FROST ACTION



Example Type:
Earth Erosion
Mechanical Weathering

Information:
Location: Mountainside
Record Date: 11.01
Season: Fall
Elevation: 3400 Feet

Notes:
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.
