Ice
* Glaciers:
* U-shaped valleys: Wide, flat-bottomed valleys carved by glaciers.
* Cirques: Bowl-shaped depressions at the head of glaciers.
* Aretes: Sharp, jagged ridges separating cirques.
* Horns: Pointed mountain peaks formed by the intersection of multiple cirques.
* Moraines: Piles of rock and sediment deposited by glaciers (lateral, terminal, medial).
* Drumlins: Elongated hills of glacial till, shaped by ice flow.
* Eskers: Long, winding ridges of sand and gravel deposited by meltwater streams flowing within or under glaciers.
* Kettles: Depressions in the landscape formed when blocks of ice melt.
Wind
* Sand dunes: Mounds of sand shaped by the wind (e.g., barchan dunes, transverse dunes).
* Loess deposits: Fine, wind-blown silt that settles in thick layers.
* Ventifacts: Rocks shaped by abrasion from wind-blown sand.
* Yardangs: Streamlined, wind-eroded ridges.
Water
* Rivers:
* Canyons: Deep, narrow valleys carved by rivers.
* Floodplains: Flat, low-lying areas alongside rivers that are subject to flooding.
* Meanders: Winding bends in rivers.
* Oxbow lakes: U-shaped lakes formed when a meander is cut off from the main river channel.
* River deltas: Fan-shaped deposits of sediment at the mouth of a river.
* Oceans and Seas:
* Beaches: Accumulations of sand and other sediments along coastlines.
* Sea cliffs: Steep rock faces created by wave erosion.
* Sea stacks: Isolated rock formations separated from the mainland by wave action.
* Tombolos: Narrow spits of land connecting an island to the mainland.
* Barrier islands: Long, narrow islands parallel to the mainland, formed by wave action.
* Groundwater:
* Sinkholes: Depressions in the ground formed by the collapse of underground cavities.
* Caves: Underground cavities formed by the dissolving of rock.
Combinations of Ice, Wind, and Water:
* Glacial lakes: Lakes formed by the melting of glaciers.
* Tectonic landforms: Mountains, volcanoes, and fault lines can be modified by ice, wind, and water erosion.
Remember that these are just a few examples. The specific landforms created by ice, wind, and water depend on a variety of factors, including the type of rock, the climate, and the duration of the processes involved.
