What happens after a stack is formed?

Answer 1

Stacks are formed by headlands turning into caves, caves turning into arches and arches turning into stacks. Stacks can then even turn into stumps. This all happens from erosion and weathering.

Answer 2

Stacks are formed by headlands turning into caves, caves turning into arches and arches turning into stacks. Stacks can then even turn into stumps. This all happens from erosion and weathering.

Answer 3

The cliff face is eroded by hydraulic action, which over time forms a cave. The back and roof of the cave is then eroded until it breaks through the headland forming an arch. Further erosion on the arch causes it to collapse, thus forming the stack. More erosion on the stack will cause it to form a stump.

Answer 4

It is non-existent. In order to form a stack you must first instantiate one, but before that point there is no stack in memory therefore it does not exist. Once instantiated, however, it becomes an empty stack, unless the stack was instantiated from a single element, in which case it has one element, or it was instantiated from another container (which could be another stack), in which case it will have the same number of elements as that container.

Answer 5

Stacks at Torre Sant'Andrea, southern Italy.

A stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, isolated by erosion.[1] Stacks are formed through processes of coastal geomorphology, which are entirely natural. Time, wind and water are the only factors involved in the formation of a stack.[2] 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 archcollapses 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.

Raukar (stacks) on the island of Fårö

FormationThe formation process usually begins when the sea attacks small cracks in a headland and opens them. The cracks then gradually get larger and turn into a small cave. When the cave wears through the headland, an arch forms. Further erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast - the stack. Eventually, erosion will cause the stack to collapse, leaving a stump. This stump is usually a small rock island, small enough to be submerged by high tide. Other languagesThe term kekur (Russian: кекур) is used for the stacks in the Arctic and Pacific oceans, in the Russian Far East, and for stone columns in the watersheds of the Lena, Yana andIndigirka Rivers.[3]

The Swedish rauk refers to a stone column created by natural erosion. Examples are found on the islands of Gotland, Fårö and Öland.

Answer 6

The headlands soft rock is eroded away by hydraulic action and abrasion this creates arches, later these arches collapse leaving stacks. Another way this can also happen is the cliff face is eroded by hydraulic action, which over time forms a cave. The back and roof of the cave is then eroded until it breaks through the headland forming an arch. Further erosion on the arch causes it to collapse, thus forming the stack. More erosion on the stack will cause it to form a stump.

Answer 7

After a stack is formed, new items are added or pushed onto the top of the stack. Items are also removed or popped from the top of the stack. This follows the Last In, First Out (LIFO) principle where the most recently added item is the first one to be removed.
