Caves can be formed by many geological processes including chemical actions, erosion from water, tectonic and volcanic forces, microorganisms, and pressure.
The most common type of cave formation are solutional caves which are formed by natural acids in groundwater dissolving soluble rock such as limestone (or sometimes chalk, dolomite, marble or gypsum).
Primary caves are formed at the same time as the surrounding rock, the most common type are lava tubes. As lava flows downhill the surface cools and hardens, yet underneath, hot lava continues to flow leaving behind a hollow tube.
