How are canyons formed?

• Wind blows sand into high piles, which form the canyon walls.
• Rivers erode soil and rock over time, leaving behind canyon walls.
• Gravity causes rocks to fall from mountain sides onto valley floors.
• Ice freezes and thaws in cracks of rocks, and the cracks become canyons.
