Dynamic Earth Essay Example for Free

Dynamic orb EssayHas the Earth been static since the beginning of time? Well, Earth hasnt been moving vigorously but it is changing at a steady rate. New geological features, careen formations, and locations of plates all rise and demolish some in a lifetime and others over a cover of millions of age. Earth is dynamic it incessantly progresses and doesnt rest. Through the churns and molds, the twists and turns, Earth is active because of plate tectonics and the rock cycle. The whims and theories that put one over up plate tectonics have shown Earths dynamism. The position of plates on global maps didnt always look analogous to the maps shown today. 250 million years ago, there existed a super continent, Pangea, which contained all land masses on Earth. forrader plate tectonics, people thought the plates were always in the same position no one could develop how such a large mass could move. It split up some 200 million years ago but scientists late(a)ly accepted this ide a of moving plates continental drift. Even more recent was the idea of sea-floor spreading, the explanation for continental drift. These ideas merged to create what is now known as plate tectonics.In fact, it is more than likely that Earth will resemble Pangea in the future. The ideas that were brought up could easily have been inside a persons lifetime. Vol tolerateoes and earthquakes are in any case common because of plate tectonics. There are about 500,000 earthquakes and hundreds of minor volcanic eruptions each year caused by the frequent interaction between plates. Plate tectonics are a major piece of evidence for the changing major planet.The transformations that occur through the rock cycle have also shown Earths dynamism. The rock cycle describes the dynamic transitions that the three main types of rock undergo without any definitive order. A metamorphic rock will not always stay a metamorphic rock it can turn into a sedimentary rock through weathering and erosion then com paction and cementation or an torrid rock through melting and cooling of magma.For example, the Andes Mountains were formed by the transformations of metamorphic and sedimentary rock. It began to take its deport form about 80 to 100 million years ago.Even though the process for assortment is prolonged, it takes place nonetheless. The rocks we see today may be different millions of years into the future. Basically, nothing is ever specialise in stone or rather, rock.In conclusion, Earths dynamism is shown through plate tectonics and the rock cycle. It is constantly changing despite the slow rate. The features that are visible today wont be there forever. Volcanoes that were erstwhile active will cease to erupt and continents that were once separated by water will be glued together. Beautiful rock formations will be torn down by the violent planet that is Earth.Due to the changing Earth, our understanding changes with it. Scientists constantly come up with new information to prov e an idea or counter a theory. The winds of change are coming, can you feel it?
