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

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

How might a weathered mountain appear different than an unweathered mountain?

• Weathered mountain would be taller.

• Weathered mountain would be rounder and less jagged.

• Weathered mountain would be more jagged and less rounded.

• Weathered mountain would have no trees.
