Here's how:
* Gravity: Gravity pulls water downhill, creating the force that drives erosion.
* Hydrosphere: Water (in the form of rivers) acts as the erosive agent, carving out the canyon over time.
How it works:
1. Water flow: Water flowing in a river has kinetic energy.
2. Erosion: This energy erodes the rock and soil at the bottom and sides of the river channel.
3. Deepening and widening: Over long periods, the river channel becomes deeper and wider, forming a canyon.
4. Gravity's role: Gravity pulls the water downhill, maintaining the flow and the erosive power of the river.
Examples:
* The Grand Canyon (USA)
* The Yarlung Tsangpo Grand Canyon (Tibet)
* The Fish River Canyon (Namibia)
