Ice Types
There are several types of ice, each formed under different conditions. The most common type is glacial ice, which forms from compacted snow over long periods. This ice is found in glaciers and ice sheets, and it can be several meters thick. Another type is sea ice, which forms when ocean water freezes, typically in polar regions. Sea ice can vary in thickness and is crucial for marine ecosystems.
Frazil ice is another type, consisting of small, needle-like ice crystals that form in supercooled water. It often appears in rivers and can lead to the formation of larger ice structures. Lastly, pack ice refers to large areas of sea ice that have broken up and drifted together, commonly seen in the Arctic and Antarctic regions.
