Solution

Cave:
A natural cavity on weak rocks formed by the action of waves is called a cave.
Natural cavities are found principally in carbonate rocks due to the processes of sinkhole formation.
Caves are generally formed by the dissolution of limestone.
Rainwater takes carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid.
This slowly dissolves out the limestone along the joints, bedding planes, and fractures, some of which become enlarged enough to form caves.
Thus, A natural cavity on weak rocks formed by the action of waves is called a cave.
