Canyon, an Uncommon card

The card carries these facts from its Wikipedia article.

• Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream.
• A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains.
• The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering.
