general they are all different in what they state. Sea-floor spreading states how trenches release magma that adds new oceanic crust. Continental drift states that continents “drift”around earth’s surface and were once part of a supercontinent‚ called Pangaea. Plate tectonics state how different sections of the Earth move around (Continental 1). The theories all represent and state something different‚ and are supported with different pieces of

Would the world be the same if there weren’t plate tectonics? The answer is no‚ because that is how the oceans‚ land‚ and many more things were created. There would be no rocks or plate boundaries. Every living thing on earth would have to adapt to these types of things‚ if there even was living things on earth. The different types of rocks like igneous‚ sedimentary‚ and metamorphic have to go through a process to become that type of rock. Igneous is formed when magma is cooled and

vertebrate animals. The End Triassic extinction took place roughly 199 to 214 million years ago. Its cause was most likely the massive floods of lava that had erupted from the central Atlantic magmatic province‚ which induced the breaking apart of Pangaea and the opening of the Atlantic Ocean. Other scientists suspect that it was the impact of a comet or asteroid that had triggered the volcanism. And‚ lastly‚ the Cretaceous-Tertiary extinction took place somewhere around 65 million years ago‚ and

development of the theory of plate tectonics from Continental Drift to the present The theory of continental drift first came to be in 1915 when Alfred Wegener first proposed his belief that 300 billion years ago there was one single supercontinent‚ Pangaea. At the time‚ most did not believe it was true as he had no proof or idea of how the masses of land would move. However‚ new evidence was put forward over time that fit with Wegener’s beliefs. The first key piece of evidence is the shape of each
