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.

The Cave (video game)

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.

    No matter what i feel
    the words to describe
    won't come out
    it's like i'm trying to contain myself
    my thoughts and hopes and doubts and fear
    are trapped inside
    and they won't come out
    as long as they are here
    i will be here
    as long as they stay here
    i will stay here
