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.

Surname:

Anarky

Anarky is a fictional character, appearing in comic books published by DC Comics. Co-created by Alan Grant and Norm Breyfogle, he first appeared in Detective Comics No. 608 (November 1989), as an adversary of Batman. Introduced as Lonnie Machin, a child prodigy with knowledge of radical philosophy and driven to overthrow governments to improve social conditions, stories revolving around Anarky often focus on political and philosophical themes. The character, who is named after the philosophy of anarchism, primarily espouses anti-statism; however, multiple social issues have been addressed through the character, including environmentalism, antimilitarism, economic inequality, and political corruption. Inspired by multiple sources, early stories featuring the character often included homages to political and philosophical books, and referenced anarchist philosophers and theorists. The inspiration for the creation of the character and its early development was based in Grant's personal interest in anti-authoritarian philosophy and politics. However, when Grant himself transitioned to the philosophy of Neo-Tech, developed by Frank R. Wallace, he shifted the focus of Anarky from a vehicle for socialist and populist philosophy, to rationalist, atheist, and free market-based thought.
