Explanation:

Bands of limestone emerge from the Earth's surface in often spectacular rocky outcrops and islands. Examples include the Burren in Co. Clare, Ireland; the Verdon Gorge in France; Malham Cove in North Yorkshire, England; Fårö, near the Swedish island of Gotland; the Niagara Escarpment bordering Canada and the United States; Notch Peak in Utah; and the Ha Long Bay National Park in Vietnam. In addition, Belgium and Holland have several huge quarries, with a total gallery length of more than a hundred kilometers. An example of a hill with a lot of quarries is Mount Saint Peter (in the Belgium-Netherlands region).
