Beneath The Surface Mauna Loa
1,512 wordsWhich are the biggest (tallest and largest volume) and smallest volcanoes on Earth? The island of Hawaii is probably the largest volcano on earth. From its base (on the floor of the Pacific Ocean) to the summit of Mauna Kea (about 13 000 ft) is some 30 000 ft i. e. higher than Everest. The island comprises several coalescing volcanoes including Mauna Loa, Mauna Kea and Kilauea. Mauna Loa alone has an estimated volume of 40 000 km 3. It is impossible to say which is the smallest volcano since the...

Mauna Loa Carbon Dioxide
1,498 words... locked into the melted minerals. If volcanic rocks erupt on the earth's crust, such as the Andean volcanoes, then magma can interact with carbonate rocks such as chalk as it travels up through the mantle or lower crust, picking up carbon dioxide on the way. In subduction zones, where the ocean floor goes down into the mantle some carbonate rocks do get taken down and melted, recycling their carbon dioxide content, but this is a minor source compared with the mantle. Carbon is quite common de...

Sodium Chloride Earth Crust
745 wordsSodium has an atomic number of 11 and a mass of about 23 g. It is a silvery white-metallic element classified under the alkali metals. Sodium has been known since early times and was used by the people of Mesopotamia and Egypt to make glasses. Sodium is the sixth most common element found on the earth. It is usually not found in nature but more often in compounds such as salt (NaCl). Sodium conducts heat and electricity easily. Without this element life could not exist. Each compound is used for...

Creation Of Steel Bessemer Converters Iron
678 wordsScience, technology and natural resources, were the driving force behind the Industrial Revolution in the United States. The telephone, the new steel, railroads and electricity in general led to the shift from a rural country to a technological and industrial America. Because of many inconveniences that were posed upon the American people during the 1800 's, such as impractical farming techniques, ample communication, and poor transportation resources, caused great minds and inventors to come to...

Earth Crust Molten Rock
372 wordsHow Are Mountains Formed? Mountains are formed over long periods of time by forces of the earth. Mountains just don't appear in any place. Most are formed when plates, or huge pieces of the Earth's crust, pull and push against each other. Great mountain ranges are formed by the movement of tectonic plates. Convection currents deep in the mantle of the earth, begins to well up towards the surface. As the pressure increases, it sets the crustal plates in motion. There are different kinds of mounta...

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...

Gas And Dust Nuclear Fusion
991 wordsAn Introduction to World History. "Any scientist, I think, will agree that in a hundred years time, many of the details of the story we tell now may look kind of cute and naive, because well have moved on beyond them. But if you happen to live now, " he concludes, "this is the best story going. " said David Christians and it is really true. We lived in a beautiful world but dont know a lot about cosmology, geology, archeology, and population and environmental studies. Today with the help of Davi...

Molten Rock Degrees F
715 wordsMy Journey to Iceland During my journey to Iceland, I have seen a natural event that made that journey very important to me. In southeastern Iceland, some 4, 500 feet above sea level, lies Vatnajokull -- the largest temperate-zone ice cap in Europe. Vatnajokull, 3, 200 frozen square miles overlying Iceland's most active volcanic region, sits, as does the rest of the island, above a mantle plume -- a column of hot rock that rises from the depths of Earth and feeds volcanoes with lava. Although it...

16 Th Century 15 Th Century
1,153 wordsWrought-iron breechloaders Gun military technology Wrought-iron breechloader's Partly because of the difficulties of making a long, continuous barrel, and partly because of the relative ease of loading a powder charge into a short breechblock, gunsmiths soon learned to make cannon in which the barrel and powder chamber were separate. Since the charge and projectile were loaded into the rear of the barrel, these were called breechloader's. The breechblock was mated to the barrel by means of a rec...

Earths Rotation Solar Wind
1,404 wordsTHE MOON Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies. The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moons phases. The time between successive new moons is 29. 5 days (709 hours), slightly different from the Moons orbital pe...

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...

2,015 wordsThe Mercury Report Mercury Report The magnificent planet Mercury is the planet I have chosen to research. I this report I have explained all there is to know about Mercury and its aura. The Romans gave Mercury its name after the fleet-footed messenger of the gods because it seemed to move quicker than any other planet. It is the closest planet to the Sun, and second smallest planet in the solar system. Its diameter is 40 % smaller than Earth and 40 % larger than the Moon. It is even smaller than...
