Weathering, Erosion, and Deposition

Front

What is ice wedging?

Back

Ice wedging starts when it rains. The rain goes into a rock, then freezes. The freezing expands and breaks the rock.

Back

The process of BREAKING DOWN rocks and minerals.

Front

How are the rocks at the TOP of the mountain different from the rocks at the BOTTOM?

Back

Rocks at the top of the mountain are different from rocks at the bottom because of ice or root wedging splits the rock.

The rocks at the top are smaller and sharper, where the rocks at the bottom are larger and smoother.

Front

What is root wedging?

Back

Root wedging is the process where root growing causes rocks to break apart.
