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 ...
Sep 23, 2024 · Lava, magma (molten rock) emerging as a liquid onto Earth’s surface. The term ‘lava’ is also used for the solidified rock formed by the cooling of a molten lava flow. Lava, which is exceedingly hot (about 700 to 1,200 degrees C [1,300 to 2,200 degrees F]), can be very fluid, or it can be extremely stiff, scarcely flowing.

The liquid-filled inventor proceeded to purchase the equally liquid-filled lamp, whose creator (Mr. Dunnett) Walker later discovered had died. Walker became determined to make a better version of the novelty item and spent the next decade and a half doing so (in between running an international house-swap agency and making films about nudism.)

When a volcano erupts or a deep crack occurs in the Earth, the magma rises and overflows. When it flows out of the volcano or crack, usually mixed with steam and gas, it is called lava. Fresh lava ranges from 1,300° to 2,200° F (700° to 1,200° C) in temperature and glows red hot to white hot as it flows. Enormous quantities of lava, enough ...
