The effect of expansion during freezing can be dramatic, and ice expansion is a basic cause of freeze-thaw weathering of rock in nature and damage to building foundations and roadways from frost heaving. It is also a common cause of the flooding of houses when water pipes burst due to the pressure of expanding water when it freezes. [9]
Water expands by 9% as it freezes. Occasionally the surface can freeze over except for a small hole; the continuing freezing and expansion of water that is below the surface ice then slowly pushes the remaining water up through the hole. Reaching very cold air, the edge of the extruded water freezes while remaining liquid in the center.
These events, known as frost quakes, occur when plummeting temperatures cause water in the ground to freeze. As the ice expands, stress builds up in the ground, and when the pressure becomes too ...
Window frost (also called fern frost or ice flowers) forms when a glass pane is exposed to very cold air on the outside and warmer, moderately moist air on the inside. If the pane is a bad insulator (for example, if it is a single-pane window), water vapour condenses on the glass, forming frost patterns.
Early in a freezing rain event, bridges, roads and metal surfaces become coated with a clear, thin layer of ice that makes them slippery. This ice is often referred to as "black ice" because it is ...

Certain frost-susceptible soils expand or heave upon freezing as a result of water migrating via capillary action to grow ice lenses near the freezing front. [2] This same phenomenon occurs within pore spaces of rocks. The ice accumulations grow larger as they attract liquid water from the surrounding pores.
A rapid temperature drop from approximately freezing to near or below −18 °C (0 °F), which ordinarily occurred on a timescale of 16 to 48 hours. [1] Cryoseisms typically occur when temperatures rapidly decrease from above freezing to subzero, [4] [9] and are more than likely to occur between midnight and dawn (during the coldest parts of ...
