  2. LABEL: Intrusive Igneous Rock (e.g. Granite) Sedimentary Rock Extrusive Igneous Rock (Pumice) Metamorphic Rock

  3. Granite Properties Family Intrusive Igneous rock Formed formed from magma inside the earth’s crust Distinctive features Tough, interlocking crystals Composed of feldspar and shiny quartz Colour Pink & White Both colours shine & sparkle Texture and granularity Granular, coarse-grained Location Mountains that have been caused by folding (e.g. Himalayas) Strengths & Weaknesses Resistant to physical weathering Crumbles when exposed to intense heat

  4. Locations of Granite in the UK • Granite forms some of the highest mountains in the world. Where can you find granite areas in the UK? • Mark and label these places on your map: • Dartmoor • Bodmin Moor • Land’s End • Grampian Hills • Scafell Pike • Galway Bay

  5. Tors • Granite areas have moorland scenery. • Granite is weathered along joints and cracks to produce a tor, consisting of rounded blocks that look like they have been stacked upon one another. • Draw & Label • A Tor • Blocks • Joints • Cracks

  6. Granite • LAND USE • Granite areas are of limited value for farming due to too much acidity and surface water, but they provide: • Good terrain for grouse and for military training. • Good for reservoirs because they are impermeable (water can’t get through) • Tors and bogs are great tourist attractions

  7. Uses of Granite & China Clay (Kaolin) Write down the uses of granite and kaolin
