Five extinctions of Earth and Who will be Next? The Earth we live on now is drastically different from how it was millions of years ago. The Earth has gone through many changes and events though time. There are five major events in history that have changed the world. Without these five mass extinctions who knows what Earth would have looked like, and if humans would even be alive. In the ordovician period 439 million years ago there was a mass extinction that wiped out 89% of life on Earth.…

Did one single disaster cause the K-T extinctions? Some scientists and people are committed to just one reason the K-T extinctions occurred but in this paper many possibilities will be explored with evidence to back up why they could have been a cause as well to the extinctions. Everyone will ultimately make his or her own decision/thoughts on what could have happened, and of course all hypotheses would be subject to analysis. Asteroid impact theory. The impact of a 10 km+ asteroid would blow a…

offered a diverse possibility for ecological expansion for many new species. This reason states that this can’t happen again because the world will never be that empty again. This goes along with the idea of Darwinism. The bursts of life after the Permian extinction quantitatively matched up with the Cambrian explosion, but not qualitatively. The second reason is that genetic changes were more “acceptable” back during the time of the Cambrian explosion. Now, genomes are very intricate and…

Lewis Lapham says that sports must preserve an illusion of perfect innocence. Sport activities are described as a ¨ritual portrayal of a world in which time stops¨. Lapham is absolutely right when he says this, games are not just games for a lot of spectators. High school sport games are something else, they do not exactly provide hope, but a false or temporary hope. People always know the game is going to have to end, but they still enjoy what they have left. In H.G. Bissinger’s Friday…

these two places. There are no eutherian mammals indigenous to Australia because these mammals were indigenous to Asia and North America, but since all the continents had been joined together, they migrated to land that is now Australia. The Permian mass extinction happened around the same time that enormous volcanic eruptions in Siberia had been going on. Beides excessive amounts of lava and ash being dispersed, the eruptions might have produced enough carbon dioxide to raise the…

New Yorker. The Sixth Extinction won the Pulitzer Prize in 2015; I chose this nonfiction book because I hadn’t heard of the concept of a sixth extinction. I had previously learned of multiple extinctions that occurred in the Cretaceous, Ordovician, Permian, and Triassic-Jurassic periods, but I became curious just by the thought of what Kolbert meant by a sixth extinction. She claims that this extinction could be the most devastating yet due to humans, and gives different descriptions of species…

the stratigraphic log plotted with temperature for the AET-4 well (Figure 4.6, from Shevenell et al., 1988 – Figure 3). The figure illustrates how the gradient changes with lithology in the Permian section and fluid flow. However, the E10 and Paliza Canyon wells are too shallow and do not penetrate the Permian section and the Triassic section was mostly removed at the AET-4 location prior to the deposition of the Bandelier Tuff; thus direct comparison with the lithologic log at AET-4 is not…

“Life as we know it would be impossible if ecosystems collapsed” (Jerry Coyne). Granted that humans depend on every natural service that the Earth provides for us, however, we continue to live a destructive way of life without realizing the consequences. “Scientists agree that we’re now in the midst of a sixth [mass extinction]” (Jerry Coyne). Every year, 30,000 species go extinct due to the hazardous effects of human activity on wildlife. At this rate, the sixth mass extinction could happen…

When you think think of high school what come to your mind? Parties every week,dances, or going to your school's football games. What if it was the reverse of all of that, mass fights at sporting events, over 100 arrests due to alcohol. These situations have been going on at Smith High School for the past couple of weeks. Problems with violence and alcohol abuse have spun out of control,so the school has taken drastic action to stop it. The school has introduced a new conduct toward student…

important as the oil and gas market continues to fluctuate. Apache is an oil and gas exploration company based in Houston, Texas. Apache is a global company with oil reservoirs all over the world. Although most of their oils till comes from the Permian basin in west Texas, they also have sizable holdings in the middle east. Almost 30% of Apache’s oil production comes from the oil contracts in Egypt. Their mission statement according to their website is: “Our mission is to grow in an innovative,…
