Lava is the word for magma (molten rock) when it erupts onto the Earth's surface. Geologists also use the word to describe the solidified deposits of lava flows and fragments hurled into the air by explosive eruptions (for example, lava bombs or blocks). Lava is from the Italian word for stream, which is derived from the verb lavare--to wash.
A volcanic rock protruded by the eruption of molten material.
hot liquid rock that flows out of a volcanic vent.
It is the name given to molten rock on earth's surface that is released from a volcano.
Molten, fluid rock that is extruded onto the surface of the Earth through a volcano or fissure. Also the solid rock formed when the lava has cooled.
A general term applied to igneous rocks such as basalt and rhyolite, that erupted from the earth by volcanic action.
Rock from a volcano, generally molten when ejected.

magma that has streamed out from the crust into the earth's surface.
when molten rock reaches the earth's surface, it is called lava
rock that in its molten form (as magma) issues from volcanos; lava is what magma is called when it reaches the surface
Magma or molten rock which reaches the Earth's surface exposed to air or water. Lava occurs as flows, domes, fragments within cones of volcanoes and as pillows formed on the ocean floor.
_Molten rock reaching the earth's surface where it rapidly cools. Fine grained.
Molten rock that is erupted onto the surface of a planet and is hot enough to flow.
A general term for rock that has solidified from molten material extruded on the surface of the earth.
the molten silicates or the congealed rock that issues onto the surface of the earth.
Once the magma reaches the Earth's surface and is extruded, it is known as "lava".
Molten rock that erupts to Earth's surface through a volcano or a fissure.
Partially molten rock that has risen through Earth's crust and been erupted onto the surface.
Melted magma from beneath the earth's crust which is forced up through cracks and pours forth from volcanoes
Magma which has reached the surface through a volcanic eruption. The term is most commonly applied to streams of liquid rock that flow from a crater or fissure. It also refers to cooled and solidified rock.
A bonsai soil amendment formed from crushed volcanic ash.
Magma that reaches the Earth's surface through a volcanic eruption. When cooled and solidified, forms extrusive (volcanic) igneous rock.
molten rock that erupts from a fissure or a vent (see magma).
Molten rock that erupts from a vent or fissure; see magma.
Molten rock (magma) that extrudes through a volcano
fluid (molten) rock that issues from a volcano or fissure.
Molten rock that erupts onto Earth's surface.
Magma that has come in contact with the air, (only the mane changes to lava, not the make-up) and flows on the earth’s surface.
molten magma extruded from volcanic vent
Molten rock that flows over the surface of a volcano as a very dense fluid and solidifies to form a hard, dense rock.
Magma or molten rock that has reached the Earth's surface.
Molten rock after it has erupted from a volcano onto the Earth's surface.
The rock mass formed by consolidation of molten rock issuing from volcanic vents and fissures.
The term used for magma once it has erupted onto the Earth's surface.
Molten rock erupted onto the surface of the Earth. Lavas vary according to the chemistry of the molten rock. In general the more silica they contain, the more viscous they are. Basalt, a silica-poor ( basic) lava tends to flow easily and therefore form thin, extensive lava flows, while rhyolite lava ( acid) is so viscous it rarely flows and forms ' domes' above the site of the eruption.
Molten rock that has flowed out onto the Earth's surface.
Magma that flows from the earth's surface.
Lava is molten rock. It usually comes out of erupting volcanoes.
molten rock above a planet's surface.
Molten rock erupted from a volcano. Lava can occur in flows, domes, fragments and as pillows formed underwater.
the term for magma which has reached the Earth's surface and lost its dissolved gas content.
magma Melted, glowing rock, which flows the surface on the occasion of eruptions.
Molten rock that forms above the surface of the Earth as a result of volcanic activity.
Any molten material that is extrusive or volcanic, or the rock that forms from a molten extrusive.
molten rock that reaches the earth's surface through a volcano or fissure, often referred to in the form of lava flows - BACK
molten matter more ( acidic lava) or less ( basic lava) viscous, pour out from volcanoes; concern also consolidated rocks : lava flow.
magma which has erupted onto the Earth's surface.
molten rock that flows onto the surface from a volcano or fissure.
molten magma that has reached the Earth's surface.
molten rock that flows out onto the Earth's surface
formations resulting from the consolidation of molten rock on the surface of the Earth (kepula, lava flow).
Melted, or molten, rock is called magma if it is below the earth's surface, and lava if it reaches the earth's surface.
the red-hot molten rock materials violently or quietly extruded by a volcano. Lava is the term applied to magma when it finally reaches the earth's surface.
Molten rock that has reached the surface; also hardened volcanic rock. Beneath the surface, the molten rock is called magma.
Molten rock material that has extruded onto the Earth's surface.
Once magma gets to earth's surface and extrudes it can be called lava. Below ground it is always called magma.
Molten rock with has poured out at the surface of the earth.
Molten rock erupted from volcanoes. See also Magma.
Magma that reaches the surface; molten material that is thrown out or has flowed from a volcano. Material that has reached the surface and solidified is also known as lava.
A general term for molten rock that is extruded onto the surface.
Magma which reaches the surface of the earth.
Molten rock that is extruded (forced out) from a volcano.
Magma which has, or is coming out of a volcanic crater or fissure.
the molten rock flowing from a volcano or fissure in the earth; the rock formed by the cooling of this molten rock.l Some lavas are dense and glassly or crystalline, others are light and porous. [AHDOS
A general term for a molten extrusive; also, for the rock that is solidified from it.
Molten rock at or near the surface of the earth that becomes igneousrock. Below the surface, lava is known as magma.
Lava is molten rock expelled by a volcano during an eruption. Magma is molten rock below the earth's surface. Lava, when first exuded from a volcanic vent, is a liquid at temperatures from 700 °C to 1,200 °C (1,300 °F to 2,200 °F).
Lava is a rock-based experimental band hailing from Spain. The band is known for its complex, varied, and often cathartic musical arrangements, heavily influenced by pop, post-rock, folk, and traditional Spanish music. Some of the band members also work in other projects.
