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.
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.
The Cave is a puzzle-platform/adventure video game developed by Double Fine Productions and published by Sega in January 2013 on the PlayStation Network, Nintendo eShop and Xbox Live Arcade storefronts via the PlayStation 3, Wii U and Xbox 360 consoles and on Steam for Microsoft Windows, OS X and Linux. It was later released on October 3, 2013 on iOS devices, and on December 2, 2013 on the Ouya.
The game was created by Ron Gilbert, building on an idea that he has had for nearly twenty years about a cave that lures people into it to explore their darker personality traits. The game is rated "teen" for blood and violence. The game borrows concepts from his earlier 1987 game, Maniac Mansion, in which the player initially selects three different characters from a cast of seven to explore the Cave. Many of the game's puzzles require the three characters to work in coordination to complete, while some puzzles are specific to the unique abilities of a character; in this manner the Cave can only be fully explored through multiple play-throughs.
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.
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.
Cave borders with Castel San Pietro Romano, Genazzano, Palestrina, Rocca di Cave, and Valmontone. It counts the hamlets (frazioni) of Collepalme and San Bartolomeo.

DFC may refer to:
The Distinguished Flying Cross is the third-level military decoration awarded to personnel of the United Kingdom's Royal Air Force and other services, and formerly to officers of other Commonwealth countries, instituted for "an act or acts of valour, courage or devotion to duty whilst flying in active operations against the enemy".
The award was established on 3 June 1918, shortly after the formation of the RAF. It was originally awarded to Royal Air Force commissioned and warrant officers. During World War II it was awarded to Royal Artillery officers serving on attachment to the RAF as pilots-cum-artillery observers. Since World War II, the award has been open to army and naval aviation officers, and since 1993 to other ranks; the Distinguished Flying Medal, awarded to other ranks, has been discontinued. Recipients of the Distinguished Flying Cross are entitled to use the post-nominal letters "DFC". A bar is added to the ribbon for holders of the DFC who received a second award.
DFC was an American hip hop duo composed of Flint, Michigan natives Alpha "Al" Breed and Bobby "T-Dub" Thompson. They were closely associated with MC Breed who was also Al's cousin.
DFC stands for Da Funk Clan.
MC Breed and DFC released their collaborative debut album on November 11, 1991 entitled MC Breed & DFC, which charted at 142 on the Billboard 200 and featured their most successful single, "Ain't No Future in Yo' Frontin'".
After MC Breed & DFC, DFC signed with Atlantic Records and were placed on their subsidiary Big Beat Records. They then released 1994's Things in tha Hood which became their most successful album, peaking at 71 on the Billboard 200 and spawning the singles "Caps Get Peeled" and "Thing in tha Hood". They followed up with 1997's The Whole World's Rotten, but disbanded in 1999 after appearing on MC Breed's It's All Good.
