When the root of a coastal cave collapsed it forms?
Answer Details
When the root of a coastal cave collapses, it forms a geo. A geo is a narrow steep-sided inlet formed in coastal cliffs by the erosion of the sea. It is often created when a section of a sea cave roof collapses, leaving an opening to the sea. Over time, the waves will continue to erode the geo, deepening it and widening it to create a larger inlet. Geos are common features along the coasts of many countries and can be home to a variety of marine life.
