GEOSPHERE (DEFINITION (The geosphere is the solid part of the Earth system…

- - - - Solid: under room temperatures
      - Natural: not artificial or produced by human action
      - Chemical Composition: always the same elements in the same proportion form the same mineral. They also have chemical formula, unique for each mineral.
      - Crystalline Structure: They form geometric structures; sometimes we can even see it, with edges and flat faces. Some other times, we need a microscope to check it
      - Inorganic: not produced by living organisms
- - - - Sedimentary Rocks: They are formed by the accumulation of sediments: small parts of other broken rocks. In this group we find limestone, gypsum and marlstone
      - Igneous Rocks: They are formed from magma. Magma is a mixture of melted rocks at the centre of the Earth. We can found it when a volcano erupts. Here we can find granite and basalt.
      - Metamorphic Rocks: They are formed from another rock that suffers high temperatures and pressures, so the minerals changes in composition and distribution. The result is a completly different rock, we can find slate, quartzite and gneiss in this group.
