What are some differences between canyons and gorges?

Canyons and gorges are both types of valleys carved by the erosive power of water. However, they have some characteristics that can set them apart:

1. Size: Canyons are generally larger than gorges. They can stretch for hundreds of miles and have a more extensive network of tributaries contributing to their formation. Gorges are often smaller and may represent a more confined segment of a canyon or a smaller valley.

2. Slopes: Canyons typically have steep sides but can also have some areas with gentler slopes as they become wider. Gorges, on the other hand, are known for their very steep and narrow walls.

3. Formation: While both canyons and gorges can be formed by the action of a river or stream cutting through rock, the term "gorge" is often reserved for particularly narrow canyons with a river running through them. They are also often associated with mountainous regions, where they may have been formed by rapid uplift and river incision.

4. Location: Canyons tend to be found in arid or semi-arid environments, where water flow is less frequent, and erosion occurs primarily during occasional heavy rainfalls or from river flow over a long period. Gorges could be located in various environments, including lush, forested regions.

5. Terminology: The terms "canyon" and "gorge" are sometimes used interchangeably, but in certain regions, the naming may follow local custom or reflect the features of the landscape. For instance, a small canyon might be classified as a gorge in one region due to its narrowness and steep sides.
