    As the temperature continues to drop, the water on the surface may get cold enough to freeze and the lake/ocean begins to ice over.

    Ice shoves can be caused by temperature fluctuations, wind action, or changing water levels [3] and can cause devastation to coastal Arctic communities. Cyclical climate change will also play a role in the formation and frequency of ice shove events; a rise in global temperatures leads to more open water to facilitate ice movement.
