Caves knowledge
Processes to form a void
There are many mechanisms leading to the formation of cavities and voids underground. Some caves are classified as “primary” because they are generated at the same time as the rocks containing them, others instead form subsequently, due to rock weathering that modify their original characteristics.
PRIMARY CAVES
- Formed by biologic processes (in coral reefs)
- Formed by lava flows
- Formed by cooling processes
SECONDARY CAVES
- Eolian caves
- Sea caves
- Tectonic caves
- Karst caves
