  1. New Homework Reward! • For completing your homework and being at school every day of a week, you will get a certificate • You will also get to put a sticker up on the back wall • 4 stickers = free homework pass • Whole class gets to 10 stickers = free hour of class!

  2. ROCKS Brian Madison: You remember that spelling bee you won in the 1st grade? Billy Madison: Oh no, you didn't. Brian Madison: Rock? "r-o-k"? Billy Madison: Yea, so what's your point? Brian Madison: r-o-C-k! Billy Madison: Ohh! The "C" is silent.

  3. IGNEOUS ROCKS:forms when magma coolscrystals form during cooling

  4. Two types of Igneous Rocks Intrusive Extrusive

  5. Intrusive • Magma cools SLOWLY below Earth’s Surface • LARGE visible crystals • Large crystals have time to form because the cooling process is slow because it is very warm closer to the mantle

  6. Intrusive Igneous: Granite

  7. Where would intrusive igneous rock likely be found? • Inside or below a volcano • In the mantle

  8. Extrusive • Magma cools RAPIDLY above Earth’s surface • Has SMALL microscopic crystals • Crystals do not have time to form (because cooling happens very quickly) so they’re very small

  9. Extrusive Igneous: Basalt

  10. Where would extrusive igneous rock likely be found? • Outside of a volcano • In ridges!

  11. SEDIMENTARY ROCKS • Form when old pieces of rocks have been weathered and combined to make a new rock

  12. Sedimentary Rocks • Formed via 4 step process: • 1. Weathering—wind, rain, and chemicals decompose the rocks • 2. Erosion—Pieces of rock moved by wind or water • 3. Deposition—Pieces dropped in new location • 4. Sedimentation—Pieces compressed and cemented together • So, sedimentary rocks are formed where weathering occurs! • On the surface of the earth and near water

  13. Sedimentary Rocks: Imp Point • As sediments continue to stack on top of each other, LAYERS will be formed in the rock • Therefore, sedimentary rocks contained LAYERS called strata

  14. Layers of Sedimentary Rock • The layers that were deposited first will be on the bottom. • So, oldest layers of rock are on the bottom and the newest layers of rock are on the top • Layers of rock can be dated and can tell us a lot of information about the conditions and the species the lived when that rock was deposited • Fossils are often found in layers of sedimentary rock

  15. This picture shows layers of rock on earth. You can see that the deepest layers contain the oldest fossils

  16. Which layer here is the oldest? The newest? Answer: • Kaibab Formation is oldest • Dakota Formation is newest

  17. Rock Layers of the Grand Canyon

  18. Sedimentary Rocks • Sandstone

  19. Sedimentary Rock • Limestone

  20. Sedimentary Rock • siltstone

  21. Metamorphic Rocks • Created when other rocks (sedimentary or igneous) are changed by heat and pressure • Found at / near subduction zones because this is where crust (rock) is pushed downward to areas of heat and pressure!

  22. METAMORPHIC ROCKS

  23. Metamorphic Rocks • Quartzite

  24. Metamorphic Rocks • Marble
