Rhyolite (/ ˈraɪ.əlaɪt / RY-ə-lyte) [1][2][3][4] is the most silica -rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase.
Steve is a player character from the 2011 sandbox video game Minecraft. Created by Swedish video game developer Markus "Notch" Persson and introduced in the 2009 Java-based version, Steve is the first of nine default player character skins available for players of contemporary versions of Minecraft. Steve lacks an official backstory as he is ...
Herobrine is an urban legend and creepypasta from the video game Minecraft, originating from an anonymous post on the imageboard website 4chan in 2010. He is depicted as a version of the Minecraft character Steve, but with solid white eyes that lack pupils. In numerous iterations, Herobrine has possessed several different unnatural abilities ...
Aerial view of a lava lake in Pu’u ’Ō’ō crater, east rift zone of Kīlauea. The crater is about 820 ft (250 m) in diameter. Aerial view of a lava lake atop the Kūpaʻianahā vent on the east rift zone of Kīlauea volcano. Lava lakes are large volumes of molten lava, usually basaltic, contained in a volcanic vent, crater, or broad ...
The new lava dome grew to fill the crater. From 1951 to 1953, new lava domes formed and collapsed, generating more pyroclastic flows. The dome eventually attained a height of 450 meters from the crater floor to its summit and had a volume of 0.2 km 3 (0.048 cu mi). [4] A lava spine emerged from the dome and grew to a height of 150 m (490 ft ...
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 ...
LAVA takes their inspiration from nature, using the principle of biomimetics. [3] Future technologies are merged with the patterns of organisation found in nature to build a smarter, friendlier, more socially and environmentally responsible future. [4] LAVA uses computation to simulate the natural behavior of growth and adaptation of species.
Lava tubes are cave-like volcanic straights formed by the hardening of overlaying lava. These structures help further the propagation of lava, as the walls of the tube insulate the lava within. [29] Lava tubes can account for a large portion of shield volcano activity; for example, an estimated 58% of the lava forming Kīlauea comes from lava ...
