Although all arguments are credible‚ and supportive with educated information and data‚ the most conclusive theory of all is The Alvarez Asteroid Impact theory. Alvarez‚ a researcher at the University of California‚ discovered a pencil thin layer of Iridium around the rocks in Gubbio‚ Italy. (New Scientist‚ 1) Iridium is an element found in meteorites and asteroids. In 1980 it was proven that the layer if Iridium was evidence of a huge comet or meteorite that crashed into the earth sixty five million

However‚ the solar system also consists of moons‚ asteroids‚ comets‚ minor planets‚ dust and gas. The sun makes up 99% of all matter in the solar system while nearly all of the remaining mass is contained in the planet Jupiter. The solar system is located some 26‚000 light years away from the centre of the

Cretaceous period are the asteroid‚ the volcanoes‚ and the major climatic changes. The most popular "disaster theory" for the extinction of the dinosaurs is that the Earth was hit by an asteroid or a comet 65 million years ago. The impact was proposed by a Professor of geology from Berkeley‚ California‚ Walter Alvarez. Alvarez’s conclusion about the extinction was "A giant meteor had struck down the world of dinosaurs" (Bakker 432). Alvarez believed that " a huge meteor (or asteroid)‚ smashing into the

Introduction: I have decided to answer this question‚ as the extinction of dinosaurs has interested me since I was very young and I thought that by answering it‚ I could learn a lot more about what happened and broaden my knowledge of the subject! Answering about the dinosaurs would also keep me interested in the topic as I am working on it and I do not fully understand many parts so as I work on the case study I can learn more and stop myself from becoming bored. The subject has no concrete answer

First of all an asteroid is a "minor planet‚ small body orbiting the sun" ("asteroid”) .There are many asteroids in space. Scientists believe that earth was hit by an asteroid that was over six miles wide‚ or that earth was hit by a comet travelling 18 miles per second. They contemplate that when the asteroid hit earth’s

Pioneer 10 had three primary goals: make in situ measurements of Jupiter‚ study the asteroid belt‚ and investigate the planetary medium. The first‚ to make in situ measurements of Jupiter‚ included taking measurements of and understanding the planet’s atmosphere‚ take close-up images of the planet‚ and continue on to fly past Saturn. For the second goal‚ the asteroid belt is the circular groupings of asteroids and small planets in

This would provide an explanation for the earthquake‚ the blotting out of the sun and the appearance of the moon as blood red due to the large amount of debris in the atmosphere. The impact
