  • Rock, Resources and Scenery
    • Igneous Rock
      • formation
        • magma from mantle cools and harden
      • types
        • intrusive
          • magma cool below earth surface
          • magma coold slowly
          • large crytsl formed
          • coarse texture
          • batholiths
            • large domes of cooled magma
        • extrusive
          • magma cool after volcano erupteed out
          • harden on earth surface
          • magma cools quickly
          • small crystal structure
          • fine texture
    • Sedimentary Rock
      • formation
        • layers of sediment= compacted together= solid rock
        • compaction process=
      • calcium carbonate
        • carboniferous limestone+chalk
        • shells and skeletons of dead sea creatures deposited onn sea bed= compacted together
      • mud and clay minerals
        • clays and shales
        • eroded particles from older rock- deposited on lake/sea beds= compacted together
    • Metamorphics Rock
      • formation
        • other rocks changed by heat and pressure
        • heat from earth's core
        • pressure from wight of material above
        • tectonic plates collide=rocks changed
        • magma from mantle heat rocks
      • harder and more compact
        • limestone =marble
        • clay= slate
    • rock cycle
      • igneous rock
        • weathering and erosion
          • sediment
            • compaction
              • Sedimentary rock
                • heat and pressure
                  • Metamorphic rock
                    • melting
                      • magma
                        • cooling
