short essay on volcanoes Short Essay on Volcanoes. Article shared by. A volcano is an opening, in the planet’s surface which allows hot, molten rock, ash and gases to escape from below the surface. The name, “volcano” originates from the name Vulcan, a god of fire in Roman mythology. Volcanoes are like giant safety valves that release the pressure that builds up inside the Earth. The Hawaii islands were formed by 5 volcanoes. Classified by the extent of their activity volcanoes are of four types. An ‘active’ volcano is one that erupts regularly.  A volcanic eruption occurs when hot rocks and lava burst from a volcano; and geysers and springs are actually just volcanoes that throw boiling water high in the air. They are caused by volcanic heat warming trapped ground water. A volcano is an opening, in the planet's surface which allows hot, molten rock, ash and gases to escape from below the surface. The name, "volcano" originates from the name Vulcan, a god of fire in Roman mythology. Basing on the mode of eruption volcanoes are classified as: (i) Central types, where the products escape through a single pipe (or vent). (ii)Fissure types, where the ejection of lava takes place from a long fissure or a group of parallel or closed fissures. Basing on the nature of eruption, volcanoes may be of two types as: (a) Explosive Type: In which case the lava is of acidic (felsic) in nature and because of their high degree of viscosity, they produce explosive eruptions.  Short essay on Climatic Factors in Summer Season in India.

Of course, we no longer short essay on volcanoes this is true. The magma is heavily charged with gases such as carbon dioxide, short essay on volcanoes hydrogen, vllcanoes small proportions of nitrogen, chlorine and other volatile substances. The gases and vapour increase the mobility and explosiveness of the lavas which are emitted through the orifice or vent short essay on volcanoes a no during a volcanic eruption.

There are two main types of lavas.

They are dark coloured like basalt, rich in iron and magnesium but poor in silica. As they are short essay on volcanoes out of the volcano, they flow quietly and are not very shrt.

Due to short essay on volcanoes high fluidity, they flow readily with a speed of 10 to 30 miles per hour. They affect extensive areas, spreading out as thin sheets over great distances before they solidify. The resultant volcano is gently sloping with a wide diameter and forms a flattened shield or dome Fig.

These lavas are highly viscous with a high melting point. They are light-coloured, of low density, and have a high percentage of silica.

Lava, of low viscosity, flows easily through this type of volcano. The constant flow of the fluid basaltic lava, from the fissures on its surface, gives rise to the build up of a huge volcanic mountain.

They flow slowly and seldom travel far before solidifying. The resultant cone is therefore steep- sided. The rapid congealing of lava in short essay short essay on volcanoes volcanoes vent obstructs the flow of short essay on volcanoes out-pouring lava, resulting in loud explosions, throwing out many volcanic bombs or pyroclasts Fig.

An ‘active’ volcano is one that erupts regularly.  A volcanic eruption occurs when hot rocks and lava burst from a volcano; and geysers and springs are actually just volcanoes that throw boiling water high in the air. They are caused by volcanic heat warming trapped ground water.

Those that have been known to erupt and show signs of possible eruption in the future are described as dormant. Volcanoes that have not erupted at all in historic times but retain the features of volcanoes are termed extinct.

All volcanoes essqy through active, dormant and extinct stages but we can never be thoroughly sure when they are extinct. Krakatau were once thought by people to be extinct and yet both erupted most violently. Solid, liquid or gaseous materials may find volcaoes way to the surface from some deep- seated reservoir beneath. Short essay on volcanoes magma is mobile rock that forces its way into the planes of weakness of the crust to escape quietly or explosively to the surface.

The resultant landforms depend on the strength and fluidity of the magma, the types of cracks, faults and joints that it penetrates, and the manner volcwnoes which it escapes to the ob. Magma shorrt thrusting essay planning palgrave your way up to suort essay on volcanoes surface may cool and solidify within the crust as plutonic rocks resulting in intrusive landforms.

Short essay on volcanoes formed short essay on volcanoes either sssay or volcanic activity are called igneous rocks. Perhaps the commonest intrusive landforms are sills and dykes. When an intrusion of molten magma is made horizontally along- the bedding planes of sedimentary rocks, the resultant intrusion is hsort a sill.

Denudation short essay on volcanoes the overlying volcaboes strata will expose the intrusion which will resemble a check this out flow, or form a in escarpment like the Great Whin Sill of N. Because of their narrowness, dykes seldom dominate the landscape. When exposed volcajoes denudation they may appear as upstanding walls short essay on volcanoes shallow trenches, depending on whether they volcanoew more or less resistant than the rocks in which they are emplaced.

A large, very resistant in of quartzite forms a long ridge to the north of Kuala Lumpur. A laccolith is a large blister or igneous mound with a dome-shaped upper surface and a level base fed by a pipe-like conduit from below.

It arches up the overlying strata of volcanoed rocks, e. A lopolith is another variety of igneous intrusion with a short essay on volcanoes shape. A shallow basin vplcanoes formed in the midst of the country rocks.

The Bushveld lopoliths of Transvaal, South Africa are good examples. A phacolith is a lens-shaped mass of igneous rocks occupying the crest of an anticline short essay on volcanoes the bottom of a syncline and being esay by a conduit from beneath. An example of a phacolith is Corndon Hill in Shropshire, England. A batholith is a short essay on volcanoes mass of igneous rocks, usually granite, which after removal of the short essay esay volcanoes shorf forms shirt massive and resistant upland region such as the Wicklow Mountains short essay on volcanoes Ireland, the uplands of Brittany, France short essay on volcanoes the Main Range of West Malaysia.

Their precise mode of origin is still a matter of controversy. These metamorphosed rocks together with the solidified magma give rise to extensive batholiths, sometimes hundreds of miles in extent. They are the most spectacular of the intrusive landforms. Extrusive landforms are determined by the nature and composition of the lava and other ejected materials that reach the surface of the earth.

The fluid basic lava, flowing for long distances produces extensive lava plains and basalt plateaux, such as the great lava plains of the Snake Basin, U. The basalt plateaux are found in many continents, e. Volcanic cones are most typical of the extrusive features. The highly fluid lavas build up lava domes or shield volcanoes with gently rising slopes and broad, flattened tops.

The volcanoes of Hawaii have the volcznoes developed lava domes. The spectacular Mauna Loa and Kilauea are so accessible that they have been closely studied. Kilauea has a very steep-walled caldera into which the active vent pours red hot lava forming the lava-pit of Halemaumau.

Thousands of lava fountains rise and fall in the dazzling shprt. The less fluid lavas that explode more violently form ash and cinder cones with large http://ogneupor.info/13/k-38.php craters shory steep slopes.

They are typical of small volcanoes, occurring in groups and seldom exceeding 1, feet in height, such as Mt. Nuovo, near Naples and Mt. The lava flows are http://ogneupor.info/12/i-23.php viscous that they solidify after a short distance. Short essay on volcanoes more info are confined in valleys, they form lava tongues and lava-dammed lakes when they dam a short essay on volcanoes valley.

"It is said that there are almost active volcanoes in the Philippines, 40 in the Andes, 35 in Japan, and more than 70 in Indonesia. Volcanic materials are thrown up to greater height in the sky. Supervolcanoes are hard to identify centuries later, given the enormous areas they cover. These features are formed due to both quiet as well as explosive volcanic activity, and some of which are as follows: A laccolith is a large blister or igneous mound with a dome-shaped upper surface and a level base fed by a pipe-like conduit from below. Volcanoes are said to be active when they frequently erupt or at least when they have erupted within recent time."

Other minor features that may be associated with lava obstructions include lava bridges and lava tunnels. A volcanic region may be strewn with solid materials that were hurled from the vent of the volcano. The very fine particles are the volcanic dust which may be shot so high into the short essay on volcanoes that it travels round the world several times before it short essay on volcanoes comes to rest.

The shrot fragmental rocks are collectively called pyroclasts and include cinders short essay on volcanoes lapilli, scoria, this pearl harbor essay thesis talk and volcanic bombs. The highest volcanpes most short essay on volcanoes volcanoes have composite cones. They are often called strato- volcanoes. Each new eruption sohrt new layers of ashes or lava to the sides of the volcano, which grows steadily in height.

From the short essay on volcanoes conduit, subsidiary dykes or pipes may colcanoes the surface as feeders to parasitic cones.

Lava escapes through them to the sides of the main essau Fig. Etna in Sicily has husdreds of such parasitic cones.

Another interesting onn volcano is Mt. Popacata- petl and Mt. During an eruption material from the top of the cone is blown off or collapses into the volacnoes widening the orifice into a short essay on volcanoes crater. Some volcanoes may have greatly enlarged depressions called calderas, which may be several miles across. These are the result of violent eruptions accompanied by the subsidence of much of the volcano into the magma o Fig.

Water may collect in the crater volcanoea the caldera forming crater or caldera lakes, e. Lake Toba in Sumatra. In the history of mankind perhaps the most disastrous eruptions were those of Mt. Vesuvius, standing 4, feet above the Bay of Naples, erupted violently on 24 Volcanies a. White-hot lava flowed from parasitic cones. In the midst of a thundering explosion, the highly gaseous magma escaped as short essay on volcanoes luminous clouds in cauliflower form and shot up to great heights before it fell to earth as pyroclasts and ashes.

The ovlcanoes of Pompeii, located to the south-west, was buried beneath twenty feet of volcanic ashes which were later cemented by the torrential downpours of heavy rain that more info the violent eruption. In a similar way, the city short essay on volcanoes Herculaneum on the west was completely overwhelmed short essay on volcanoes short essay on volcanoes mudflow of ashes and cinders link 50 short essay on volcanoes thick, washed down by torrential rain from the slopes of Vesuvius.

Almost the entire population of the two cities was buried alive. After this, minor eruptions occurred from time to time but the fertility of the solidified Volcanic ashes tempted many farmers to begin anew on the slopes of Vesuvius. Then came the catastrophic eruption of December when an avalanche comprising red hot volcanic debris, pasty lava and highly energized gases ruined fifteen towns and killed 4, inhabitants.

The ashes that descended on Go here were estimated to be a foot thick. The greatest volcanic shorf known to men is perhaps that of Esday. Krakatau in August Krakatau is a small volcanic island in the Sunda Straits, midway between Java and Sumatra.

Dense black clouds of ashes shot 20 to 50 miles high, and were brought down as mud by the torrential rain which fell over the adjacent islands. So much magma was ejected from the underlying reservoir that two- thirds of the island shprt and disappeared forming a huge submarine caldera.

The explosion could be heard in Australia, almost 3, miles away.
