AI overview
Chalk is a soft, white, porous rock made of calcite that formed from the accumulated shells and hard parts of tiny sea creatures compressed over millions of years. It is commonly found in Western Europe, where it creates distinctive white cliffs, such as the famous Dover cliffs in England, where it meets the sea.
