Difference Between Rocks and Minerals

Difference Between Rocks and Minerals. Physical Properties of mineral are the same throughout Physical Properties of rocks vary from one part of the rock to another. Rocks are classified according to origin (where and how it formed) either: Igneous, Metamorphic, or Sedimentary.

  1. Difference Between Rocks and Minerals

  2. Physical Properties of mineral are the same throughoutPhysical Properties of rocks vary from one part of the rock to another

  3. Rocks are classified according to origin (where and how it formed)either: Igneous, Metamorphic, or Sedimentary

  4. Minerals are classified according to their chemical composition and the arrangement of their atoms

  5. IGNEOUS ROCKSFOLLOWS WORKSHEET(GET OUT WORKSHEET)

  6. Igneous rock is rock formed by the cooling and hardening of molten rock

  7. Synonyms for SolidificationCrystallization& Hardening

  8. Magma- liquid rock beneath the earth’s surface

  9. Lava- Liquid rock that has reached the Earth’s surface

  10. The only difference between magma and lava is LOCATION

  11. The solid grains or pieces of mineral that form when molten rock cools and hardens are called CRYSTALS

  12. If a rock has only one kind of mineral crystal it is called MONOMINERALLIC

  13. If a rock has more than one kind of mineral crystals it is called POLYMINERALLIC

  14. Monominerallic vs. Polyminerllic(Will Draw on Board)

  15. SIZE OF MINERAL CRYSTALS

  16. Large crystals form deep within the Earth. Small crystals form close to the Earth’s surface

  17. The faster the cooling the SMALLER the crystals, or the slower the cooling the LARGER the crystals

  18. INTRUSIVE IGNEOUS ROCK

  19. INTRUSIVE IGNEOUS ROCKA rock formed by cooling magma below the surface

  20. INTRUSIVE IGNEOUS ROCKCooled SLOW

  21. INTRUSIVE IGNEOUS ROCKContains LARGE crystals or grains

  22. INTRUSIVE IGNEOUS ROCKFormed INSIDE THE EARTH from MAGMA

  23. EXTRUSIVE IGNEOUS ROCK

  24. EXTRUSIVE IGNEOUS ROCKA rock formed by cooling lava on the surface

  25. EXTRUSIVE IGNEOUS ROCKcooled FAST

  26. EXTRUSIVE IGNEOUS ROCKContains SMALL Crystals or Grains

  27. EXTRUSIVE IGNEOUS ROCKFormed on the surface of the Earth from lava

  28. TEXTUREFancy name for Crystal size or how the surface feels

  29. Coarse Texture mean LARGE CRYSTALS

  30. Fine texture meansSMALL CRYSTALS, makes it more difficult to identify

  31. Glassy Texture means very rapid cooling resulting in no crystalsex. Obsidian

  32. PUMICE- type of lava rock, rough surface with very low density, cooled rapidly trapping in gasses
