Geological history of Earth

two asteroids that almost were formed into planets. Ceres is now considered a dwarf planet and Vesta has similar geological features that resemble Earth’s surface. Folger Begins to tell us about Marc Rayman who is a chief engineer for a NASA mission that launched a spacecraft known as Dawn into space to head towards both Ceres and Vesta in 2007. Folger then tells us about the history of Ceres and Vesta. He informs us that Ceres was discovered in 1801 and Vesta was discovered in 1807. At first…

discovery of this theory started an uprising in the study of earth sciences. Between now and then, this theory has been confirmed by scientists, who are able to formulate a much better understanding of how plate tectonics shaped the way our planet is today. It is now knows that plate tectonics has or has had at least some influence over almost all geologic processes. AS I’m sure you can imagine, the idea that the entire crust of the earth constantly shifts has dramatically altered the way we…

agriculture, and for everything in between. However, ever since 2011 the once luscious west coast has been getting increasingly drier and drier each year. Due to lack of water and rainfall, 2015 is the fourth year of the worst ongoing drought in the history of California. The now doubled population of California from 50 years ago does not lessen the strain whatsoever.…

the 1440s, reproducing a book would take, depending on its size, from several months to several years. After the 1440s, in Europe, Johannes Gutenberg invented the printing press which turns out to be the one of the most important inventions in the history. The most important consequences of the printing press were the increasing efficiency in copying pieces of writings, the increment of literacy and the religious reform. The increasing efficiency in copying pieces of writings is one of the most…

discipline in Britain. She was the first recognised by the Geological Society of London, and credited with the first discovery. She was credited with the first discovery of a complete Plesiosaurus skeleton. Mary Anning was one of the earliest fossil hunters to identify these prehistoric fossils, and she shared her specimens and impressive knowledge about them with scientists at the time. What made Anning discoveries so important to the history of science, is that they provided evidence that…

acknowledged thaDinosaurs roamed the earth for 163 million years.(Dinosaur Worlds). They thrived as one of the most successful groups of animals in the history of life on land(PBS). Then, 66 million years ago, the last group of dinosaurs disappeared forever; leaving us with the question - what killed the dinosaurs? And how did they disappear? Was a gradual or a quick and calamitous end? The “Cretaceous-Paleogene (K-Pg) Extinction Event took such a significant blow to life on Earth it marked the…

Perhaps one of the most puzzling questions throughout modern history is how the universe came to be. When discussing the creation of the universe and humanity, it becomes rather difficult to have the ability to defend one’s own beliefs, regardless of how correct they believe themselves to be. Proponents of theories that involve naturally caused reasons for the creation of the universe are those who appear to have the most empirical and practical evidence. Completed studies and observations over…

who visit the Grand Canyon often visit the South Rim. While the north Rim is 250 miles away and is more remote. The Grand Canyon has many artificial lakes formed from the dams on the Salt and Colorado rivers. The park protects many animals and geological evidence from the rock layers. One quarter of the Grand Canyon is occupied by the Indians, the most in any state, by far. Some of the tribes consists of the Navajo, Apache, Hopi. The canyon has a few national monuments, such as the…

named Holocene by the scientists (McNeill and Engelke 1). Holocene (entirely new) period is impressively highlighted for its cultural and anthropomorphic spirits as the main advancements of humanity took place specifically at this period of human history. Holocene epoch is also known for the valuable works of art and literature that were created during this period. The stable climate became the main engine of the transition of the human beings from hunters and gatherers to civilized city…

major issue being people feel that there other pressing matters that need scientist need to pay attention to rather than focusing on trying to get to Mars. An example, some feel that the scientist should focus on observing Earth, because due to neglect an aging fleet of Earth orbiting satellites is leading to a significant degradation of human ability to measure changes in Earth’s climate. However, some believe that if NASA diverts its attention and resources not to a mission to Mars, but a…
