1. Erosion:
* Canyons: Formed by the erosive power of rivers over millions of years. The Grand Canyon is a prime example.
* Valleys: Can be formed by rivers, glaciers, or wind erosion.
* Badlands: Eroded landscapes with steep slopes and sharp ridges, often found in arid regions.
* Sand dunes: Created by wind erosion and deposition of sand.
* Sea cliffs: Formed by wave erosion of coastal rock.
2. Deposition:
* Alluvial fans: Cone-shaped deposits of sediment formed at the base of mountains where rivers emerge.
* Deltas: Landforms created at the mouth of rivers where they deposit sediment into a body of water.
* Sandbars: Linear accumulations of sand found in rivers and along coastlines.
* Beaches: Deposits of sand and other sediment along coastlines.
* Glacial moraines: Accumulations of rock and sediment deposited by glaciers.
3. Volcanic Activity:
* Volcanoes: While most volcanoes are associated with plate boundaries, some can form in the middle of tectonic plates (hotspots). The Hawaiian Islands are an example.
* Calderas: Large depressions formed by the collapse of a volcanic cone after an eruption.
4. Other Processes:
* Sinkholes: Depressions formed by the collapse of underground cavities, often associated with karst topography.
* Karst landforms: Unique landforms created by the dissolution of soluble rock, like limestone. This includes caves, sinkholes, and towers.
* Meteorite impact craters: Large depressions created by the impact of asteroids or meteoroids.
It's important to note that even landforms formed independently of plate boundaries are often influenced by tectonic activity in the long term. For example, the uplift of mountains can create conditions for erosion that shape canyons and valleys, while the presence of faults can influence the location and formation of sinkholes.
