la·va (lä v , l v)n. 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 l  b s, fall, from Latin lb , to fall.]Word History: Lava was appropriately named by people living near Mount Vesuvius. The only active volcano on the European mainland, Vesuvius has erupted frequently since Pompeii and Herculaneum were buried by it in a.d. 79. The Neapolitans who lived in the vicinity took the Italian word lava, meaning "a stream caused suddenly by rain," and applied it to the streams of molten rock coming down the sides of Vesuvius. The term was then taken into Standard Italian, where it came to mean the rock in both its molten and its solidified states. The Italian word in all its senses was borrowed into English around the middle of the 18th century (1750 being the earliest date of record). |
lava [ˈlɑːvə]
n
1. (Earth Sciences / Geological Science) magma emanating from volcanoes and other vents
2. (Earth Sciences / Geological Science) any extrusive igneous rock formed by the cooling and solidification of molten lava
[from Italian (Neapolitan dialect), from Latin lavāre to wash]
| lava (läv) 1. Molten rock that flows from a volcano or from a crack in the Earth. Most lava flows at a rate of a few kilometers per hour, but rates as high as 60 km (37 mi) per hour have been observed. Lava that contains abundant iron- and magnesium-rich components usually erupts with temperatures between 1,000°C and 1,200°C (1,832deg;F and 2,192°F). Lava that contains abundant silica- and feldspar-rich components usually erupts with temperatures between 800°C and 1,000°C (1,472deg;F and 1,832°F). Compare magma. 2. The igneous rock formed when this substance cools and hardens. Depending on its composition and the rate at which it cools, lava can be glassy, very finely grained, ropelike, or coarsely grained. When it cools underwater, it cools in pillow-shaped masses. See also aapahoehoepillow lava |
