Geological history of Earth

Since the discovery of fossils in the early 19th century, people have wondered how the dinosaurs went extinct. Many theories have since come about, however, even today we cannot be sure what exactly whipped out these magnificent and colossal beings. In 1679, Robert Plot found and sketched a thigh bone which he believed was from the skeleton of a giant man This fossil has since disappeared, however the drawing remains and seems to suggest it was actually a part of a megalosaurus. In 1822, Mary…

juvenile crust which was eventually accreted onto the Archean Superior and Hearne cratons as well as a number of smaller cratons including the Sask Craton (Lewry et al.,1994). The THO preserves a relatively complete tectonostratigraphic evolutionary history including evidence for rifting (ca. 2450-1950 Ma), the formation of oceanic crust (ca. 2000-1800 Ma), and sedimentary assemblages deposited along continental margins and younger (1880-1830 Ma) collisional and foredeep basins (Ansdell, 2005).…

studied for hundreds of years about global warming,but some people criticize millions of scientist for global warming but it is caused from nature therefore its a natural occurrence. Global warming should be viewed as a natural occurrence. Issue#1:History temperatures decline: the planet in 2014 was the warmest in 135 years of record keeping US climatologists said.Averages in that year were 1.24 degrees higher than 20th century average of about 57 according to the National Climatic Data Center…

temperature of the Earth 's atmosphere and its oceans,a change that is believed to be changing the climate of earth ( Livescience.com ). It has been a global issue for a long time now. It has led to many global problems that are very dangerous to all people. Some historical background of global warming is , ever since the 1880’s earth 's temperature has been gradually increasing which is impacting the whole world and makes sea level rise which can lead to many problems. Earth 's climate has…

considered a World Heritage site because of its rich treasures. These rich treasures are the cultural and natural heritage sites that are irreplaceable sources of life and inspiration. And it is because of the churches erected by the Spaniards, and the history that lies in the place. Places as unique and diverse like Paoay Church that has a unique combination of baroque and oriental styles, and Vigan, the Intramuros of the Ilocos, when I compare this to heritage place also makes Ilocandia a…

not be the sole reason of why the dinosaurs may have become extinct. These massive volcanic eruptions are said to have begun 250,000 years before the mass extinction event, and would have lasted a total of 750,000 years, which is fairly short in geological time. These volcanic eruptions have been thought to have led to the extinction of the dinosaurs in many different ways. Firstly, the massive number of volcanic eruptions are presumed to have produced enormous…

and can be easily refuted. The NCSE and VBOE need to look more in-depth at the pros and cons of including intelligent design and creationism into the classrooms of public schools. Genesis 1:1 says “In the beginning God created the heavens and the earth.”(NIV) This is the foundation of creationism and intelligent design but it is dismissed by evolutionists because it is not considered scientific. Evolutionists claim that there can be no evidences found to support creationism and intelligent…

Mars being the greatest subject of interest. This is due to the existence of water ice on its surface, and water vapour in its atmosphere. The existence of water is pivotal in the exploration of Mars, as it may hold vital information regarding the history of the planet. Scientists have implemented the ideology to ‘follow the water’, as the existence of water allows for life to grow, and more importantly, exist. This is reiterated in Rothschild and Mancinelli’s “observation that all terrestrial…

across the earth 's surface relative to each other, like big pieces of ice on a lake. If we were able to lay the earth flat to see where the plates were positioned, it would have the appearance of an orange peel; with the earth 's crust as the orange color shell and the white as the lithosphere. The break points would be fault lines, the plate’s outer perimeter that aligns and intersects them. In its early history, geologists believe that the continents and ocean basins of the earth did not…

California Gold Rush is arguably one of the most important events in United States history. The gold rush caused what is considered to be the largest mass migration in United States history, bringing in 300,000 people by 1855, 25% of whom were immigrants from other countries. Not only was California rich in people, it was rich in gold. Approximately 750,000 pounds, two billion dollars’ worth, of gold was extracted from the earth from the time gold was first found in 1848 to the time the rush…
