Atomic structure shifts are not conventionally considered ‘moving’. Most people wouldn’t call water turning to ice a ‘movement’.

Just wait til you hear about supersolids
I was thinking of when water gets over boiling point and then is disturbed:

A glacier is compacted snow, not ice

I can warrantee you compacted snow is ice. Just go to Greenland, Argentina or Switzerland and see a glacier by yourself. You see ice and bubbles(bubbles could grow and become caves and over time they go up).
Icebergs are called ICE- berg for a reason, not snow-bergs.
If you had a snow that is 1/10 the density of water, just 10 meters of snow means 1 atmosphere of pressure. That pressure compresses the snow, making 10 meters hold more water and more pressure.
There are places in the world with glaciers higher than three kilometers(1.8 miles).
