Vocabulary of ice

I came across a link that provides some language for ice.

At first there is frazil ice, make up of crystals.   It can develop into slush flows, not unlike lava.

As there is more freezing, these can coalesce into pancake ice,

Border ice forms at the edge of the shore and grows toward the middle.  It is also known as  “fast” ice, because it is fastened to the shore.

If the fast ice breaks away from the shore, often from changes in the water level, it is plate ice.

With further cooling, there will be freeze up.

With more cooling, there will be sheet ice, covering the entire river.
