sea caves- by Leonard Khoo Wei Quan

What is a sea cave?

A sea cave is a type of geographical feature or a hollow opening that has been formed by wave action. It is usually formed in a cliff by mechanical erosion of the cliff by oceanic waves.

How are sea caves formed?

Sea caves are formed by waves of water continually slamming against weak spots in the rock walls. Erosion happens everywhere, but where there is a weak spot, it happens faster. Weak spots are generally found where there is fault, a break, or when two different surfaces touch each other and one is weaker than the other, such as a dike. Therefore, while one area may take 150 years to make a cave, a weakened area may form a cave in half that time.
