The word lava comes from Italian and is probably derived from the Latin word labes, which means a fall or slide. [2] [3] An early use of the word in connection with extrusion of magma from below the surface is found in a short account of the 1737 eruption of Vesuvius, written by Francesco Serao, who described "a flow of fiery lava" as an analogy to the flow of water and mud down the flanks of ...
The word 'malpaís' in Spanish translates to "badland," and this describes the area as being extremely rough and difficult to traverse and unusable for crops.Although a malpaís is often another word for the badlands that form by erosion of sedimentary rocks in the same environment, a malpaís is often associated with such types of lava plain terrain as found in a volcanic field.
Lava lake – Molten lava contained in a volcanic crater; Lava field, also known as lava plain – Large, mostly flat area of lava flows; Lava spine – Vertical growth of solid volcanic lava; Lava tube – Natural conduit through which lava flows beneath the solid surface; Lavaka – Type of gully, formed via groundwater sapping
The Kaʻū Desert is a leeward desert in the district of Kaʻū, the southernmost district on the Big Island of Hawaii, and is made up mostly of dried lava remnants, volcanic ash, sand and gravel. The desert covers an area of the Kīlauea Volcano along the Southwest rift zone. The area lacks any vegetation, mainly due to acid rainfall.
The terms lava stone and lava rock are more used by marketers than geologists, who would likely say "volcanic rock" (because lava is a molten liquid and rock is solid). "Lava stone" may describe anything from a friable silicic pumice to solid mafic flow basalt, and is sometimes used to describe rocks that were never lava , but look as if they ...
The small island, one of the Canary Islands, has been bracing for the lava to spill into the ocean after the volcano started erupting Sept. 19. In that time, the lava flow destroyed at least 656 ...
Rogers Dry Lake is an endorheic desert salt pan in the Mojave Desert of Kern County, California. The lake derives its name from the Anglicization from the Spanish name, Rodriguez Dry Lake . [ 4 ] It is the central part of Edwards Air Force Base as its hard surface provides a natural extension to the paved runways.
Magma that is extruded as lava is extremely dry, but magma at depth and under great pressure can contain a dissolved water content in excess of 10%. Water is somewhat less soluble in low-silica magma than high-silica magma, so that at 1,100 °C and 0.5 GPa , a basaltic magma can dissolve 8% H 2 O while a granite pegmatite magma can dissolve 11% ...
