Earth Erosion

Frost action is a type of weathering where water actually seeps into cracks in the rock. The water freezes as the temperature drops. As water freezes it expands. This expansion creates a wedge inside the rock, encouraging is to crack and split apart. This picture shows one of those fractures.
