Answer:
The caves were caused by erosion from waves.
Step-by-step explanation:
The cave is an inhospitable but oxygen-filled underground space, large enough to be examined and studied by man, especially for its peculiar formations and the different life forms contained in these spaces. There are several types of cave, among these types we can mention the marine caves that are created by the erosion of the waves.
Waves are formed by the joint action of wind and water, their effects are noted in lake, coastal and riverbank environments. The impact of the waters (ebb and flow) on the banks causes the disintegration of material, which remains suspended and is later deposited at the bottom of rivers, lakes, seas etc. This disintegration is what causes erosion and the origin of the marine caves.
