Erosional features are landforms created by the process of erosion, where natural forces like water, wind, and ice wear away rocks and soil. Common examples include valleys, canyons, and cliffs, which develop over time as these forces remove material from the Earth's surface. These features can be seen in various environments, such as riverbanks where flowing water carves out gorges or coastal areas where waves erode shorelines. Erosional features are important for understanding geological processes and the history of landscapes, as they reveal how the Earth has changed over millions of years.
