• landslide
• weathering
• erosion

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.

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:

• ice wedging
• chemical weathering
• acid rain
• abrasion

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging
• acid rain
• permeability
• abrasion

These gravestones have slowly broken down and turned a blackish color due to the action of:

• ice wedging
• abrasion
• acid rain
• mechanical weathering
