries occur where the edges of two tectonic plates interact with each other as the plates move. Divergent boundaries occur when two plates move away from one another. Oceanic crust is created at divergent boundaries when magma from the mantle reaches the surface and hardens. Convergent boundaries occur when two plates move toward each other, causing mountains and volcanoes to form. Subduction boundaries occur when an oceanic plate moves under a continental plate, resulting in violent earthquakes and volcanoes. Transform boundaries occur when two plates slide against each other. Transform boundaries result in the strongest earthquakes and fault

This can occur when weak regions of the crust give way as the result of pressure exerted from the mantle or in regions near plate boundaries.

In this mantle, there are convection currents. Heat from the core causes convection currents to slowly move the Earth 's crust around. All over the crust’s surface, crust is destroyed, and reformed. All plate boundaries movements are moved by convection currents in the mantle. At the boundaries between plates, magma is able to force its way to the surface and escape as lava. There are three different types of plate boundaries known as convergent, divergent, and transform.

The theory of plate tectonics also explains the formation of destructive plate boundaries which account for creating 80% of the world’s active volcanoes. The melting crust at Subduction Zones (oceanic-oceanic or continental-oceanic) are due to differences in density between oceanic and continental lithospheres, where the less dense plate is pushed beneath the more dense plate, and becomes part of the asthenosphere forming magma that is andesitic in its nature. This creates the most violent volcanic activity. Island Arc volcanoes such as Pinatubo and Fold Mountain Volcanoes such as Nevado Del Ruiz (Andes) are very destructive.

A divergent boundary in plate tectonics is also known as a constructive boundary. It exists when two tectonic plates are moving away from each other and create rift valleys. This usually occurs between oceanic plates. The sea floor spreading is an example of divergent boundaries. An underwater chain of mountains
