1. Catalyst  In your folder, make a new divider for UNIT 2 the LITHOSPHERE and ROCK CYCLE

2. Catalyst  On a sticky note:  What is a rock?  How would you categorize a rock?  Why are rocks important? They don’t have life so why do we care about them?

3. Agenda  Notes – The Lithosphere  Rock Cycle Coloring Activity  Exit Ticket

4. I can explain the rock cycle. The Lithosphere and Rocks

5. Geology and Geologists  Geology- the study of solid Earth; the rocks it is composed of and the processes by which they change  Geologists- a scientist who studies the solid and liquid matter that constitutes the Earth as well as the processes and history that have shaped it

6. The Lithosphere  Lithosphere = outer surface of the Earth  The Earth is made up of Four layers. crust mantle inner core outer core

7. Layers of the Earth  The crust is the thinnest layer on the outside. It is the coolest layer of the earth.  Water and dirt Aka PLATES  The mantle is the second layer of earth and is hotter than the crust.  Convection currents Flows (liquid like) Moves the crust

8. Layers of the Earth  The outer core is the third layer of the earth. It is hotter than the mantle  Liquid METALS (nickel and iron)  The inner core is the hottest layer of the earth, and in the center of the earth.  Solid METAL

9. Layers of the Earth  Lithosphere = crust and upper mantle  earth’s tectonic plates  Asthenosphere = below the Lithosphere in the mantle

10. Layers of the Earth http://www.teachertube.com/viewVideo.php?video_i d=244331&title=Layers_of_the_Earth_song SING ALONG!!!

11. ROCKS

12. Rocks  Weathering – break down of large rock into small pieces or sediments  Erosion – movement of sediments from one spot to another Wind, water  Sediments – small pieces of rock  Deposition – sediments settle to the bottom  Foliation – many layers of metamorphic rock Caused by pressure

13. ROCKS  Sedimentary – formed from sediments (parts) of sand, shells, pebbles, and larger rocks  Light pressure  Fossils Conglomerate

14. Sedimentary Deposition Cementation Compaction

15. ROCKS  Metamorphic – formed underneath the earth’s surface from EXTREME heat and pressure

16. Metamorphic  Foliated  Grains arranged in parallel layers  Non-foliated  Grains randomly arranged

17. ROCKS  Igneous – forms when magma cools and hardens

18. Igneous  Intrusive  Magma hardened beneath the Earth  Forms slowly causing the rocks to be coarse grained  Extrusive  Lava erupted rocks  Forms quickly causing the rocks to be fine grained Granite Obsidian

26. Review Exit Ticket 1. Which condition is necessary for metamorphic rocks to form? A. constant weathering and erosion B. extreme pressure and heating C. rapid burial of sediments D. slow cooling of magma

27. Review Exit Ticket 2. The sediments found in a riverbed are most likely a result of which action on nearby rocks? A. Heat B. Faulting C. Pressure D. Weathering

28. Review Exit Ticket 3. Which of these statements best describes the rock cycle? A. Layers of rock are broken by faults B. Rocks in the ocean become rocks on land C. Lunar rocks change into terrestrial rocks D. New rocks form from older rocks

29. Review Exit Ticket 4. How are sedimentary rocks made? A. Magma or lava is cooled B. Materials are pressed together C. Chemical reactions change minerals D. Earthquakes cause small pieces to fall

30. Review Exit Ticket 5. Overtime, dried lava from an old volcano is worn down and broken into small pieces. When these pieces pile up and are cemented together to form new rock, how would this new rock be classified? A. Magma B. Igneous C. Sedimentary D. Metamorphic

42. The Life Cycle of a ROCK!  7 stations around the room, students work INDIVIDUALLY  Pick a starting location, roll the die and RECORD WHAT THE DIE SAYS on the worksheet.  Move to wherever the die says (MAY STAY AT STATION!)  Move around until students has completed the Life Cycle of a Rock Create a cartoon of the rock’s journey!
