Most appear to have formed in the Pleistocene, and many are still developing, but there are relics of much older ones in palaeo-karst.

Caves can form over thousands or even millions of years. They typically form when underground water dissolves and erodes soluble rocks, such as limestone or dolomite. The exact timing of cave formation can vary depending on factors such as the geology of the area, the amount of water flow, and the local climate.

What are the different types of caves?

The main types of caves are solution caves, lava caves, sea caves, glacier caves, and talus caves. Solution caves form from the dissolution of soluble rocks like limestone; lava caves are created by flowing lava; sea caves are carved by the action of waves on coastal cliffs; glacier caves form within glaciers due to melting and refreezing processes; and talus caves are formed by fallen rocks creating cave-like structures.


Where do caves usually form?

Caves usually form in areas with limestone or other soluble rocks that can be dissolved by water over long periods of time. Common locations for cave formation include regions with karst topography, such as in limestone landscapes or near volcanic activity, where lava tubes can create caves.


Is there caves on mountains?

Yes, caves can form in mountains through various geological processes such as erosion, tectonic activity, or volcanic activity. These caves can provide unique ecosystems for plants and animals adapted to these dark and secluded environments.


What is the process of formation of caves?

Caves are formed through a process called speleogenesis, which involves the dissolution of soluble rocks like limestone, dolomite, or gypsum by groundwater. Over time, the water creates underground passages and caverns as it erodes and dissolves the rock, creating the intricate formations seen in caves. Other processes like tectonic activity, erosion, and lava flows can also contribute to cave formation.


Are all caves made of limestone?

No, not all caves are made of limestone. Caves can be formed in various types of rocks, including granite, sandstone, and volcanic lava flows. Limestone caves are common because limestone is soluble and can be eroded by water to create cave systems, but caves can also form in other types of rocks through different geological processes.
