Dynamic Earth Essay

Has the primer coat been static since the beginning of sequence? Well, Earth hasnt been moving vigorously only it is changing at a steady rate. mod geological features, shiver formations, and locations of racing shells all rise and cashier some in a lifetime and others everywhere a span of megs of yrs. Earth is dynamic it unendingly progresses and doesnt rest. Through the churns and molds, the twists and turns, Earth is active because of dental domicile plate tectonic theory and the rock cycle.The ideas and theories that make up plate tectonics claim shown Earths dynamism. The rig of plates on global maps didnt ceaselessly gestate similar to the maps shown today. 250 one thousand thousand years ago, there existed a super continent, Pangea, which contained all land thronges on Earth. Before plate tectonics, people thought the plates were eternally in the same position no one and only(a) could explain how such a large mass could move. It split up some 200 million y ears ago but scientists recently sure this idea of moving plates continental drift. Even more than recent was the idea of sea-floor spreading, the explanation for continental drift. These ideas co-ordinated to create what is now known as plate tectonics.In fact, it is more than likely that Earth give resemble Pangea in the future. The ideas that were brought up could easily have been within a persons lifetime. Vol flockoes and earthquakes argon also common because of plate tectonics. There argon about 500,000 earthquakes and hundreds of minor volcanic eruptions each year caused by the frequent interaction between plates. home base tectonics are a major cut of evidence for the changing planet.The transformations that occur by dint of the rock cycle have also shown Earths dynamism. The rock cycle describes the dynamic transitions that the three main(prenominal) types of rock undergo without any definitive order. A metamorphic rock exit not always stay a metamorphic rock it ca n turn into a sedimentary rock through weathering and erosion then compaction and cementation or an flaming rock through melting and cooling of magma.For example, the Andes Mountains were create by the transformations of metamorphic and sedimentary rock. It began to take its resign form about 80 to 100 million years ago.Even though the process for channelize is prolonged, it takes place nonetheless. The rocks we see today may be different millions of years into the future. Basically, nothing is ever pose in stone or rather, rock.In conclusion, Earths dynamism is shown through plate tectonics and the rock cycle. It is constantly changing despite the disinclined rate. The features that are visible today wont be there forever. Volcanoes that were once active will cease to erupt and continents that were once separated by water will be glued together. glorious rock formations will be torn eat by the violent planet that is Earth.Due to the changing Earth, our understanding changes with it. Scientists constantly come up with modern information to prove an idea or return a theory. The winds of change are coming, can you feel it?
