VOLCANOES Mythology and Prophecy. The word 'volcano' comes from the little island of Vulcano in the Mediterranean Sea off Sicily. Centuries ago, the people living in this area believed that Vulcano was the chimney of the forge of Vulcan-the blacksmith of the Roman gods.

- Top definition. lava. Lava is molten rock that originated from the mantle of a planet. Usually extracted through volcanos either on land or underneath water. Not to be confused with magma, which is molten rock that is still under the planets surface. Magma turns into lava after it erupts onto the surface.

- And other craters are volcanic in origin. A volcano crater is a circular depression around a volcanic vent. This is where the lava, ash and rock erupt out of a volcano. In most situations, the volcano crater is located at the top of the volcano.

Volcano The word volcano is derived from the name of Vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn originates from Vulcan, the name of a god of fire in Roman mythology. The study of volcanoes is called volcanology, sometimes spelled vulcanology.

How do volcanoes create islands? A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot, molten rock, ash, and gases to escape from below the surface.Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a period of time. mid-oceanic ridge, for example 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.

Volcanoes A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth’s surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here.As a volcano erupts, it spills lava that flows downslope. volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth’s surface.

Glossary of geography terms A volcano is formed by eruptions of lava and ash. Volcanoes are usually cone shaped mountains or hills. When magma [magma: Magma is molten rock. ] reaches the Earth's surface it is called lava. When the lava cools, it forms rock. Volcanic eruptions can happen at destructive [destructive boundaries: The boundary of two plates which are moving towards each other.

- A volcano is an opening in the Earths surface through which lava, hot gasses, and rock fragments erupt. This kind of opening forms when melted rocks deep within the earth blasts through the surface.Most volcanoes are mountains, particularly cone-shaped one, are built up around the opening by lava and other materials thrown out during eruption.he lava gradually builds up a low, broad dome shaped mountain. The famous Mauna Loa in Hawaii is a shield volcano. Thousands of separate, over lapping lava flows, each less then 50 ft thick, formed Mauna Loa. This picture demonstrates the shield volcano.

Science 8A A volcano is a depositional mountain landform built up by the emission of hardened lava through a vent. The lava comes from a magma chamber deep underground. As the layers of hardened lava build up, the lava pours out from a crater at the top of the volcanic cone. 8.3-5 Name the three main types of volcanic emissions. Briefly describe or list the most common forms of each type.

Volcanoes When it reaches the surface, a volcano is formed. The magma flows out as lava, sometimes explosively. The majority of the world's volcanoes are associated with subduction zones. Since subduction zones represent plate margins, volcanoes tent to occur in lines, like the Cascade Range volcanoes or those on the Aleutian Peninsula. Once in a great while, a new volcano will form. This usually happens when an active underwater volcano produces enough lava to break the surface, such as Surtsey in Iceland in 1963.

Volcano Volcano. An opening or rupture in the earth’s surface through which lava, hot gases, and fragments of rock erupt. The effect of volcanic eruptions on humans is both direct—lava flow, tidal waves, mud slides—and indirect—releasing ash that affects the lungs or weather.

lava The Neapolitans who lived in the vicinity took the Italian word lava, meaning a stream caused suddenly by rain, and applied it to the streams of molten rock coming down the sides of Vesuvius. The term was then taken into Standard Italian, where it came to mean the rock in both its molten and its solidified states.

Volcano Myths and Rituals For example, in Africa, the volcano Oldonyo-Lengai, literally Mountain of God, is venerated by the Maasai as the giver of all good things. In gratitude for an eruption in 1917, young mothers went to the volcano and expressed their breast milk on the ground.

Volcano Volcanoes are closely associated with plate tectonic activity. Most volcanoes, such as those of Japan and Iceland, occur on the margins of the enormous solid rocky plates that make up the Earth’s surface. Other volcanoes, such as those of the Hawaiian Islands, occur in the middle of a plate, providing important evidence as to the direction and rate of plate motion.

- A volcano is a vent or chimney which transfers molten rock known as magma from depth to the Earth's surface.Magma erupting from a volcano is called lava and is the material which builds up the cone surrounding the vent. A volcano is active if it is erupting lava, releasing gas or generates seismic activity. volcano is a vent or chimney which transfers molten rock known as magma from depth to the Earth's surface.

How are volcanoes formed? Volcanoes are formed by upwelling of magma (hot molten rock) deep under the earth's surface. No one is quite sure why magma rises in certain areas, but when it does, it forms pockets which create pressure on the rock of the Earth's crust. volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface. Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface.

Volcanic Eruptions: What Causes Volcanoes to Erupt A volcano is basically a vent from which, magma, gases, and volcanic ash escape to the Earth's surface, through faults in the crust. They may erupt violently like Krakatoa in 1883, or just seep out lava like the Kilauea volcano.

Volcanoes A volcano is an opening in the earth's crust that allows molten rock from the mantle to flow out onto the surface as lava. Volcanoes also emit vast amounts of gas, primarily carbon dioxide, water vapor and sulfur dioxide.s the subducting plate plunges into the mantle, it becomes heated. When it reaches the asthenosphere or thereabouts, subducted water in the descending slab of crust lowers the melting temperature of the rock and a molten rock mixture forms. This hot, buoyant magma forces its way upward through the overriding crust.

- A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.he name volcano has its origin from the name of Vulcan, a god of fire in Roman mythology. As pressure in the molten rock builds up it needs to escape somewhere. So it forces its way up “ fissures ” which are narrow cracks in the earths crust. Once the magma erupts through the earth’s surface it’s called lava.
