Cliff-Top view of Botany Bay, Broadstairs, Kent
A stack or seastack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology. They are formed when part of a headland is eroded by hydraulic action, which is the force of the sea or water crashing against the rock. The force of the water weakens cracks in the headland, causing them to later collapse, forming free-standing stacks and even a small island. Without the constant presence of water, stacks also form when a natural arch collapses under gravity, due to sub-aerial processes like wind erosion. Stacks can provide important nesting locations for seabirds, and many are popular for rock climbing. It is said that Botany Bay found its name when those found in possession of smuggled goods were deported to Botany Bay in Australia; you may not see many smugglers on the sands these days, just holiday makers looking for a tranquil place to relax. When the tide is out, Botany bay is a great location for fossil hunting and exploring rock pools. There is plenty of exposed sand to enjoy when the tide is in, but due to the bay's shape the ends are cut off at high tide.
