Stacks (geology)

In geology, "stacks" refer to geological formations that are typically characterized by vertical columns of rock that rise abruptly from the surrounding landscape, often found near coastlines. These structures are formed through processes of erosion, where softer rock layers are worn away by waves and weather, leaving behind more resistant rock that stands taller than the surrounding area. Stacks are usually associated with sea cliffs and are often remnants of larger rock formations that have been eroded over time.
