Seismic Waves Plate Boundaries
1,198 words... dates. An example of the most well known and studied fault is the San Andreas Fault located of the coast of California. The origin of volcanoes: Hot spots, can be found on plate boundaries or inside the plates. The hot spot is a place deep inside the Earth that begins to form molten lava from extreme heat conditions. It will quickly rise up, pushing and melting its way to the surface resulting in a volcano. Because of the constant moving of the plates, the volcano will be carried away from t...

Seismic Sea Sea Floor Water
550 wordsA tsunami is a wave train, or series of waves, generated in a body of water. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis. These waves can savagely attack coastlines, causing devastating property damage and loss of life. In English, the word tsunami means "harbor wave. " Represented by two characters, the top character, "tsu, " means harbor, while the bottom character, "nami, " means "wave. " In the past,...

The End Permian Mass Extinction
3,006 wordsIntroduction Think of a world which existed 290 million years ago. As you look out over the trade in front of you, you think that you are on an alien planet. You see volcanoes spewing ash and lava. Beside them is the ocean which is swarming with many different species of echinoderms, bryozoans and brachiopods. As you look down onto the sea floor you are amazed at the countless number of starfish and urchins. Some animals leave you can't even describe and you have no idea even what phylum they be...

The End Permian Mass Extinction

Cosmic Radiation Global Cooling Global Warming Salinity The hypothesis that salinity decrease caused the mass extinction of oceanic life was first formed by Beurlen in 1956 (Maxwell, 1989). Evidence for this phenomena was based mainly on stenohaline groups such as the bryozoans, ostracods and corals which were...

Oceanic Crust Mid Ocean
1,629 wordster> Describe the frequency, origin and distribution of earthquakes at mid-ocean ridges, ocean basins, subduction zones and continental shields. Earthquakes are happening almost everyday all over the world. Most of the time earthquakes are not strong enough to be felt by people, but the shaking caused by an earthquake is recorded by a seismogram. These are located all over the world at different points. Only occasionally will a larger magnitude earthquake strike and cause damage to the...

Indian Ocean Pacific Ocean
1,327 wordsPlease note this is a "Scientific Report" not an essay please bare this in mind. Introduction The word Tsunami is a Japanese term meaning wave in the harbour. It is the most apt description for the hazard as tidal wave or seismic wave lead to incorrect connotations and misunderstandings. The dictionary definition of the word Tsunami itself means a very large ocean wave caused by an underwater earthquake or volcanic eruption, this is only half accurate, which I will attempt to illustrate in this ...

Sea Floor Bivalve D Brachiopods
284 wordsBrachiopods are Brachiopod Brachiopod Brachiopods are bivalve d marine invertebrates that constitute a separate group, Brachiopod. Brachiopods were prominent shell fish in many continental-shelf sea environments for about 250 million years, from the Ordovician into the Permian periods. In the Cambrian, some were prominent in nearshore environments. Since the end of the Paleozoic, clams appear to have been the prominent marine benthic bivalve d animal in environments previously inhabited by brach...

Stop Global Warming Carbon Dioxide
1,721 wordsEFTHIMIOS MARIAKAKIS The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absor...

Earths Surface Earths Crust
4,346 wordsEARTH The Earth, mans home, is a planet. The Earth has special characteristics, and these are important to man. It is the only planet known to have the right temperature and the right atmosphere to support the kind of environments and natural resources in which plants and man and other animals can survive. This fact is so important to man that he has developed a special science called ecology, which deals with the dependence of all living things will continue to survive on the planet. Many milli...

Earths Surface Ground Motion
851 wordsAn earthquake, one of the most destructive natural phenomena, consists of rapid vibrations of rock near the surface of the earth. It is the most terrifying of all natural phenomena and has brought fear since ancient times because of its sudden unpredictable occurrence and enormous capacity of destruction. A single shock usually last no more than a few seconds, although several quakes may last for as much as a couple of minutes. The quake as felt on the surface is always the result never the caus...

Shield Volcanoes Volcanic Activity
435 wordsKilauea Hawaii consists of a string of islands, or an archipelago. Kilauea is located on one of these islands, the central Hawaii island. Kilauea is one of the world? s most active volcanic craters. Craters are formed either by the massive collapse of material during volcanic activity, by unusually violent explosions, or later by erosion during dormancy (Compton's). It is situated on the southeastern slope of the great volcanic mountain Mauna Loa. Its elevation is 1111 m (3646 ft. ) above sea le...

Oceanic Crust Continental Drift
780 wordsPlate tectonics are a relatively new theory that has revolutionized the way geologists think about the Earth. According to the theory, the surface of the Earth is broken into large plates. The size and position of these plates change over time. The hypothesis of continental drift was largely developed by the German Alfred Wegener The edges of these plates, where they move against each other, are sites of intense geologic activity, such as earthquakes, volcanoes, and mountain building. Plate tect...
