Here are some key characteristics of a ravine:
* Deep: Ravines are significantly deeper than a simple ditch or gully.
* Narrow: They are usually much longer than they are wide.
* Steep sides: The sides of a ravine are often quite vertical and difficult to climb.
* Erosion: They are typically formed by the erosive action of water, wind, or ice.
Think of a ravine as a mini-canyon, a small but impressive example of the power of nature to shape the land.
