Lava Lava flow during a rift eruption at Krafla, Iceland in 1984. Lava is the molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. The source of the heat that melts the rock within the earth is geothermal energy.

- If the magma reaches the surface it is called lava and lava accumulates to make a volcano.   Volcanoes grow by intrusion and extrusion. An intrusion is magma that moves up into a volcano and then it stops, never erupting.This way the volcano grows on the inside. An extrusion is an eruption.It can add layers of lava or ash. This way the volcano grows on the outside.   Volcanoes erupt because of density and pressure. The lower density of the magma causes it to rise (like air bubbles in syrup).rash, greenhouse gases, almost anything. Unfortunately, humans cause pollution from cars and factories and etc..... exhaust, smoke, litter and cutting down trees. throw … ing household garbage, using old vehicles, smoking, using pesticides and insecticide Pollution is of various kinds, air, water, noise, etc.

- (Answer #4). Lava is made up of crystals, volcanic glass and bubbles (volcanic gases). When the magma gets closer to the surface and cool, it begins to crystallize minerals like olivine and form bubbles of volcanic gases.When the lava erupts, it is made up of crystals, liquid and bubbles.Answer #1). Lava is formed from “magma”, which is nothing but a very hot liquid (fluid or semi-fluid) that flows inside the Earth. When a volcano erupts, this magma comes out and reaches the Earth surface, cools down after contact with the atmosphere and finally becomes lava.

Volcano A close-up aerial view of the nested summit calderas and craters, along with the crater lake. A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Earth's volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. Therefore, on Earth, volcanoes are generally found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-oceanic ridge, such as the Mid-A

Lava A lava flow is a moving outpouring of lava, which is created during a non-explosive effusive eruption. When it has stopped moving, lava solidifies to form igneous rock. The term lava flow is commonly shortened to lava. Explosive eruptions produce a mixture of volcanic ash and other fragments called tephra, rather than lava flows.

- Lava is the name for magma that has reached the earth's surface. When lava comes to the surface, it is red hot and may have a temperature of more than 2012 F. (1100 C). Highly fluid lava flows rapidly down a volcano's slopes.Sticky lava flows more slowly.he beginning of a volcano. A volcano begins as magma, melted rock inside the earth, Magma results from the extreme heat of the earth's interior. The eruption of a volcano. The gas filled magma in the reservoir is under great pressure from the weight of the solid rock around it.

Volcanoes Volcanic eruptions. When a volcano erupts three types of material come to the surface: lava, small pieces of rock or ash, and gas. Magma that spreads out of a volcano slowly is called lava. It can reach temperatures of up to 1,200° C and glows red to white when it flows.In most cases, lava mixes with steam and gas.hen a volcano erupts hot gases and liquid rock come up to the surface from inside the earth. The material sometimes slides down mountains as lava or is hurled into the air as ash or small rocks. Volcanoes often destroy the land around them completely.

- Like your oil and water, the lava in a Lava Lite doesn't mix with the liquid that surrounds it. When it's cool, the lava is a little bit denser than the liquid surrounding it. When the lava rests on the bottom of the Lava Lite, the light bulb in the lamp warms it up. As it warms up, the lava expands a little.

- Everything in the path of an advancing lava flow will be knocked over, surrounded, buried, or ignited by the extremely hot temperature of lava. When lava erupts beneath a glacier or flows over snow and ice, meltwater from the ice and snow can result in far-reaching lahars.

Volcanoes About. Magma is liquid rock in between the crust and the mantle, formed when part of the lower crust or upper mantle melts. When magma travels up through a volcano’s vent, bubbles of gas also appear. All the gas builds up pressure, which causes the magma to explode out of the volcano. Many volcanoes are mountains, made up of layers of lava and ash. 2  Many volcanoes have several vents – a main one, and secondary ones that branch off the main vent. 3  The volcano’s main vent goes all the way down to the layer of magma in between the Earth’s crust and mantle.

What causes a volcano to erupt and how do scientists predict eruptions? Most recently, Professor Kilinc has been studying volcanoes in Hawaii and Montserrat. When a part of the earth's upper mantle or lower crust melts, magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged.OLTEN ROCK, or magma, and gasses spew from the mouth of a volcano in the Hawaiian islands. As rock inside the earth melts, its mass remains the same while its volume increases--producing a melt that is less dense than the surrounding rock.

Volcanoes Lava and Lava Flows. During most volcano eruptions, lava flows out of vents as a red stream of hot, molten rock. Its temperature is about 2000°F (1100°C). As it cools, the top of the lava becomes a silvery blue color, while the inside remains a brilliant red.

- The Hawaiian Islands are believed to be formed from one such 'hot spot'. As the plate moves away, the volcano stops erupting and a new one is formed in its place. With time, the volcanoes keep drifting westward and getting older relative to the one active volcano that is over the hot spot.ote that the islands of Lanai and Kahoolawe are not shown because they would overlap with Molokai and Maui, respectively (see the map of the Islands on the Hawaiian Volcanoes page) In general, when you move along the island chain from southeast (Hawaii) to northwest, (Kure), the volcanoes become older and older.

What is a Volcano? A volcano is vent or opening on planet’s surface which allows molten rock called magma, volcanic ash and gas to escape out onto its surface. A volcano gives a look like a mountain from which lava erupts.The hot magma erupting from a volcano is called lava.When that lava cools down, it becomes solid and forms like a mound-like cone. In fact the mountain that we see today are nothing but solidified lava from previous volcanic eruptions.It is said that through volcanoes are earth’s way of renewing itself.he hot magma erupting from a volcano is called lava.

- Cooler, more viscous and sticky lava (dacite or rhyolite) is much more reluctant to let the gases go; the result being that the pressure builds until released violently, like champagne from a shaken bottle. The gigantic eruption that destroyed Krakatau consisted of this latter type of lava, rhyolite.

As magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases. When lava erupts it is made up of a slush of crystals, liquid, and bubbles.The liquid “freezes” to form volcanic glass.

Magma and Lava 1 The faster the flow the slower the lava cools because the crust always wears out the slower the flow the faster lava makes its crust because it doesn t wear out the crust as much. 2  If a lava flow is to fast lava has to flow until it reaches land that is less steep.

- The most common type of volcanic eruption occurs when magma (the term for lava when it is below the Earth's surface) is released from a volcanic vent. Eruptions can be effusive, where lava flows like a thick, sticky liquid, or explosive, where fragmented lava explodes out of a vent.ere are some of the most common types of eruptions: In a Hawaiian eruption, fluid basaltic lava is thrown into the air in jets from a vent or line of vents (a fissure) at the summit or on the flank of a volcano. The jets can last for hours or even days, a phenomenon known as fire fountaining.
