How long to erode a canyon?

Answer 1

The time it takes to erode a canyon varies significantly based on factors such as the type of rock, climate, water flow, and geological activity. Some canyons, like the Grand Canyon, have taken millions of years to form through persistent erosion by rivers and weathering processes. In contrast, smaller canyons can erode much more quickly, potentially within thousands to tens of thousands of years, depending on environmental conditions. Overall, canyon erosion is a gradual and complex process influenced by a multitude of natural factors.
