Back

erosion

Front

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

Back

physical weathering

Front

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

Back

chemical weathering

Front

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

Back

abrasion

Front

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

Back

ice wedging

Front

This rock may chemically weather easily because it has many spaces or holes in it that allow water to seep through it, meaning it is:

Back

permeable

Front

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

Back

acid rain

Front

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

Back

Weathered mountain would be rounder and less jagged.

Front

How is physical weathering different from chemical weathering?

Back

Chemical weathering changes the chemical composition of rocks; physical weathering does not.
