What are the volcanoes in Auckland named? (Please specify)?
958956
Four major landmarks of Auckland volcanoes:\n\non Devonport peninsula: Mt Victoria and North Head, \nRangitoto Island, the youngest and highest of all Auckland's volcanoes, and Brown's Island. \n\nHowever, much of Auckland is built on a potentially active volcanic field. Within an area of about 360 square kilometres, there are approximately 50 volcanoes. None of these existing volcanoes are expected to erupt again. The next eruption will be in a new, unknown location.

Composite volcanoes/ strato volcanoe.\n\nSome of the Earth's grandest mountains are composite volcanoes--sometimes called stratovolcanoes. They are typically steep-sided, symmetrical cones of large dimension built of alternating layers of lava flows, volcanic ash, cinders, blocks, and bombs and may rise as much as 8,000 feet above their bases. Some of the most conspicuous and beautiful mountains in the world are composite volcanoes, including Mount Fuji in Japan, Mount Cotopaxi in Ecuador, Mount Shasta in California, Mount Hood in Oregon, and Mount St. Helens and Mount Rainier in Washington.\n\n\n**Here is a personal tip my teacher taught us..depending on the plate it's sitting on and the boundary you will know how the plates strike and collide ...in the case of helen think of yr two hands being forced together straight on max pressure eventually your fingers begin to cave and slide up ward together... it looks olmost pointy and cone shaped right? just like St. Helen... This is assuming you know about plates and faults ....Hopefully you do..if bot disregard..

Check out all the links I listed, you should enjoy...\n\nA volcano is an opening (or rupture) in the Earth's surface or crust, which allows hot, usually molten rock, ash, and gases to escape from deep below the surface. Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a period of time.\n\nVolcanoes are generally found where two to three tectonic plates pull apart or are coming together. A mid-oceanic ridge, like the Mid-Atlantic Ridge, has examples of volcanoes caused by "divergent tectonic plates" pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by "convergent tectonic plates" coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one another (like the San Andreas fault). Volcanoes can also form where there is stretching of the Earth's crust and where the crust grows thin (called "non-hotspot intraplate volcanism"), such as in the African Rift Valley or the European Rhine Graben with its Eifel volcanoes).\n\nFinally, volcanoes can be caused by "mantle plumes," so-called "hotspots;" these hotspots can occur far from plate boundaries, such as the Hawaiian Islands. Interestingly, hotspot volcanoes are also found elsewhere in the solar system, especially on rocky planets and moons.

The short answer is plate tectonics. Volcanoes can be divided into three major groups, those that are connected to a spreading center, like the mid-ocean ridges, those connected to a subduction zone, like Mt.St. Helens, or much of the Indonesian archipelago, and intraplate volcanism like Yellowstone. \n\nWhere the lithosphere (or crust) overlies an area within the asthenosphere (the layer of the earth under the crust) there are currents rising that cause volcanoes to form. These areas are called spreading centers. At the edges of the oceanic plates the plates often are forced under continental or even other oceanic plates. Where these plates are being forced downward, called subduction, there are volcanoes formed by melting magma rising from the descending plate. Most of the volcanoes around the edges of the Pacific Ocean are of this type, and are the reason it is called the "ring of fire".\n\nThe other group of volcanoes are related to what are called hot spots. These are places under the crust where the asthenosphere is especially hot. Yellowstone, and the Hawaiian Islands are examples of this. The hot spot under Hawaii is stationary, and as the Pacific plate has moved across it, it has produced a long chain of volcanic islands. \n\nYou can explore what makes volcanoes work at the following website sponsored by NASA:\nhttp://www.geology.sdsu.edu/how_volcanoes_work/Home.html

Shield volcanoes\n\nHawaii and Iceland are examples of places where volcanoes extrude huge quantities of lava that gradually build a wide mountain with a shield-like profile. Their lava flows are generally very hot and very fluid, contributing to long flows. The largest lava shield on Earth, Mauna Loa, rises over 9,000 m from the ocean floor, is 120 km in diameter and forms part of the Big Island of Hawaii. Olympus Mons is the largest shield volcano on Mars, and is the tallest mountain in the known solar system. Smaller versions of shield volcanoes include lava cones, and lava mounds.\n\nCinder cones\n\nVolcanic cones or cinder cones result from eruptions that throw out mostly small pieces of scoria and pyroclastics (both resemble cinders, hence the name of this volcano type) that build up around the vent. These can be relatively short-lived eruptions that produce a cone-shaped hill perhaps 30 to 400 m high. Most cinder cones erupt only once. Cinder cones may form as flank vents on larger volcanoes, or occur on their own. Paricutin in Mexico and Sunset Crater in Arizona are examples of cinder cones.\n\nStratovolcanoes\n\nThese are tall conical mountains composed of lava flows and other ejecta in alternate layers, the strata that give rise to the name. Stratovolcanoes are also known as composite volcanoes. Classic examples include Mt. Fuji in Japan, Mount Mayon in the Philippines, and Mount Vesuvius and Stromboli in Italy.\n\nSupervolcanoes\n\nSupervolcano is the popular term for large volcanoes that usually have a large caldera and can potentially produce devastation on an enormous, sometimes continental, scale. Such eruptions would be able to cause severe cooling of global temperatures for many years afterwards because of the huge volumes of sulfur and ash erupted that may block or partially block the sun. Examples include Yellowstone Caldera in Yellowstone National Park and Lake Toba in Sumatra, Indonesia. The Yellowstone volcano is the only dormant supervolcano in the world today. All the rest are long extinct. Supervolcanoes are hard to identify given their enormous areas covered. They are also known as flood basalt events due to the large amounts of basalt ejected.\n\nSubmarine volcanoes\n\nSubmarine volcanoes are common features on the ocean floor. Some are active and, in shallow water, disclose their presence by blasting steam and rocky debris high above the surface of the sea. Many others lie at such great depths that the tremendous weight of the water above them prevents the explosive release of steam and gases, although they can be detected by hydrophones and discoloration of water due to volcanic gases. Even large submarine eruptions may not disturb the ocean surface. Submarine volcanoes often form rather steep pillars and in due time, may break the ocean surface as new islands. Pillow lava is a common eruptive product of submarine volcanoes.\n\nSubglacial volcanoes\n\nSubglacial volcanoes develop underneath icecaps. They are made up of flat lava flows atop extensive pillow lavas and palagonite. When the icecap melts, the lavas on the top collapse leaving a flat-topped mountain. Then, the pillow lavas also collapse, giving an angle of 37.5 degrees. Very good examples of this can be seen in Iceland. These volcanoes are also called table volcanoes or mobergs.

Mauna Loa is a shield volcano, and as such it has comparatively gentle eruptions (as compared to stratovolcanoes, such as Mt. St. Helens.)  Shield volcanoes also produce high temperature low-viscosity basaltic lava, which contributes to the eruptions being gentle (except in the case of gas in the lava, which can cause fire fountains).\nMore information on shield volcanoes can be found here:\nhttp://en.wikipedia.org/wiki/Shield_volcano

Mt Tarawera (check your spelling) lies between the Mayor Island Fault Belt and the North Island Shear Belt. This fault system are fractures along the subduction zone formed by the Pacific Tectonic Plate and the continental crust upon which New Zealand is located. The subduction of the Pacific Plate with the continental crust generates the heat required for volcanic magma to form, and the two fault zones provide that heated material access to the surface.

There are and were other planets/moons that have volcanic activity.\n\nMars\nMars has the remnants of the largest volcano mountain.  The volcano would be the size of Arizona.  It is not active at the moment.  See the first link below for more information.\n\nIo - Moon\nThe recent Galileo trip to Jupiter revealed that its moon Io is very geologically active.  In its flyby back in 2000 it detected 10 new volcanoes.  81 volcanoes have been observed on Io.  See the second link for the CNN story.\n\nNevertheless, there are some other geologically active objects in our solar system.  There are certainly other objects that are active in the universe.

Geologists generally group volcanoes into four main kinds--cinder cones, composite volcanoes, shield volcanoes, and lava domes. \n\nIn regard to your question, Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most cinder cones have a bowl-shaped crater at the summit and rarely rise more than a thousand feet or so above their surroundings. Cinder cones are numerous in western North America as well as throughout other volcanic terrains of the world.\n\nShield volcanoes are built almost entirely of fluid lava flows. Flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that of a warrior's shield. They are built up slowly by the accretion of thousands of highly fluid lava flows called basalt lava that spread widely over great distances, and then cool as thin, gently dipping sheets. Lavas also commonly erupt from vents along fractures (rift zones) that develop on the flanks of the cone. Some of the largest volcanoes in the world are shield volcanoes. In northern California and Oregon, many shield volcanoes have diameters of 3 or 4 miles and heights of 1,500 to 2,000 feet. The Hawaiian Islands are composed of linear chains of these volcanoes including Kilauea and Mauna Loa on the island of Hawaii-- two of the world's most active volcanoes. The floor of the ocean is more than 15,000 feet deep at the bases of the islands. As Mauna Loa, the largest of the shield volcanoes (and also the world's largest active volcano), projects 13,677 feet above sea level, its top is over 28,000 feet above the deep ocean floor.
