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.

Lagoa may refer to the following places:
Lagoa (Portuguese pronunciation: [lɐˈɣoɐ]; Portuguese for lagoon) is a municipality in the southwestern part of São Miguel Island in the Azores. The population in 2011 was 14,442, in an area of 45.59 km². Lagoa is located east of Ponta Delgada, the island capital.
The area of Lagoa was settled just after the first colonists came to the island of São Miguel, and its first inhabitants established their homes in the areas that would eventually form the villages of Lagoa and Água de Pau. It is believed that early settlers chose the area for its sheltered bay, which was necessary for their loading and unloading of cargo, livestock and provisions. The Porto dos Carneiros was one of these areas, so named for the fact that sheep, as well as other animals, were offloaded within its cove. The celebrated Portuguese historian, Father Gaspar Frutuoso referred to Lagoa, in the way that the first settlers named it, a name that was dependent on where they made their homes:
It was in the area of the Church of Santa Cruz that most of these original founders established their homes, near an ancient lake (long since dried-up). In the 15th Century, the island of São Miguel continued to receive settlers and in Lagoa those colonists steadily settled farther to the west, around the bay that became known as Porto dos Carneiros, where fishing began to take on an important aspect of the local economy. To the east of the village of Lagoa, several families established agrarian settlements in the vicinity of Água de Pau.
Lagoa is a Portuguese wine region centered on the Lagoa municipality in the Algarve region. The region has Portugal's highest wine classification as a Denominação de Origem Controlada (DOC). The region is bordered to the west by the Portimão DOC and to the east by Tavira DOC. The region has been historically known for its fortified wine production but has been expanding its table wine production in recent years.
The principal grapes of the Lagoa region include Crato Branco, Negra Mole and Periquita.
