Geography EssayPlate Tectonic and LandformsThe Earth is full of so many beautiful landforms, such as, high mountain ranges,volcanoes, and rift valleys. But how are these geographic features created? Landformsare created by the Earth’s tectonic plates which are constantly moving. Depending onthe types of plates we are dealing with, we receive different landforms. The movementof these plates are caused by the inner structure of our Earth. The tectonic plates haveshifted so much since the beginning of the Earth’s history that we were once asupercontinent called Pangea.Looking at a world map we can see that the continents look like a jigsaw puzzle; theway South America’ East coast can algin with the West coast of Africa, and how Antarcticaand Australia edges look like a perfect fit.This is the outcome of the continental drift ofPangea. Looking at a world map we can see that the continents look like a jigsaw puzzle;the way South America’ East coast can algin with the West coast of Africa, and howAntarctica and Australia edges look like a perfect fit.This is the outcome of thecontinental drift of Pangea. Pangea was a continuous landmass consisting of our presentday seven continents, existing approximately 280 million years ago (United StatesGeological Survey, n.d.). The evidence that supports Pangea is found in the types of rocksand fossils found on the modern-day continents. There are three types of rocks geologistlook for, igneous, metamorphic, and sedimentary; Each type of these rocks is formed indifferent ways. Igneous rocks are formed from magma once it starts to cool and harden, itforms crystalized or glassy looking rocks, such as the gemstones garnet and spinel (Kudo,2020). Sedimentary rocks are created from previously existing rocks that have been erodedby nature then the particles settle together losing moisture to form a new rock, with the
