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...

Thousands Of People Wind
385 wordsWind is one of the most destructive forces of our environment. Just recently we have seen the effects of two massive hurricanes in Florida of the United States. Houses torn down, uprooted trees and smashed cars are just some of the damage these two caused. Lives have also been lost due to these roaring monsters and theres a third brewing again. Theres also tornadoes, also known as twisters, which also occur frequently in the US. The aftermath of them is basically the same except for the face tha...

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...

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 ...

Million Years Ago Continental Drift
498 wordsThe earth, from its deep majestic oceans to its breathtaking mountains, is our home. But what goes undetected to humans is the violent cycle that is going on underneath our earth at this very moment. Volcanoes are spouting hot magma. Earthquakes are destroying cities and the continents we live on are moving around the ocean. But why do these phenomenon occur and what causes them to happen? From space the earth may look like one large floating mass. But underneath all of the oceans and continents...

Tectonic Plates Oceanic Crust
1,370 wordsThe core is divided into two parts, the solid inner core and the liquid outer core. The inner core is thought to be solid and primarily made up of iron and some nickel. The outer core is all around the inner core and is believed to be made up of liquid iron mixed with liquid nickel. The outer core is about 2890 to 5100 km. The inner core is 5100 to 6378 km. Earths mantle is mainly composed of substances high in iron and magnesium. The melting point of every substance depends on the pressure and ...

Tectonic Plates Molten Rock
689 wordsIn 1912, Alfred Wegener, a German scientist, was the first to notice this and develop the theory of plate tectonics. He noticed that the earth's continents fit together almost like a jigsaw puzzle. This, combined with the fact that similar fossils and rock types are found on different continents separated by large bodies of water, helped him formulate his conjecture. He contended that the plates at one point formed one large continent called Pangea, which allowed like fossils and rock types to b...

Upper Saddle River Prentice Hall
888 wordsThe Earth is often referred to as the blue planet since it is seventy-one percent oceans and marginal seas with only twenty-nine percent comprising the continents and islands. There are three principal topographic features of the planets ocean floor: continental margin, ocean basin floor and mid-ocean ridge. The continental margin is the most extensive feature of the ocean floor divided into two kinds: a. ) the active continental margins which are primarily located around the Pacific Ocean with ...

Oceanic Crust Ocean Basins
1,875 wordsThe Cordilleran Orogeny The earths lithosphere can be divided into two major structural features: ocean basins and continents. Ocean basins, as we discussed in another essay, are formed at spreading ridges and consumed at subduction zones. The continents are a different story. How did the continents originate, and how have they changed over time? The origin of the earliest continental crust is still relatively obscure, but the evolution of the continents over time is not: the continents have cle...

Contemporary Aboriginal Art References Web Web Web Dreaming
773 wordsOceanic art is diverse in style and technique. Artefacts were not considered art by their creators, but were an integral part of the religious and social ceremony of everyday island life. Art objects include ancestor figures, canoe-prow ornaments, ceremonial shields, masks, stone carvings, decorated human skulls, pottery, and stools. Fertility is a recurrent theme, along with occasional references to headhunting and ritual cannibalism. Most Oceanic arts are considered primitive in that until rec...

Today, volcanoes are a well-explored natural occurrence and theres even a science, called volcanology, which investigates this phenome...

Environmental Protection Agency Ozone Depletion
1,137 wordsThe ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases. 1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on...

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...

Plate Tectonics Ocean Basins
530 wordsPlate Tectonics is theory of global tectonics (geologic structural deformations) that has served as a master key in modern geology for understanding the structure, history, and dynamics of the earths crust. The theory is based on the observation that the earths solid crust is broken up into about a dozen semirigid plates. The boundaries of these plates are zones of tectonic activity, where earthquakes and volcanic eruptions tend to occur. Plate Tectonics also are the cause of major features that...
