The emergence of needle ice has been recognized as a geomorphic agent of soil disturbance, causing a number of small-scale landforms. [8] Needle ice phenomena play a particularly significant role in patterned ground in periglacial environments. [8] The growth of needle ice lifts a detached, frozen soil crust riding on top of the layer of ice.
Ice circles tend to rotate even when they form in water that is not moving. The ice circle lowers the temperature of the water around it, which causes the water to become denser than the slightly warmer water around it. The dense water then sinks and creates its own circular motion, causing the ice circle to rotate. [10]
Ice dam forming on slate roof. An ice dam is an ice build-up on the eaves of sloped roofs of heated buildings that results from melting snow under a snow pack reaching the eave and freezing there. Freezing at the eave impedes the drainage of meltwater, which adds to the ice dam and causes backup of the meltwater, which may cause water leakage ...

If ice or snow from your vehicle damages property or causes injury — for instance, damages another vehicle or causes an accident that hurts the driver or passenger — it could cost you $200 to ...
Abrasion is the natural scratching of bedrock by a continuous movement of snow or glacier downhill. This is caused by a force, friction, vibration, or internal deformation of the ice, and by sliding over the rocks and sediments at the base (that also causes an avalanche) that causes the glacier to move.
This wasn't your usual call for the local fire department. They responded after a large chunk of ice crashed through a Florida roof Monday. Pieces of ice were also scattered on the ground.
Spikes that grow from a crystallite formed below the surface of the water may project from the ice sheet at a steep angle, rather than perpendicular to it. [5] The ice spike process is rare - more commonly the surface freezes over entirely, and as water under the surface freezes it pushes all of the surface ice upward.
