Rock (geology)

In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.

Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.

Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.

Classification

At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO₂); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.

Jupiter (roller coaster)

Jupiter (Japanese: ジュピター) is a wooden roller coaster at Kijima Kogen, an amusement park in Beppu, Ōita Prefecture, Japan.

Opening in 1992 (although other sources report that it opened in 1993), Jupiter was the first wooden roller coaster in Japan and the only wooden roller coaster in Japan until White Canyon opened at Yomiuriland amusement park and White Cyclone opened at Nagashima Spa Land amusement park (both in 1994). At over 1,600 metres (5,200 ft) in length, Jupiter is the 7th longest wooden roller coaster in the world.

History

Although Japan has had numerous notable roller coasters—including coasters that have held the record of world's longest, world's fastest, and world's tallest roller coaster—it has had relatively few wooden roller coasters. This resulted from Japanese earthquake engineering regulations that restricted the construction of tall wooden structures. It was not until after these restrictions were modified that Jupiter (and later White Canyon and White Cyclone) could be constructed.

Jupiter (magazine)

Jupiter is a science fiction magazine and is edited by Ian Redman. The magazine was first published in July 2003. Based in the United Kingdom, Jupiter has garnered a solid reputation as a dependable small press in its respective field, as noted by SF Crowsnest, and is a publication which SFRevue calls "an amusing journey".Jupiter, published four times a year, is produced in a minimalist style (i.e. monochrome cover, no interior illustrations, brief editorial, no non-fiction and stapled in the middle). Each issue is named after one of the Jovian satellites, with the traditional number of the moon matching the issue number of the magazine.

While the strength of each issue wavers—and although there is no pay—this has not stopped Jupiter from attracting rising stars in the field of speculative fiction, such as the Clarke-Bradbury award winner Lavie Tidhar, David Ireland, Eric S. Brown, David Conyers, Peter Tennant, Andrew Hook and Anubis nominee Carmelo Rafala.
