Pangaea

German geophysicist Alfred Wegener had thought of a theory known as continental drift. He had believed that the continents are mobile and move over time, drifting on earth’s surface. It is thought that the continents have been one continent at some point in the world, combined. Pangaea, although highly controversial, is a legitimate moment in history. It is sought to be the countries were once one at some point. Alfred Wegener noticed that the countries seemed to fit together like a puzzle, this is known as a large continental mass, also known as a supercontinent. A supercontinent had been named Pangaea, which means ‘whole earth’. Ural Mountains separate supercontinents which were formed by two land masses colliding. After the separation,

Earth's floor then is sucked into deep ocean trenches creating a force, this called subduction. As two rock plates slide past one another a crack or fault develops, which prevents energy to form an earthquake. One of these plates are called Tectonic Plates. Tectonic Plates are pieces of crust moving around earth, pushing together, pulling apart and sliding past each other. The second plate is Plate Tectonics. This is when earth's crust is made up of rigid plate that "float" on molten layer of the mantle beneath earth's crust. Oceanic- oceanic plate is a similar plate that sinks under the other when the two plates converge. With these plates in motion, causes movement and the split of continents. As one plate moves, it cause other plates to move. The split between supercontinent led to divergent evolution, unique species formed in response to different environment conditions, this was the height of the age of

This began a theory on dinosaur extinction. Geologists believe that the large meteorite that struck Mexico Yucatan Peninsula caused extinction which led to 70% of plant and animal life dead. It is believed that this occurrence had caused the extinction of dinosaurs. Dinosaurs have been extinct for millions of years. It was believed that asteroid had wiped out dinosaurs. With the force of an impact, it had prevented carbon to liquefy deep in earth's crust. The liquefying in earth’s crust formed tiny airborne beads. The beads, known as carbon cenospheres, could not of formed from plant matter countering a hypothesis that the cenospheres are the remains of an earth on fire. These beads were left next to a layer of iridium which was an element likely to be found in solar system's asteroids. Iridium, in earth's core, could have been exposed when an explosion occurred. Iridium’s core contains magma that scientists think spread. Tektite is a type of rock that most scientists believed formed by the impact of meteorites on earth's surface. This rock causes an enormous explosion when it hits ground. If any living specie was near this rock when it had exploded, would have been killed
