Iceberg

Tap it to break off a chunk into the sea.

An iceberg is a huge piece of ice that has broken off a glacier or an ice shelf and floats out to sea. It is made of fresh water that fell as snow long ago. Ice is a little lighter than seawater, so an iceberg floats, but only about one tenth of it shows above the water.

When a chunk breaks off, it is called calving. Tap it and a chunk cracks off, showing fresh pale ice, and tips into the sea with a splash of spray and rings of ripples. The chunk bobs, and the iceberg, now lighter, bobs and rocks. Then the chunk melts away and the splash grows it back.
