Pangaea

The Inner Core, Outer Core, Mantle, Asthenosphere, and Lithosphere, or, as more colloquially known, the five layers of the Earth. Although each layer is important, each living thing resides on the Lithosphere, which happens to rest on the Asthenosphere, the upper part of the Mantle. Forces caused by these two layers both contribute to the theory of Plate Tectonics, which happens to be interconnected to Earthquakes and Volcanoes. Without Plate Tectonics, the other two occurrences simply cannot…

Plate tectonics play a fundamental role in climate change around the globe. More than 200 million years ago, the continents were merged together as one giant landmass called Pangaea (Cosmato,2016). As the continents moved, their positions on Earth changed, and so did the movements of ocean currents. Both of these changes had effects on climate. Plate tectonics affect climate by different movements (vertical and lateral) both in which affect air circulation. Vertical movement of the surface…

Jerry Coynes', Why Evolution is True, had the instinctive capacity to utilize science as the perfect means to force me to question everything I had been taught about evolution. He presents and explains his ideas about evolution systematically and in detail. While reading each chapter, I was able to reflect on my personal evaluation of “Why Evolution is True” based on Jerry Coyne’s words and ideas. The idea of evolution is met with much defiance for several reasons. Coyne explains why he feels…

Number 1:The Ordovician Silurian extinction This extinction happened about 439 million years ago because of a drop in sea levels as glaciers formed. An ice age has been blamed for the cause of the extinctions. A large ice sheet in the southern hemisphere caused climate change and a decrease in sea levels. A combination of this lowering of sea level caused a reduction in ecospace on continental shelves, and the cooling caused by the glaciation itself are some of the big factors for the…

South and North America began accumulating rapidly. This eventually led to tout modern nations that we know of today. Columbus also started the Columbian Exchange. After Columbus sailed the ocean it no longer was a barrier for people. It was if the Pangaea had been reconnected again. A century later after Columbus found the Americas’, the world was looked at very differently. The Spanish Sailed to china to give them silver and in return we received silk. Columbus started an exchange which had…

glaciers will generate more water for these rivers but as the glaciers shrink the melting will decrease. India is a plateau country, that is strongly dominated by the massive Deccan, which are sheets of lava that were poured out during the breakup of Pangaea. Many civilization have emerged in this region, the first civilization emerged in the Indus Valley. This civilization was characterized by being the most complex and advanced technologically. This civilization emerged along the same time…

The theory that today's continents were once part of a more complex and large super-continent, also referred to as “Pangaea”, was first introduced by Alfred Wegener. Wegener, the German meteorologist and geophysicist, formally initiated the detailed hypothesis that the once intact, large, continent had slowly drifted to their present positions. Although others brought fourth evidence, plate tectonics processes and continental drift was not of interest until the late 1950s, when scientists…

Who was Alfred Wegener? Alfred Wegener was born in Berlin, Germany on November 1, 1880. He was a meteorologist (a person who studies the atmosphere and its weather (Meteorology, n.d.)) and geologist (a person who studies about the Earth’s history through rocks, layers of soil, etc. (Geology, n.d.)). In the early twentieth century, Wegener championed the continental drift theory. In 1904, he attended University of Berlin, where is he studied natural sciences also, received his doctorate in…

This thought was advanced by Alexander de Toiu in the year who interpreted that the pre-existing super-continent, Pangaea, first broke into two; Laurasia in the northern hemisphere and Gondwanaland southern hemisphere. These landmasses further split up to form the nine continents which exist today. Therefore, Asia, Europe, North America and Greenland that exist in the…

Introduction Geologists explanation how the Earth's surface behaves by plate tectonics theory. According to the theory, the surface of the Earth is broken into large plates and size and position of these plates change over times. The edge of these plates is the place where intense geologic activity happens. Such as earthquakes, volcanoes, and mountain building occur in areas where they move against each other, A first theory of continental drift is proposed by German scientist Alfred…
