To tell if the ice is from an iceberg or sea ice, you can look for a few key differences:
1. **Air Bubbles**: Icebergs often have bubbles trapped in them because they come from glaciers. Sea ice usually has fewer bubbles and may be more transparent.
2. **Salt Content**: Sea ice contains salt, while icebergs are made from fresh water. You could taste a tiny bit of the ice (if safe) – if it tastes salty, it's probably sea ice.
3. **Texture**: Icebergs are usually smooth and may have a bluish tint, while sea ice can be rough and often has a white, opaque appearance.
4. **Layering**: Sea ice often has layers due to freezing and thawing, while iceberg ice is typically denser and more solid.
