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

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place
• makes the rocks last longer
• expands cracks and breaks rocks
• causes rocks to fall in landslides

the process of wearing down by friction - like sand blasting

• exfoliation

• abrasion

• erosion

• deposition

the process by which layers or sheets of rock gradually break off

• Release of Pressure

• abrasion

• erosion

• deposition
