Cave

A cave or cavern is a hollow place in the ground, especially a natural underground space large enough for a human to enter. Caves form naturally by the weathering of rock and often extend deep underground. The word cave can also refer to much smaller openings such as sea caves, rock shelters, and grottos.

Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called caving, potholing, or spelunking.

Types and formation

The formation and development of caves is known as speleogenesis. Caves are formed by various geologic processes and can be variable sizes. These may involve a combination of chemical processes, erosion from water, tectonic forces, microorganisms, pressure, and atmospheric influences.

It is estimated that the maximum depth of a cave cannot be more than 3,000 metres (9,800 ft) due to the pressure of overlying rocks. For karst caves the maximum depth is determined on the basis of the lower limit of karst forming processes, coinciding with the base of the soluble carbonate rocks.

Cave, Lazio

Cave is a town and comune in the Latium region of Italy, 42 kilometres (26 mi) southeast of Rome. As of 2011 its population was of 10,421.

History

The town was mentioned first in 998 AD, and was later a fief of the Colonna family. In 1482 it was besieged by Pope Sixtus IV and obliged to surrender. It is especially known for the Treaty of Cave, signed on 12 September 1557 by plenipotentiaries of Pope Paul IV and Fernando Álvarez de Toledo, the Spanish viceroy of Naples.

Geography

Cave borders with Castel San Pietro Romano, Genazzano, Palestrina, Rocca di Cave, and Valmontone. It counts the hamlets (frazioni) of Collepalme and San Bartolomeo.

Cave (song)

"Cave" is the second single by English alternative rock band Muse, and the second to be released from their debut album, Showbiz. It was released on 7" vinyl—backed with an instrumental remix of the song—and double CD—backed with a remix of the song alongside "Twin," "Host," and "Coma";—on 6 September 1999 and reached #52 in the UK Singles Chart—an improvement of 21 positions on "Uno". In the United States a five-track extended play was also released by Maverick Records. "Cave" also appears on the soundtrack for the film Little Nicky.

Background

Bellamy has given two statements about what Cave is about. Once he said it was about "an old friend of mine" in a strangely warbled voice before a live performance of the song and on a different occasion he stated "The idea for Cave came from that rubbish American book, Men Are From Mars, Women Are From Venus. There's this bit about how men go into a cave when they get stressed and I think that's probably true, although, personally, I tend to let it out. I did have a bit of a tantrum in my hotel bathroom last night - but I managed to repair the toilet, so that's OK."

Warrior

A warrior is a person specializing in combat or warfare, especially within the context of a tribal or clan-based warrior culture society that recognizes a separate warrior class or caste.

Warrior classes in tribal culture

In tribal societies engaging in endemic warfare, warriors often form a caste or class of their own. In feudalism, the vassals essentially form a military or warrior class, even if in actual warfare, peasants may be called to fight as well. In some societies, warfare may be so central that the entire people (or, more often, large parts of the male population) may be considered warriors, for example in the Iron Age Germanic tribes and Indian clans like the Rajputs.

Women as warriors

While the warrior class in tribal societies is typically all-male, there are some exceptions on record where women (typically unmarried, young women) formed part of the warrior class, particularly in pre-modern Japan.

A purported group of fighting women is the legendary Amazons, recorded in Classical Greek mythology. Similarly, the Valkyrie are depicted in Norse mythology, particularly the Icelandic Etta.

Warriors (1984 album)

Warriors is the second studio and the second self-titled album from former Yugoslav/Canadian heavy metal band Warriors. It is the last Warriors release.

The album cover was, with a slightly different Warriors logo, originally used as a Ratnici - Warriors EP cover.
