Groundwater is weakly acid: it starts as rainwater that absorbs CO2 from the atmosphere, and this carbonic acid may be enhanced by acids from the soil. Most caves are in limestone, which is broken by joints, bedding-planes and faults that allow water to seep through from catchment to spring. The weakly acid water dissolves the limestone walls of the joints etc; in time creating tiny conduits that in suitable conditions eventually co-alesce and develop distinct cave passages.

Asturias Cave Art is located between Arcy and Ekain caves.
Groundwater plays a crucial role in the formation of caves by dissolving and transporting mineral deposits through the rock layers. As groundwater flows through the rock, it can create underground cavities and passages, leading to the formation of caves over time. Caves are commonly found where groundwater has shaped the rock over thousands to millions of years.

In limestone and sandstone areas, especially, ground water filtering through the rock and dissolving the limestone or sandstone, creates potholes, caverns and caves.
