1 Day 5 Daily Warm-Up Exercises How do igneous rocks form? Igneous rocks form when molten rock (magma or lava) cools and hardens. How do metamorphic rocks form? Metamorphic rocks form when an existing rock changes due to heat and/or pressure.

2 Igneous and Metamorphic Rocks (Part 1, steps 1-6) Investigation 8 One Rock to Another

3 Rock Identification A and B Using the hand lens and the acid, complete the Rock number and Description columns. Use Resource Book pages

4 Rock Identification A (# ) 11 pink, white, black, grey shiny flat crystals dense intrusive igneous granite 12 grey, black, white dense fine-grained extrusive igneous basalt, fine-grained 13 black, grey holes of various sizes dense extrusive igneous basalt, vesicular

5 Rock Identification A (# ) 16 black, dark brown very shiny, like glass forms sharp edges extrusive igneous obsidian 17 grey, tan with holes not very dense would float in water extrusive igneous pumice 19 browns, reds holes like pumice does not float in water extrusive igneous scoria

6 Rock Identification A (#21) 21 mostly white, some tan chalky, grainy extrusive igneous tuff

7 Rock Identification B (#1 - 15) 1 black, shiny comes from shale or mudstone metamorphic schist 14 white, tan, black with lines comes from shale or granite metamorphic gneiss 15 fizzes in acid white, crystalline comes from limestone marble metamorphic

8 Rock Identification B (# ) 18 pink, crystalline comes from sandstone metamorphic quartzite 20 black, hard, smooth comes from shale metamorphic slate
