Dynamic Earth Essay

Has the basis been static since the beginning of time? Well, nation hasnt been moving vigorously merely it is ever-ever-changing at a truelove rate. New geological features, thrill varietyations, and locations of home offices all told rise and demolish more(prenominal) or less in a lifetime and others over a span of one million millions of age. country is dynamic it unceasingly progresses and doesnt rest. Through the churns and molds, the twists and turn of eventss, Earth is prompt because of surface tectonics and the rock cycle.The estimations and theories that organise up collection plate tectonics get under whizzs skin shown Earths dynamism. The position of plates on global maps didnt always take care similar to the maps shown at present. 250 million years agone, in that location existed a super continent, Pangea, which contained all reduce masses on Earth. Before plate tectonics, people thought the plates were always in the same position no one could exp lain how such a grownup mass could move. It split up some 200 million years ago but scientists recently accepted this stem 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 know as plate tectonics.In fact, it is more than likely that Earth give tally Pangea in the future. The ideas that were brought up could easily befool been within a persons lifetime. Volcanoes and earthquakes are also 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. household tectonics are a major piece of evidence for the changing planet.The transformations that devolve by the rock cycle squander also shown Earths dynamism. The rock cycle describes the dynamic transitions that the three main(prenominal) types of rock undergo without any classical order. A meta morphous rock leave alone not always stay a metamorphic rock it can turn into a sedimentary rock through weathering and erosion then compaction and cementation or an igneous rock through liquescent and cooling of magma.For example, the Andes Mountains were formed by the transformations of metamorphic and sedimentary rock. It began to take its present form about 80 to 100 million years ago.Even though the play for transfigure is prolonged, it takes place nonetheless. The rocks we see today may be different millions of years into the future. Basically, nothing is ever set 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 once active willing cease to erupt and continents that were once degage 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 prove an idea or counter a theory. The winds of change are coming, can you feel it?
