6th Grade Ch. 4 Sec. 2 How Minerals Form

  1. 1. Ch. 4 Sec. 2Ch. 4 Sec. 2 How MineralsHow Minerals FormForm
  2. 2. geode •rounded hollow rock lined w/ mineral crystals
  3. 3. crystallization • process by which atoms are arranged to form material w/ crystal structure
  4. 4. 2 ways minerals can form crystallization of melted materials (magma or lava cools) crystallization of materials dissolved in water (evaporation)
  5. 5. minerals from magma factors that affect crystal size rate at which magma cools amount of gas magma contains chemical composition of magma slow cooling large crystals rapid cooling small crystals • hot magma or lava cools  forms crystals
  6. 6. solution •mixture in which one substance dissolves in another
  7. 7. magma heats water underground
  8. 8. minerals formed by evaporation • water evaporates from solution leaving crystals of minerals
  9. 9. These huge selenite crystals in a cave in Mexico formed from the crystallization of minerals in a solution.

  13. 13. geode •rounded hollow rock lined w/ mineral crystals
  14. 14. crystallization • process by which atoms are arranged to form material w/ crystal structure
  15. 15. How do minerals form from magma and lava? Minerals form as hot magma cools inside the crust, or as lava hardens on the surface. When these liquids cool to a solid state, they form crystals.
