While it is true that both glaciers and ice floes are large masses of ice that can be found in arctic regions, there is a major difference between them. Basically, glaciers originate on land, and ice floes form in open water and are a form of sea ice.
A frost flower or ice flower is formed when thin layers of ice are extruded from long-stemmed plants in autumn or early winter. The thin layers of ice are often formed into exquisite patterns, curling into "petals" which resemble flowers.
An ice floe (/ floʊ /) is a large pack of floating ice often defined as a flat piece at least 20 m across at its widest point, and up to more than 10 km across. [1] Drift ice is a floating field of sea ice composed of several ice floes.
Lesson Overview. Day 1. Part 1 - (15 minutes) Polarstern Searches for a Suitable Ice Floe Use the Ice Floe Identification PPT to introduce students to the term, “ice floe” and to tell the story of the Polarstern searching for and attaching to a suitable ice floe.
Ice flowers are a natural phenomenon that occurs under specific conditions: calm, cold air over slightly warmer, still waters. As the temperature drops below freezing, the moisture in the air begins to crystallize, forming delicate, flower-like structures on the surface of the ice.
An iceberg is a large mass of freshwater ice that has broken off of a glacier or an ice shelf. An ice floe is a large, flat pack of floating ice. The difference between the two is that most of the ice floe’s mass is above the water’s surface, while about 90% of an iceberg’s mass is underwater.
