Earth Essay

The science that is connected with planet earth encompasses geosciences or earth science among others. Containing old histories, this is considered as a part of planetary science while it possesses holistic and reductionist approaches in the science of the planet Earth. This discipline can cope with lithosphere, atmosphere, biosphere or hydrosphere. Quantitative understanding has been developed by the scientists to understand the ground systems with the tools by mathematics, physics, chronology, biology, chemistry alike that help to know how the universe is evolved.

James Hutton was the first scientist to address the Earth was millions of years old, as well as alive and is continuously being formed. Charles Lyell popularized uniformitarianism, and believed the Earth was being shaped by slow moving forces. Alfred Wegener introduced the foundation for the theory of continental drift. Wegener was one of the first to recognize and have an understanding of how the Earth works which required data and information from earth sciences. In the 1960s, the theory for the continental drift became known as the theory of plate tectonics or plate building.

Imagine waking up and looking around, only to realize that while you were asleep ninety percent of the world population had vanished. In the novel Earth Abides, George Stewart creates this scenario and makes it a reality. The novel is centered on the life of Ish, who wakes up only to find he is one of the few left on earth. Having to survive and adapt, Ish is faced with the responsibility of making contact with other survivors of the Great Disaster. In doing so, Ish meets several characters and together they form a tribe to fit the new lifestyle. Ish becomes the leader of the group and the main focus of the story; however, he is not the only important character.

Movements and interactions in the lithosphere and the internal Earth processes that drive them are referred to as the _____ cycle.

Continental drift was a theory offered by Alfred Wegener in 1912 that hypothesized that all the continents at one time fit together as one land mass. Wegener, explained that the ends of each continent could fit together like a puzzle and that over time the continents drifted apart. "The model explained why the same types of fossils occur in sedimentary rock on both sides of the vast Atlantic Ocean" (Star, 2008, pg. 250), in other words allopatric speciation. Wegener's theory did not have a supporting geological mechanism. Many years later and advances in technology brought about the plate tectonics theory. Essentially it says:

A German meteorologist and explorer Alfred Wegener put forth the theory of continental drift in the early 1900’s. Wegener pointed out that the earth’s continents looked as if they were all connected at one point in time. He also pointed out that some of earth’s features, including the long S-shaped mountain structure formed on the Atlantic seafloor, could fit snugly against the corresponding western seafloor of Europe and Africa (Sieh and LeVay 1998). Wegener proposed that all of the earth’s continents once formed one single landmass, which he named Pangaea or “all-land”. He concluded that Pangaea had broken up and separated due to the unidentifiable forces estimated 300 million years ago (Sieh and LeVay 1998). Geologists did not fully understand at the time that Earth’s continents could drift (Hazen 2012). After all, the continents do not float in the oceans. They are made from a solid material connecting to the mantle, a sphere of solid rock

H-O-M-E 4 letters with deep meaning. Home is our shelter, our family, and place where your heart is. Earth is our home, our live depend on what the earth provide and we cannot live a second without the thing that the earth provides. At the beginning, God have created the earth completely balance with its function. The forest stands as the heart of the earth because trees provide human oxygen and absorb the carbon dioxide. The earth cooled, the water vapor condensed and fell in torrential downpours at the right distance of the sun not too far and not too near. The earth perfect balance enables to conserve water. The water cut channel is like the veins of the earth body. Everything has been designed perfectly link to each other’s. We cannot imagine if the living things in the earth did not link to each other, how can a human survive. Trees cannot live without water and sun, Human

Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad.
