first though up by a man named Albert Wegener in 1912 but the idea of moving continents was not taking seriously until the 1960. This study is called plate tectonics‚ and it helps explain the continental drift‚ the spreading of the seafloor‚ why volcanoes erupt and how mountains are formed. The mountain range that runs from the northern tip of Alaska to the southern tip of South America were formed by the buckling of crustal rocks that crash into the edge of North and South America.

the coast of the Hawaii Island. It is 969 meters below the sea surface and 3‚500 meters above the ocean floor. 17. This new island is forming because the Pacific Plate is moving in a northwest direction‚ and as it moves toward the “hot spot”‚ new volcanoes will form‚ which makes Loihi the “new” volcano. 18. In Hawaiian‚ Loihi means long‚ which also describes the shape of this new island being long. It has two curving rift zones in both the north and the south summit‚ and has a caldera that is about

In the years since the wolf reintroduction‚ Yellowstone has become a premiere scientific laboratory for wilderness observation and ecosystem recovery. Scientists have come from around the world to watch the effect wild wolves have on the park. We have discovered that an ecological effect called the “trophic cascade” has taken over Yellowstone‚ with the wolves initiating a more natural ecosystem balance than has been seen in over sixty-five

INTRODUCTION: The Ring of fire (figure 1) is a horse shoe shaped fault line. This fault line is prone to Earth quakes and volcanic eruptions. The ring of fire Is home to 452 volcanoes and 75% of the worlds dormant and active volcanoes live on the Ring. PLATE TECTONICS Plate tectonics is a theory that the earth is split up in to different areas of the world. They glide on the mantle of the earth the plates act like a hard ridged shell (fig 2 plate tectonics) Some of the plate tectonics move very

The gray wolf is as adaptable as man; it is no wonder that the habitat of the gray wolf is spread all over the world. The Great Plains Wolf‚ which is a subspecies of the gray wolf‚ is a native to the gray wolf habitats in North America. It is also known as the buffalo wolf or the Eastern timber wolf. Once‚ these gray wolves dominated

Auckland Geological History * Nature of Auckland’s Volcanoes * Eruption History Volcanoes are an important feature of the Auckland city landscape. In most cases they are emphasized by their different forms such as reserves and parks‚ while in the other locations‚ they have been quarried away to meet the city’s demand for construction material. According to research‚ distributed over a 20km radius are approximately about 49 volcanoes in the Auckland region‚ this area is referred to as the

The Effects of Globalization on Labor Relations in the Auto Industry in the 80s and 90s Over the last several decades Labor relations within the United Auto Workers (UAW) and the automakers they are attached to have been a roller coaster ride. In the 1960’s and 1970’s the Union made substantial gains for its members in all aspects of bargaining. Wages were increased at levels unheard of today and they made huge improvements on health care and other fringe benefits. Membership was steadily

Phase 5 Individual Project The Sciences: Inquiry‚ Innovation and Invention SCI210-1202A-04 Professor Nicholas Kusina ToniAnn Santos Colorado Technical University May 15‚ 2012 Alfred Wegener first proposed the theory of “continental drift” in 1915 after finding evidence on continents that had drifted apart‚ matched very closely when the continents were brought together. Wegener also stated that the fossils found in a particular place often indicated of a possibility that the climate from

bombs dust‚ ash‚ lava and cinder are released into the air. Volcanic activity is classified by how often a volcano erupts. A volcano may be active‚ dormant‚ or extinct. Active volcanoes erupt constantly. Dormant volcanoes are inactive‚ but not long enough to determine whether they will erupt again or not. Extinct volcanoes have been inactive since the beginning of recorded history. Mount Etna is Europe’s highest and most active volcano. It is at least 500‚000 years old. It has had a series of volcanic

“Discuss the Extent to which volcanic and seismic activity are evidence for plate tectonic theory” (40) Plate tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which plates converge‚ diverge and move past each other. Alfred Wegener pioneered the theory of continental drift in the early 1900s which he supported
