Impact event

(Pasichnyk, 2011), but the 2 theories that have become the most widely accepted as they have the most amount of supporting evidence are the Impact Theory (otherwise known as the Alvarez Hypothesis (Smith, 2005)) and the Volcanic Theory (Pasichnyk, 2011). The Impact Theory states that millions of years ago a comet or an asteroid struck the Earth and the impact of that is what killed the dinosaurs, it also caused the meteor to evaporate covering the earth in a layer of dust (Smith, 2005). In…

Sixty-five million years ago, dinosaurs like the tyrannosaurus rex and the triceratops once roamed the Earth. Suddenly all these great creatures disappeared and it’s not quite sure how they vanished from existence. There are several theories to explain what is known to be the most popular mass extinction of all time. Asteroid The belief that an asteroid struck the planet earth is the most common and most believed theory. This theory has more evidence to back it up than just a giant rock…

and unique theories about the K-T extinction. Some theories have good evidence, others have little to none, but there are no guarantees if the evidence is actually good enough. Many people believe that the great extinction happened because of the impact of a cosmic asteroid and created a massive explosion…

In her book The Sixth Extinction, Elizabeth Kolbert writes that there have been five mass extinctions in the history of planet earth. She asserts that currently the earth is on the precipice of a sixth mass extinction. In contrast with the previous five, according to Kolbert this sixth extinction is almost entirely caused by humans and our exploitation of the earth. In each of the book’s thirteen chapters, Kolbert highlights a particular species that is now extinct and analyzes the causes 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 sound. (6) The earth moves through space in its orbit around the sun at…

It is a common believe that mass extinction on our planet arose as a result of excessive warming and a deep acidification of the oceans. The asteroid theory states that the asteroid impact might have led to vaporization killing dinosaurs on the way. Dr. Keller’s hypothesis states that volcanic activity created a cascade effect that ended up in the extinction of these animals. Either way, experts commonly agree that dinosaurs could not…

the earth. The extinction of this huge animal is a never-ending topic of interest, the mass extension of dinosaurs occurred over a very short geological period. Keywords— Non-Avian Dinosaurs, Mass extinction, Dinosaurs extinction theories; Asteroid impact; Volcanism; I. INTRODUCTION Dinosaurs are the certain group of reptiles which influenced and ruled the earth for more than 160 million years, which are descendant from the species called Archosaurs. These huge reptile creatures were of…

How did the dinosaurs die There are many theories on how the dinosaurs became extinct over 100 million years ago. The theory that is most common, is the asteroid theory. The asteroid theory proposes the idea that an asteroid hit the earth, reduced levels of sunlight, and dropped temperatures, resulting in plants being unable to grow, the plant eaters dying, and leaving no food for the meat eaters. This theory is like a major chain reaction, wiping out every dinosaur on the planet. Another…
