  2. 2. Vocabulary Minerals – a natural, inorganic solid with a definite chemical composition and a characteristic internal structure.
  3. 3. Vocabulary Igneous Rock - from cooled and hardened magma or lava.
  4. 4. Vocabulary Weathering – change in the physical form or chemical composition of rock materials exposed at Earth’s surface.
  5. 5. Vocabulary Sedimentary Rock – rock formed from compressed or cemented deposits of sediments.
  6. 6. Vocabulary Fossils – the traces of remains of a plant or an animal found in sedimentary rocks.
  7. 7. Vocabulary Metamorphic rock – rock formed from other rocks as a result of heat, pressure, or chemical processes.
  8. 8. Igneous Rock The faster the rock cools the less the crystals grow.
  9. 9. Igneous Rock Obsidian rocks are smooth stones used by early American Indians to make tools. Their composition is much like that of granite.
  10. 10. Igneous Rock Obsidian becomes smoother as they cool much more quickly. Because they cool more quickly, they have less or no crystals.
  11. 11. 2 kinds of Igneous Rock
  12. 12. 2 kinds of Igneous Rock Extrusive igneous rock cools on Earth’s surface.
  13. 13. 2 kinds of Igneous Rock  Intrusive igneous rock forms from magma that cools while trapped beneath Earth’s surface.  They are insulated and cools off slowly
  14. 14. 2 kinds of Igneous Rock  Because of long cooling period, the crystals form.  Crystals on intrusive igneous are larger than those on extrusive igneous.
  15. 15. Weathering Weathering is the process by which rocks are broken down as follows:  Pieces of boulders fall down hillsides due to gravity, wind or rain.  Rivers carry rocks down into deltas, lakes or the sea.  Waves beating against cliffs.
  16. 16. Weathering Gravity, waves, rivers, wind, etc. break the pieces into pebbles, sand and even smaller pieces. As pieces of rock accumulate, they can form another type of rock: Sedimentary rock.
