Dear student,

A mushroom rock, also called rock pedestal or a pedestal rock, is a naturally occurring rock whose shape, as its name implies, resembles a mushroom. The rocks are deformed in a number of different ways: by erosion and weathering, glacial action, or from a sudden disturbance.
12.
These cavities become bigger and bigger and a time comes when only roof of the caves remain to form sea arches. Further erosion breaks the roof and only walls are left. These wall like features are called stacks. In this way, sea caves are turned into stacks.
(A) Flood plain: (i) Sea waves
(B) Sea cliff: (ii) Glaciers
(C) Moraines: (iii) Wind
(D) Sand dunes: (iv) River
13.
The erosion deposition of the sea waves gives rise to coastal landforms. Seawaves continuously strike at the rocks. As these cavities become bigger and bigger only the roof the caves remain, thus forming sea arches. Further, erosion breaks the roof and only walls are left.
Regards.
