  1. Rock Cycle Classifying rocks

  2. In Class 3-2-12 • Obj. I will be able to classify rocks as metamorphic, igneous, or sedimentary by the processes of their formation • Vocabulary • Cementation • Compaction • Deposition • Erostion • Foliated • Igneous rock • Lava • Lithification • Magma • Metamorphic rock • Non-foliated • recrystallization • Sedimentary rock • Sedimentation • weathering

  3. @Home • Study vocabulary • Visit stemscopes online • Laporteisd.stemscopes.com • Auguste • science

  4. Vocabulary notes • cementation - A process whereby compacted sediments bind and stick together and turn into rock

  5. compaction - A process whereby sediments pack, crush, and settle under the action of gravity and pressure from overlying layers

  6. deposition – the dropping off of eroded materials in a new location

  7. erosion– the process of moving sediments by wind, water, ice and gravity

  8. foliated – rocks that are composed of thin easily separable layers or bands

  9. igneous rock - Rock formed when heated magma or lava cools and hardens

  10. lava - A result of molten rock material pushed to Earth’s surface by volcanic action

  11. lithification - The compaction and cementation of sediment into rock.

  12. magma - Melted rock material beneath Earth’s surface

  13. metamorphic rock - Rock deep within Earth’s crust that has been exposed to extreme heat and pressure causing changes to its appearance, structure, and composition

  14. non-foliated – rocks that do not have a layered or banded structure.

  15. recrystallization - A reaction in which the atoms of existing crystals within a rock are reorganized due to heat and/or pressure.

  16. sedimentary rock - Rock formed when sediments deposited in layers, compact and cement together under pressure, over long periods of time

  17. sedimentation - The act or process of depositing sediment.

  18. weathering – the process of breaking rocks down into sediments

  19. - • Extrusive rocks- Formed when molten rock reaches the Earth’s surface and cools.

  20. Intrusive rock- Formed when magma cools underground forming rock
