Final answer:
Erosional landforms are primarily found in coastal areas, affected by wave action and weathering. Mountainous areas also feature erosional landforms shaped by glacial activity and water flow, while deserts are characterized by landforms created by wind erosion.
Step-by-step explanation:
Erosional landforms are predominantly found in coastal areas, where the nature of these landforms is largely determined by wave action and weathering processes. These areas are subject to constant change due to the dynamic interaction between the land and sea. Coastal features such as cliffs, arches, and caves are shaped over time by the erosive power of waves. Transporting of fragments through water also plays a significant role in the formation of these landforms.
In mountainous regions, erosional landforms are sculpted by glacial activity and the flow of water. As mountains erode, they release sediments that are deposited elsewhere, shaping the landscape in river valleys or near-shore environments. Over time, sharp peaks and serrated edges form as a result of water and ice erosion, creating dramatic and rugged terrain.
Deserts also feature erosional landforms, largely influenced by wind erosion. The landscape in these areas may include rock formations, mesas, and sand dunes, crafted by the abrasive action of wind carrying sand and other particles across the surface.
