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.

- Magma is a mixture of molten rock and gases below the surface of the Earth that may erupt from a volcano as lava.It may also cool and solidify below the surface. The rocks that form from magma are crystalline and fit into a general category called igneous rocks.agma often collects in magma chambers that may feed a volcano or solidify underground to form an intrusion. Magma is capable of intrusion into adjacent rocks (forming igneous dikes and sills), extrusion onto the surface as lava, and explosive ejection as tephra to form pyroclastic rock.

- 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.

Magma Lava is the extrusive equivalent of magma. Magma (from Greek μάγμα, thick unguent) is a mixture of molten or semi-molten rock, volatiles and solids that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets. Besides molten rock, magma may also contain suspended crystals, dissolved gas and sometimes gas bubbles.

Lava Explosive eruptions produce a mixture of volcanic ash and other fragments called tephra, rather than lava flows. The word lava comes from Italian, and is probably derived from the Latin word labes which means a fall or slide.

- Noun[edit] 1  A form of lava flow of basaltic rock, usually dark-colored with a smooth or ropey surface. It is one of two chief forms of lava flow emitted from volcanoes of the Hawaiian type, the other form being aa.  We [...] saw ‘pahoihoi’ or solid lava forming, and also ‘aa’ or clinkers.

Activity 3: Igneous Rocks The term igneous comes from the Latin ignis, meaning fire. Igneous is used to describe rocks that crystallize out of hot molten material in the Earth called magma. When magma pushes up through Earth's crust to the surface, it is called lava. Both magma and lava cool and harden to form igneous rocks.

How does magma become lava? The easiest way to define magma and lava: magma is molten rock that is still beneath the earth's crust. When magma reaches earth's surface, through a volcano or other openings in the earth's surface, it is still the same substance, but it is called lava.demonsheep87 · 9 years ago.y definition, magma becomes lava when it's erupted. When magma or lava cool, the minerals making up the molten soup begin crystallizing. The slower a magma cools, the larger its crystals grow.

Lava A lava fountain is a volcanic phenomenon in which lava is forcefully but non-explosively ejected from a crater, vent, or fissure. The highest lava fountains recorded were during the 1999 eruption of Mount Etna in Italy, which reached heights of 2,000 m (6,562 ft).

The floor is lava Hot lava (or the floor is lava) is a game, usually played by children, in which the players imagine that the floor or ground is made of lava (or any other lethal substance, such as acid or quicksand), and thus avoid touching the ground lest they get burned or otherwise injured.

- The truth is that Lava Rock is a a misunderstood name. Lava is molten(liquid) rock that comes out of an erupting volcano. It is extremely hot, reaching temperatures as high as 1,300 to 2,000 degrees.

Is lava a liquid or a solid? why? Most of the lava is in plasma state. Neither liquid nor solid. At very high temperature, electrons in outer orbit of any atom gain enough energy to get out of influential field of atom and become free electron. This is called process of ionization. Plasma is a state ionized state of matter.

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.illow lava is the lava structure typically formed when lava emerges from an underwater volcanic vent or subglacial volcano or a lava flow enters the ocean. However, pillow lava can also form when lava is erupted beneath thick glacial ice.

Magma: Definition & Formation Magma. Magma is defined as molten rock found below the earth's surface. It's a Greek word meaning 'thick ointment.' Why a geologist in the year 1859, which was the first known geological use of the word, decided that magma and ointment were similar is unknown.

Magma that is high in silica resists flowing, so expanding gases are trapped in it. Pressure builds up until the gases blast out in a violent, dangerous explosion.

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.his 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. When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 to 1,200 °C (1,292 to 2,192 °F).
