10 Famous Sea Stack Formations
To describe them, different rock structures that are formed by natural processes have been given various terms by geologists. A stack is a rock formation made up of a steep or upright column or columns of rock in the sea near a coast. They are formed when part of a headland is eroded by water crashing against the rock or as a result of wind erosion. These impressive formations are intricately created by nature only through time, tide and wind.
