O sinkholes, caves, and hot springs chemical and physical actions of groundwater.

Explanation:

Sinkholes, caves, and hot springs are formed from the actions of groundwater. The rock is made up of lime below the surface of sinkholes. These lime react with underground water and dissolve it which soften the rock and causes sinkholes. Caves are also formed when the water dissolve the limestone present in the rocks of the cave and slowly the degradation of rock will occur and caves are formed.
