Chapter One Introduction to Geology "study of the Earth." Geology literally means Physical geology examines the materials and processes of the Earth. Historical geology examines the origin and evolution of our planet through time. • Geology is an evolving science - the theory of plate tectonics was just accepted in the 1960’s. • • . Geology seeks to understand the origin of our planet and our place in the Universe - answers to these questions are also posed outside of the realm

the main theories on how dinosaurs became extinct are climate changes‚ an asteroid impact‚ and massive volcanos erupting. Several scientists believe that global and climate changes may have made 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

massive asteroid‚ the eruptions of the Deccan Trap volcanos‚ or the epidemic of diseases. The collision of a massive asteroid is believed to be have instigated the dinosaur elimination. 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

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

specialists shaking their heads‚ a small asteroid completely unrelated to 2012 DA14 struck Earth only hours before the publicized event. The impactor flew unexpectedly‚ literally from the direction of the sun where no telescope could see it‚ and took everyone by surprise as the meteor speckled across the sky above Russia’s Ural Mountains. The large fireball was observed on the morning of Feb. 15‚ 2013‚ in the skies near Chelyabinsk‚ Russia. A relatively small asteroid caused the fireball that entered the
