  1. The Earth & Rocks Visit www.worldofteaching.com For 100’s of free powerpoints

  2. Crust Mantle Core The Earth 10km to 100km thick Extends almost halfway to centreSolid properties but flows Iron & NickelJust over half the Earth’s radiusLiquid outer coreSolid inner core The average density of the Earth is much greater than the density of the rocks that form the crust. This means that the interior of the Earth is made from different and denser materials than the crust

  3. Sedimentary rocks Metamorphic rocks Igneous rocks The Rock Cycle LayersRipplesFossils Formed by high pressure & temperatureEvidence of mountain building processesAssociated with Earth movements Have been moltenCrystalsIntrusive – big crystalsExtrusive – small crystals

  4. Tilted Fractured Folded Upside down The Crust Young Sedimentary rocks in layersYounger rocks usually on top of older rocks Old Sedimentary rocks are also found: This shows that the Earth’s crust is unstable and has been subjected to very large forces
