Jääliikumine

Jääliikumine refers to the movement of ice, a phenomenon observed in various environments, most notably in glaciers and on frozen bodies of water. Glacial ice moves due to the immense pressure of its own weight, causing it to deform and flow downhill. This process is slow, often measured in centimeters or meters per year, but it is a significant force in shaping landscapes through erosion and deposition. The speed of glacial movement is influenced by factors such as temperature, the slope of the underlying bedrock, and the presence of meltwater.

On lakes and oceans, ice movement is primarily driven by wind and currents. Wind can push large ice floes and sheets across the water surface, creating pressure ridges where they collide. Ocean currents also exert a force on sea ice, influencing its drift patterns. This movement can have considerable impacts on navigation, coastal erosion, and marine ecosystems. The extent and direction of ice movement on water bodies are important indicators of weather patterns and climate change. Understanding jääliikumine is crucial for fields ranging from glaciology and oceanography to environmental science and polar logistics.
