Plate Tectonics Essay

Tectonic Plates Cause of Earthquakes: The earth we live on, is made up of many different materials and layers. 2 of these layers, are the earths crust and mante. The earths crust is the surface of the earth; the outer shell. Just below this, lies the mantle. The mantle is made up of hot rocks, and together the crust and upper mantle, create the lithosphere. The lithosphere is made up of large plates, called tectonics plates, which is the earth’s crust divided. The plates are made of oceanic crust

Plate tectonics occur not only just on Earth, but on other planets in the galaxy as well, such as Venus, Mars, and ancient Mercury. Since there are several planets in the Milky Way that have plate tectonics, it is questionable about if size is a key factor in the likelihood of tectonics on foreign planets. Vol-canoes, mountains, ocean ridges, earthquakes, and tsunamis all would not be possible without the movement of the Earth’s tectonic plates. Dependent upon heat for movement, tectonic plates are

1. Using the diagram above, explain any 3 of the 6 types of tectonic plate interactions. Note: a larger version of this diagram is located in the CONTENT section of this lesson. 1. Convergent Boundary of two Oceanic Plates: When two oceanic plates collide, one of the plates is subducted under the other during the collision. At the subduction zone, a deep trench is formed in the ocean floor. Oceanic and oceanic plate convergence result in the formation of volcano chains. Over millions of years

Question 1: Plate Tectonics (20 points) Plate tectonics is a theory where earth’s crust in the lithosphere is made up of plates that float on a hot layer of molten magma in the asthenosphere, and moves constantly and under different circumstances causes mountains, volcanoes, and earthquakes to appear. With the evidence of plate tectonics and fossils, it is believed that about 225 million years ago, all the major continents had formed one giant continent known as Pangaea. However, due to possible

Theory Change Essay The plate tectonics theory is the theory that the outer rigid layer of the earth is divided into several plates that move around across the earth's surface. There are many topics that support this theory, but I think that continental drift and seismic activity help support it the best. Theories can change over time because people get new understandings of things as time goes by, new knowledge is gained with new technology, and new discoveries can be made. Continental drift is

Study of the plate tectonics of New Zealand has been undertaken since the early 1800s, however the most notable discovery regarding the plate tectonic setting was made in the 1940s by Harold Wellman, who discovered the Alpine Fault. Since then, our knowledge of the plate tectonic setting of New Zealand has been vastly expanded, leading to our present day understanding of the topic. A large part of our present day knowledge of the plate tectonic setting has been gained through the study of active

Earth's tectonic plates. 225 years ago the Earth's continents were joined together to form Pangea (Figure 2). 75 years later they drifted further into Laurasia and Gondwana, if you go along another 50 years it formed continents much similar to ours currently, though Antartica and Australia, North America, Europe and Asia and India were conjoined (Figure 2). The theory of tectonic plates have developed since 1590. This theorem, is currently a key figure of the Earth's natural history. Plate tectonics

this essay I will be telling you about plate tectonics. In my first paragraph, I will be talking about how plate tectonics were discovered. Plate tectonics is theory that earth’s outer shell divided into severally. The mantle plates that glide over the mantle is the rocky inner layer above the core. The plates act like a hard and rigid shell compared to earth’s mantle.The strong outer layer is called litosphere. Developed from 1950’s to 1970’s, plate tectonics is the modern version of continental

The earth is made up of land masses under the crust called tectonic plates. These tectonic plates sit on the upper mantle and lower crust also known as the lithosphere. Tectonic plates are always moving because of the magma churning underneath them in convection currents. Because the tectonic plates are always moving it can cause plates to run into each other which means that one must give way to the other and slide under this can create mountain ranges as the pressure has to do somewhere, this is

The first video was on plate tectonics, the building blocks of earth. The focus was on the interior workings of the earth and it described the movement of the earth and the process of redistribution. The earth is made up of several surfaces and the plates are rigid slabs of solid rock that move around the earth’s crust and upper part of the mantel. They wrap around the globe like a net and interact at boundaries, such as land and ocean. There are three types of place boundaries, convergent,
