Difference Between Lava and Magma Lava is also molten rock. When the magma that has been gathering under the earth’s crust comes out of a volcano, it is termed as Lava. There are different types of lavas that are classified according to their consistencies or viscosity. Lava that is thin can flow downhill for kilometers and makes a gentle flow or slope.

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. 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).

- Similarly, liquid magma also turns into a solid &#8212 a rock &#8212 when it is cooled. Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface.

- 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.

Is Lava a liquid? smart people only.? The molten rock that comes out of a volcano is called lava. When molten it is a liquid. When it hardens it is still lava, now in the solid form. Magma is the term used for lava when it is below the surface. 1. Molten rock that reaches the earth's surface through a volcano or fissure.

Lava Lava is the molten rock expelled by a volcano during an eruption. The resulting rock after solidification and cooling is also called lava. The 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 usually at temperatures from 700 to 1,200 °C (1,292 to 2,192 °F). A lava flow is a moving outpouring of lava, which is created during a non-explosive effusive eruption.

- Igneous Rock is formed when a magma cools underground and crystallizes or when it erupts unto the surface of the ground, cools and crystallizes. Magma that erupts onto the surface is called lava. When magma cools slowly underground the crystals are large enough to see.

- The inside of the Earth is very hot - hot enough to melt rocks. Molten (liquid) rock forms when rocks melt. The molten rock is called magma. When the magma cools and solidifies, a type of rock called igneous rock forms. What are they like? Igneous rocks contain randomly arranged interlocking crystals. The size of the crystals depends on how quickly the molten magma solidified. The more slowly the magma cools, the bigger the crystals. You may have done an experiment at school with a substance called salol. If molten salol cools slowly, you get big crystals. If it cools quickly, you get small crystals. Obsidian and basalt. If the magma cools quickly, small crystals form in the rock. This can happen if the magma erupts from a ...

When lava cools, which type of rock forms? I literally just searched on bing.com. This is what came up. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.

How Is Lava Created? While it’s fun to pretend, real hot lava is fairly easy to avoid, since it usually moves quite slowly. It is very hot, though. If you were to fall into hot lava, it would not be a pleasant experience. Your skin would be melted and burned by lava that can approach temperatures well over 2,000º F! Lava is molten rock. It is created deep beneath Earth’s surface (often 100 miles or more underground), where temperatures get hot enough to melt rock. Scientists call this molten rock magma when it’s underground.

Activity 3: Igneous Rocks 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.olidifying rocks at the surface cool too quickly for large crystals to form. Molecules in the lava do not have time to arrange themselves to form large crystals. Extrusive rocks have crystals that are too small to see without magnification. A common example of an extrusive igneous rock is basalt.

- (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.

When lava cools, which type of rock forms? Obsidian can be formed when lava cools on the surface and doesn't have enough time to crystalize. When lava cools on the surface of the earth it cools rapidly usually forming an extrusive rock...the most common extrusive rock being basalt. Hope that helps. Comments (1)

Lava 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 1. Molten rock that reaches the earth's surface through a volcano or fissure. 2. The rock formed by the cooling and solidifying of molten rock. [Italian, perhaps from Latin lābēs, fall, from Latin lābī, to fall.] Word History: Appropriately, lava was named by people living near Mount Vesuvius.

- Aa (pronounced “ah-ah”) lava is more solidified and flows sluggishly compared to its more fluid counterpart, pahoehoe. Aa consists of rough, jagged, uneven pieces that tumble forward and over each other as the flow moves down the slope.
