Icicles

Icicles are elongated, tapering formations of ice that hang from edges like roofs, eaves, or branches. They develop when melting snow or ice on a surface refreezes as it drips downward in cold temperatures. As water repeatedly melts and refreezes, layers of ice build up, creating the characteristic cone or needle shape of an icicle. Their growth is influenced by factors such as temperature, sunlight, and the availability of water. Icicles can pose safety hazards if they grow large or heavy, and they also demonstrate natural processes of freezing and melting cycles in winter environments.
