Chicxulub crater

over the world are planning to drill core samples from the famous dinosaur asteroid crater, the, to help them in the adventure to study the evolution of life on Earth, as well as how the crater was made. The team will drill 5,000 feet down into the crater, which is thought to be at least 65-million years old, dating back to the start of the extinction of the dinosaurs. Most now believe that the asteroid that caused the crater was the cause of the dinosaur extinction. This adventure to drill into Chicxulub Crater to get the core sample is expected to cost $10 million and is led by two scientists: Joanna Morgan from Imperial College in London, and Sean Gulick from the Austin Institute of Geophysics at The University of Texas. By going down to that deep of a distance, they will travel to an area of the Earth…

Stage One - The Chicxulub Impactor Origin Theory and how Asteroids enter the Earth's Atmosphere. Origin Theory The Chicxulub Impactor is an asteroid whose origin is unknown. A theory orchestrated by David Nesvorný, William F. Bottke and David Vokrouhlický however suggests that it is part of the Baptistina family of asteroids which was the result of a collision in the Asteroid Belt 160 million years ago (2). This theory is supported by the evidence of carbonaceous material that is present in…

Stage 1: What caused the Chicxulub Impactor to enter the Earth’s atmosphere and hit Earth (2) About 65 million years ago an asteroid that is roughly 10 kilometres across, hit Earth on the coast of the Yucatán Peninsula in Mexico. It caused a huge explosion and left a crater that is about 185 kilometres across. This asteroid impact is commonly known to be the reason for the extinction of three quarters of the dinosaurs. (4) The asteroid soared through the sky at more than 40 times the speed of…

190 million years ago. It could have separated the species of animals and startled their ecosystems (Nardo 43). One of the most important factors is the possible meteorite impact. There are numerous theories and evidence for the possible meteorite crashing. In 1989 the University of Arizona’s students Alan Hildenbrand and WIlliam Boynton discovered evidence of huge tsunamis that swept over the coasts of Mexico, Cuba, and the US by a large object (Nardo 60). In 1991 scientists from NASA…

explaining the spike in iridium in the KT boundary. This theory is further supported by the existence of shocked quartz found in the boundary around the world. The shock quarts appeared due to intense pressure, presumably from the impact. a large piece of evidence is the massive crater found Chicxulub, Yucatan, Mexico. This is the assumed to be the crater of the life-ending meteor. There are other theories that are as closely considered, for example, there is a theory that flowing plant life…

For this project, I read, “The End Of Dinosaurs, Chicxulub Crater and Mass Extinctions.” This book began talking about the five mass extinctions and what a mass extinction was. It stated that the best studied of all mass extinctions was the fifth mass extinction. This is because it was the closest to us in time, and it wiped out roughly 70% of all species. This lead to the books next topic, how this mass extinction occurred. In the beginning, most scientists were gradualists, meaning they…

after most of the dinosaurs died out there was nothing to evolve. With this theory it’s actually called the Alvarez Hypothesis with this they’re exact theory states “The Alvarez hypothesis says that the mass extinction of the dinosaurs and many other living things during the Cretaceous Paleogene extinction event was caused by the crash of a large asteroid” The Evidence that they have indicated that the asteroid fell in the Yucatán Peninsula, at Chicxulub, Mexico. The theory is named after the…

Today, we know this asteroid as the Chicxulub asteroid. This asteroid caused the extinction of most of the dinosaurs on Earth. As stated by Alexander, “Tourists now enjoy the sunshine and warm waters here, but 66 million years ago, it was dinosaurs that claimed their place in the sun” (Alexander 2). The asteroid also caused other chaotic events when it struck the surface of our blue and green planet. As said by Reynolds, “The consequences for everything in the region were terrible, and a…

scientists into reaction and then action.”(Wilford, John Noble.) Many scientists have created new theories and hypothesize, some have been backed up with evidence while others are pure imagination. The first and most evidence backed theory is called the K-T event theory. This theory was created by a father and son duo Luis and Walter Alvarez. “In the 1980s, father-and-son scientists Luis (1911-88) and Walter Alvarez (1940-) discovered in the geological record a distinct layer of iridium–an…

dinosaur on the planet. Another theory, also with not as much evidence, is the volcanic eruption theory. This theory suggests that a volcano erupted from underground spreading ash into the air, consequently reducing levels of sunlight and dropped temperatures, and like the asteroid theory there would not have been any plants for the dinosaurs, resulting in the extinction of all dinosaurs. The asteroid theory has the most accurate evidence, suggesting that this theory was the correct approach to…
