More About Icebergs
Icebergs are made from fresh water. They come from places called glaciers. Glaciers are big sheets of ice that move slowly. When a piece breaks off, it becomes an iceberg.
Icebergs can be found in cold seas. They float around and can be very big. Some are small, but others are huge! They can be very old, too.
In the future, icebergs may melt more. This can change the sea. It is important to watch them and learn more.
