There are three (3) videos for you to watch.\n<\/p>\n

    \n
  1. The first is about Earth’s unique place in the solar system\n
    \"Earths<\/a><\/div>\n<\/li>\n
  2. The second is about Earth’s interior – most of the geosphere – and\n<\/li>\n
  3. The last video is about the workings of the outer part of Earth.\n<\/li>\n<\/ol>\n

    Points of interest<\/b>\n<\/p>\n

      \n
    • The geosphere encompasses the solid and molten rocky portions of Earth\n<\/li>\n<\/ul>\n
        \n
      • Planet Earth is the third planet from the sun and the largest of the rocky planets\n<\/li>\n<\/ul>\n
          \n
        • Three main shells make up the Earth: core, mantle and crust\n<\/li>\n<\/ul>\n
            \n
          • Geomagnetism is the result of a liquid outer iron-nickel core convecting around a solid inner iron-nickel core and is fundamental in keeping Earth’s atmosphere\n<\/li>\n<\/ul>\n
              \n
            • Plate tectonics, where the lithosphere \u201cfloats\u201d on the asthenosphere is the main driver producing the features on the surface of the Earth, including volcanism and earthquakes. It is also an important influence on topography and the amalgamation and break up of continental masses over time\n<\/li>\n<\/ul>\n
