What is Sea-floor spreading? Seafloor spreading is a process of plate tectonics in which new oceanic crust is created as large lumps of the Earth ’s crust split apart from each other and magma shafts up to fill the gap. Who discovered sea-floor spreading? The man who discovered sea floor spreading was Harry Hess. Harry Hess was a geologist. Part of his mission had been to study the deepest parts of the ocean floor. In 1946 he had discovered that hundreds of flat-topped mountains‚ perhaps sunken

Creation vs. Evolution Elisabeth Goldschmitt In the beginning there were no mountains‚ no dinosaurs‚ no caveman‚ no oceans‚ no sun‚ no stars‚ no time‚ and no space. There was only God.

Coastal Erosion- The beach moving due to storms‚ waves‚ tide currents‚ drainage and high wind. Strength of the wave can be more powerful if the waves is longer and the wind is stronger can create erosive power. . Sea Level Rise- Shrink land ice‚ such as ice sheets‚ and mountain glaciers.

The oceans are one of the most sacred places on this earth‚ the last mysterious frontier left. They hold millions of different marine animals‚ and many more that are waiting to be discovered. However‚ the wide blue waters are beginning to fade fast. Recently‚ a new pollutant has been exposed‚ carbon dioxide‚ is causing this acidification. Ocean acidification is when the saltwater absorbs enough carbon dioxide from the atmosphere that it changes the pH of the water. This is what is happening

The world was just a ball of ocean. It was the beginning of a beginning. Phoebgous was the creator of the world as we know it. Our planet earth took one million years to evolve into what it is. Phoebegous wanted to create a world of living creatures‚ he was very determined to make it work! So he inaugurates the world. He drops seeds in the ocean which slowly forms into islands and continents and conveniently creates all of our naturals. Like plants‚ mountains‚ ponds‚ etc. Though‚ there is a problem

deep ocean The oceans cover 75% of the world’s surface and contain 97% of its water; 90% of the seas lie beyond the shallow continental margins‚ and most are deeper than 2km. With the advent of modern science we have been able to discover what some of the deep ocean is like but there is still a vast area that remains unexplored. One thing we do know is that life at these depths is dominated by animals‚ not plants

The scientific realm of ocean trash and its impact has been left horrifyingly untouched and is only now being taken up. Consequentially‚ we have been oblivious to the negative affects of this issue to the point where (1) the largest landfill on Earth is situated in the Pacific Ocean‚ known as the Great Pacific Garbage Patch. Although we lack a proper understanding‚ it is still an enormous threat to our planet and to us as humans‚ a fact that we seem content to be ignorant of. Already‚ there are (2)

Discussion Section-1 November 17‚ 2011 The other CO₂ Problem Todays oceans are not the same as they once were prior to the industrial revolution. The ocean serves as a reservoir for the worlds green house gasses. The increase in anthropogenic CO₂ has also resulted in an increase in the uptake by the ocean of CO₂. As a result of this uptake‚ the ocean is becoming progressively more and more acidic. This acidification of the ocean is expected to have great impacts on marine ecosystems. Coral reefs
