What is "lava"

Lava \La"va\ (l[aum]"v[.a]; 277), n. [It. lava lava, orig. in Naples, a torrent of rain overflowing the streets, fr. It. & L. lavare to wash. See Lave.] The melted rock ejected by a volcano from its top or fissured sides. It flows out in streams sometimes miles in length. It also issues from fissures in the earth's surface, and forms beds covering many square miles, as in the Northwestern United States.

Note: Lavas are classed, according to their structure, as scoriaceous or cellular, glassy, stony, etc., and according to the material of which they consist, as doleritic, trachytic, etc.

Lava millstone, a hard and coarse basaltic millstone from the neighborhood of the Rhine.

Lava ware, a kind of cheap pottery made of iron slag cast into tiles, urns, table tops, etc., resembling lava in appearance.

1750, from Italian (Neapolitan or Calabrian dialect) lava "torrent, stream," traditionally from Latin lavare "to wash" (see lave). Originally applied in Italian to flash flood rivulets after downpours, then to streams of molten rock from Vesuvius. Alternative etymology is from Latin labes "a fall," from labi "to fall." Lava lamp is attested from 1965, also lava light (reg. U.S., 1968, as Lava Lite).

n. 1 The melted rock ejected by a volcano from its crater or fissured sides. 2 (context informal proscribed English) magma. 3 A shade of red, named after the volcanic lava.

n. rock that in its molten form (as magma) issues from volcanos; lava is what magma is called when it reaches the surface

Lava is molten volcanic rock or the resulting solid rock after cooling.

Lava may also refer to:

Lava is a color that is a shade of red. It is named after the color of volcanic lava.

This is the color (color #CF1020, shown at right) of fresh lava pouring out of a volcano.

The first recorded use of lava as a color name in English was in 1892.

Lava is a district of the City Municipality of Celje and a locality in the northwestern part of the city of Celje. Until 1982, Lava was an independent settlement.

Lava is a 2001 British black comedy directed by Joe Tucker.

The film competed at the Alexandria International Film Festival, Filmfest Oldenburg, Austin Film Festival and Rome Independent Film Festival in 2000.

Lava is a 1980 Indian Malayalam film, directed by Hariharan and produced by GP Balan. The film stars Prem Nazir, Jagathy Sreekumar, Prameela and Sathar in lead roles. The film had musical score by G. Devarajan.

Lava or Luv ( meaning "particle", Kannada: ಲವ, Telugu: లవుడు, Tamil: இலவன், Malay: Tilawi, Indonesian: Lawa, Khmer: Jupalaks, Lao: Phra Lao, Thai: Phra Lop) and his twin brother Kusha, were the children of Lord Rama and his wife Sita, whose story is recounted in the Hindu epic Ramayana. Kusha was the elder of the two and is said to have wheatish golden complexion like their mother, while Lava had blueish complexion like their father. Lava is purported to have founded Lavapuri, that is, the modern day city of Lahore, which is named after him. The Southeast Asian country Laos and the Thai city Lopburi were both named after him. The Sikarwar Rajputs, Awadhiya (caste) and Leva Patidar are present-day Indo-Aryan ethnic groups who claim to be descendants of Lava. Lava belongs to the Ikshvaku clan or Suryavansh Dynasty of Kshatriyas in ancient India.

Lava is a heavy-duty hand cleaner, originally produced in soap bar form, developed by the Waltke Company of St. Louis in 1893.

It is currently manufactured by the WD-40 Company, who acquired the brand from Block Drug in 1999, who acquired it from Procter & Gamble in 1995. Unlike typical hand soaps, Lava contains ground pumice, which gave the soap its name. The soap and pumice combination is intended to scour tar, engine grease, paint, dirt, grime, filth, and similar substances from the skin.

Lava soap is currently available in three forms, a red wrapper bar , a bulk count industrial green wrapper bar , and a liquid form (7.5 oz. pump bottle). The liquid form also contains moisturizers and recently the bar form added moisturizers into its formulation as well. The original Lava (without moisturizers), which was a beige bar, is no longer manufactured.

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 .

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. Although lava can be up to 100,000 times more viscous than water, lava can flow great distances before cooling and solidifying because of its thixotropic and shear thinning properties.

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. The first use in connection with extruded magma (molten rock below the Earth's surface) was apparently in a short account written by Francesco Serao on the eruption of Vesuvius between May 14 and June 4, 1737. Serao described "a flow of fiery lava" as an analogy to the flow of water and mud down the flanks of the volcano following heavy rain.

Lava (established 1977 in Årdal, Norway) is a Norwegian jazz-rock band, known from a series of recordings in the 1980s ( Polydor Records).

Lava is a 2014 computer-animated musical short film, produced by Pixar Animation Studios. Directed by James Ford Murphy and produced by Andrea Warren, it premiered at the Hiroshima International Animation Festival on June 14, 2014, and was theatrically released alongside Pixar's Inside Out on June 19, 2015.

The short is a musical love story that takes place over millions of years. It is set to a song written by Murphy, and was inspired by the "isolated beauty of tropical islands and the explosive allure of ocean volcanoes."

Lava is a 1985 Bollywood film starring Dimple Kapadia.

Lava is an experimental, visual object-oriented, interpreter-based programming language with an associated programming environment (Lava Programming Environment or LavaPE) that uses structure editors instead of text editors. Only comments, constants, and new identifiers may be entered as text.

Declarations are represented in LavaPE as tree structures whose subtrees may be collapsed or expanded. The properties of the declared Lava entities can be edited through pop-up dialogs.

Although executable code has a traditional text representation in LavaPE, it can be edited only as complete syntactic units, rather than character by character. If you insert a new syntactic construct, it will typically contain "placeholders" (syntactic variables) that can then be replaced by concrete constructs; the latter may in turn contain syntactic variables, etc. LavaPE provides a tool button for every type of syntactic construct, and a button is enabled only if it is syntactically correct to insert the associated construct at the selected place.

Further characteristic properties of Lava and LavaPE include the following:

• It provides strict syntactic separation of interface (public) and implementation (private) sections of a Lava class.
• It distinguishes variable "state objects" from constant "value objects"; the latter cannot be modified any longer after creation/initialization.
• It supports "virtual types": type parameters of classes and packages (families of related classes). As a consequence, undermining of strong type checks by "type casts" is no longer required.
• It uses recursion and logical quantifiers instead of traditional loop constructs.
• It uses single assignment; i.e., a value can be assigned to a variable only once within the same branch of a function.
• It supports refactoring extensively via the LavaPE structure editors.
• It distinguishes between constituents (sub-objects) and object acquaintances (pointers to independent objects). Copying and deletion of complex objects is largely facilitated in this way.
• Since release 0.9.0, LavaPE completely prevents inadvertent access to uninitialized variables and null objects already at programming time by complete static initialization checks.

Lava is open source software using the GPL license (see also Lava at the Free Software Foundation and at KDE-Apps.org). It currently runs on Microsoft Windows, Linux and Mac OS X platforms.
