Are glaciers fresh water?

When a large chunk of an ice shelf or a glacier breaks off and floats into the sea, it forms and iceberg. Since all the glaciers and ice shelves are snow, i.e., frozen fresh water, the icebergs so formed are undoubtedly fresh water. When the sea water or saltwater freezes, it does so slowly.

Also question is, are glaciers on land or water?

Icebergs float in salt water, but they are formed from freshwater glacial ice. Melting icebergs will cause sea level to rise. Icebergs are already floating in the ocean, so melting will not raise sea level. Melting of land-based ice (such as glaciers) will raise sea level.

How much of a glacier is above the water?

You have probably heard the statistic that approximately 90 percent of an iceberg is found under water. That's an amazing statistic to consider given the massive size of some icebergs, but the very fact that ice floats is pretty remarkable.

Is the ice in Antarctica salt water?

When sea ice forms, most of the salt is pushed into the ocean water below the ice, although some salt may become trapped in small pockets between ice crystals. Water below sea ice has a higher concentration of salt and is more dense than surrounding ocean water, and so it sinks.
