Seafloor spreading

occur can save millions of lives, while also saving billions in public taxpayer funds to rebuild after the damage. There are several types of gravitational forces that occur within the earth and cause earthquakes, such as plate tectonics and seafloor spreading. Understanding these actions can allow us to have better understanding of the causation of earthquakes. Plate tectonics is the theory that states Earth’s outer shell is divided into several plates that glide over the rocky inner layer of…

Alfred Wegener was a german scientist who developed the theory of Continental drift. He believed all the continents were one land mass. He called this super continent “Pangea”. Wegener used evidence from three sources to support his theory. First, was fossil evidence from reptiles and plants. “Cynognathus” was a reptile that had fossils found on South Africa, and Africa. This is only possible because of continental drift, the animal couldn't have swam across a whole ocean. The next reptile is…

karen Plate Tectonics There are two main ways scientist learn of earth saunterer is rock samples are rock sample from looking at the rock that comes from defence babanic explosion. The second main ways selected learn about earth centered is seismic waves seismic waves inderal travel thpro put where they travel speed path. Inconclusive this is how scientists learn about earth…

There are many different aspects in the world of geology. Something that I want to focus on are hydrothermal vents. Hydrothermal vents are like chimney shaped hot springs that are located on the ocean floor. Hydrothermal vents were first discovered in 1977 near the Galapagos Islands in the eastern Pacific. Scientists exploring the area along the mid-oceanic ridge had noticed drastic temperature changes in their data. With the help of ALVIN, a research deep sea submersible, they discovered vents…

Primordial Soup Hypothesis: The scientist involved in the hypothesis was A.I. Oparin and J.B.S. Haldane. The year the hypothesis was presented was in 1920. The claim of the scientist was that life began in a pond or ocean and chemicals in the atmosphere mixed to form all the the species today. The evidence that was presented to the scientist was that the first organisms were autotrophs. The experiments the scientist did was they mixed methane, ammonia, water , hydrogen , and not oxygen. The…

What if people were fish and someone put oil in our homes? When the oil went into the water, all the fish and other sea creature’s home were ruined. Does the Gulf oil spill affect humanity? Is the Gulf oil spill harmful to the water that we drink today? The Gulf coast, marine life, and human communities were all affected by the oil spill. To people who experienced the oil spill, they know that it is one of the most tragic oil spills in the history of the United States. There were cameras…

tectonics describing the ways the tectonic plates interact and the result of their interactions. The Continental Drift Theory The Continental Drift can help the surface support the current by plowing through ocean basins. It also did not include seafloor spreading or subduction. So, that did not cause an earthquake because it would not support it if it did have an earthquake, because it would shake it. The seismic data discovered that there are zones of Earthquakes that dip down deep. The new…

already leaked into the Gulf, noting this to be the worst oil spill to occur in the U.S. history. The oil spread throughout the water with some hovering on the surface forming oil slicks or in midwater. Some of the other bulk of oil ended up on the seafloor which damaged the sea corals. With that…

this: 141 million years ago, during the Cretaceous Period, western North America from the Arctic to the Gulf of Mexico was covered by a shallow sea that some geologists have dubbed the Western Interior Seaway. Dead marine organisms rained down on the seafloor, forming thick sediments that ultimately became the Pierre Shale, one of the sedimentary rock layers that the American Rockies punched up…

underwater mountain system that consists of various mountain chains, typically having a valley known as a rift which is formed by plate tectonics. This type of oceanic ridge is a characteristic of what is known as the oceanic spreading center that is responsible for seafloor spreading. (Geonature) The seas surrounding Greece are the Ionian Sea, the Mediterranean Sea, the Sea of Crete, the Thracian sea, and the Aegean Sea. The Aegean Sea and the Ionian Sea are the most commonly…
