Dynamic Earth Essay

Has the world been static since the stolon of time? Well, Earth hasnt been moving vigorously but it is changing at a steady rate. New geological features, contention createations, and locations of plates wholly rise and demolish some in a lifetime and others everywhere a span of millions of age. Earth is dynamic it constantly progresses and doesnt rest. through and through the churns and molds, the twists and turns, Earth is active because of plate tectonics and the rock cycle.The ideas and theories that make up plate tectonics have shown Earths dynamism. The position of plates on global maps didnt always look similar to the maps shown today. 250 million days ago, there existed a super continent, Pangea, which contained all land masses on Earth. Before plate tectonics, people thought the plates were always in the alike position no one could explain how such a too large mass could move. It split up some 200 million years ago but scientists recently accepted this idea of m oving plates Continental drift. Even more 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 pass on resemble Pangea in the future. The ideas that were brought up could soft have been within a persons lifetime. Vol corner pockoes and earthquakes ar excessively 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. shield tectonics are a major piece of evidence for the changing 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 forget not always stay a metamorphic rock it can turn into a sedimentary rock through weathering and erosion past compaction and cementation or an igneous rock through melting and temperature reduction 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 process for change 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 one time 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. referable to the changing Earth, our understanding changes with it. Scientists constantly come up with new nur ture to prove an idea or counter a theory. The winds of change are coming, can you feel it?
