Icebergs are freshwater because they originate as frozen chunks of fresh water that began their life on land, not from the ocean.
Here's how icebergs form as freshwater:
- Origin on Land: Icebergs are not pieces of frozen ocean water. Instead, their formation starts on land.
- Snowfall Accumulation: The process begins when snow falls in a region of land that is too cold for the snow to melt.
- Freshwater Buildup: Over extended periods, this non-salty snow gradually builds up on the ground, compacting into ice over time, which eventually forms glaciers. When these glaciers reach the sea and break off, they become freshwater icebergs.
