How are the grand canyon and inner space cavern formed alike?

The Grand Canyon and Inner Space Cavern were both formed through geological processes involving erosion and water activity. The Grand Canyon was primarily shaped by the Colorado River cutting through rock over millions of years, while Inner Space Cavern formed from the dissolution of limestone by acidic groundwater, creating underground passages. Both locations showcase the power of water in shaping landscapes, highlighting the effects of erosion and natural processes over extensive periods.
