A stack or sea stack 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. [1] Stacks are formed over time by wind and water, processes of coastal geomorphology. [2]
Aeolian landforms, or Eolian landforms, are produced by either the erosive or depositive action of wind. These features may be built up from sand or snow , [ 1 ] or eroded into rock, snow, or ice. Aeolian landforms are commonly observed in sandy deserts and on frozen lakes or sea ice and have been observed and studied around Earth and on other ...
Table – Raised landform with a flat top; Tidal marsh – Marsh subject to tidal change in water; Tepui – Table-top mountain or mesa in the Guiana Highlands of South America; Volcanic plateau – Plateau produced by volcanic activity; Wave-cut platform – Narrow flat area created by erosion
A truncated spur is a spur, which is a ridge that descends towards a valley floor or coastline from a higher elevation, that ends in an inverted-V face and was produced by the erosional truncation of the spur by the action of either streams, waves, or glaciers. Truncated spurs can be found within mountain ranges, along the walls of river ...
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape. [1] Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff.
A number of factors, ranging from plate tectonics to erosion and deposition (also due to human activity), can generate and affect landforms. Biological factors can also influence landforms—for example, note the role of vegetation in the development of dune systems and salt marshes, and the work of corals and algae in the formation of coral reefs.
Rauks are usually formed by wave erosion. [1] [5] On Öland and Gotland, rauks are chiefly formed along or near the escarpment known as the Baltic Klint. [4] Gotland rauks consist of limestone representing reefs that existed in the Silurian period. [4] [5] [10] As waves batter against limestone cliffs, pre-existing vertical fractures begin to ...
They are created by the wave driven erosion of cliffs along faults and bedding planes in the rock. Geos may have sea caves at their heads. Such sea caves may collapse, extending the geo, or leaving depressions inland from the geo. Geos can also be created from this process. [2]
