  2. Learning Outcome • Identify the economic value and uses of Rocks • Examine Human Interaction with the Rock Cycle during the process of Quarrying

  3. Economic Value of Rocks • Recreation; Hill walking, Climbing • Tourism; Burren • Decorative Pieces; Fireplaces, Headstones, Worktops • Construction Materials; Gravel, Limestone • Metals; Lead, Zinc, Gold • Energy Source; Coal, Oil, Gas, Geothermal

  4. Uses of Certain Rocks

  5. Quarrying • Important Resources • Construction Industry • Granite, Limestone and Marble are the most common rocks quarried in Ireland

  6. What is Quarrying? • Removal of Rocks from the Earths Surface • 400 active quarries in Ireland • In recent year with the improved developments in infrastructure in Ireland, there has been an increased demand for quarried materials

  7. Chapter 5: The Rock Cycle • Methods of quarrying I. Plug and feather • drilling holes • split the rock • extracting large pieces, e.g. floor covering II. Explosive • extracting large and small pieces of rock III. Channelling • machinery cuts large slices of rock • metamorphic rock such as marble

  8. Chapter 5: The Rock Cycle Positive impacts of quarrying • Direct employment • Construction • Indirect employment

  9. Chapter 5: The Rock Cycle Negative impacts of quarrying • Visual pollution • Noise pollution • Heavy machinery damage to infrastructure • Dust pollution • Water pollution • Disused quarries

  10. Case Study; Carrara Marble • Tuscany, Italy • White or blue-grey marble • Used since the time of ancient Rome • Statue of David – Michelangelo • Exported all around the world • Construction of buildings • Warm countries • Reflect light • Create an air of coolness
