2 Essential Questions: What processes are involved in the formation and classification of metamorphic, sedimentary, and igneous rocks?
3 Rock Cycle Rock Cycle Sediments SedimentaryIgneous Rock Metamorphic Sedimentary Rock Cycle A model that describes the formation, breakdown, and reformation of a rock. Magma © KeslerScience.com
4 Rock Cycle Ex. sandstone, limestone Sedimentary RockFormed when sediments accumulate and compact and cement together. Often deposited in layers and contain sand, pebbles, and frequently fossils. Ex. sandstone, limestone If you have rock samples on your lab this would be a great time to pass them around. © KeslerScience.com
5 Physical properties of Sedimentary RocksRock Cycle Physical properties of Sedimentary Rocks Sand, pebble, and even boulder size particles Some may contain fossils © KeslerScience.com
6 Quick Action – How Are Rocks Broken Down?Discuss and Be Prepared to Share: Face Partner Try to come up with 5 ways which rocks can be broken down into smaller pieces (sediment)? Pass examples of sedimentary rocks around the class for students to see. © KeslerScience.com
7 Rock Cycle By what process are sedimentary rocks broken down? Weathering By weather (rain, ice, wind), chemical changes, and living things (plant). Creates lose material called sediments. © KeslerScience.com
8 Erosion Rock Cycle By what process are sediments moved? Wind WaterGravity Ice They are deposited in layers - Deposition © KeslerScience.com
9 Rock Cycle What are the processes that form sedimentary rock? Compaction Sediments are deeply buried, placing them under pressure because of the weight of overlying layers. © KeslerScience.com
10 Cementation Rock CycleWhat are the processes that form sedimentary rock? Cementation New minerals stick the sediment together just like cement. This holds the grains together tightly. © KeslerScience.com
11 Quick Action – Rock CycleSedimentary Processes Add to your notes Weathering and Erosion (A) Compaction and Cementation (B) Sediments B. Sedimentary Rock A. A. A. Igneous Rock Metamorphic Rock Pass examples of sedimentary rocks around the class for students to see. Magma © KeslerScience.com
12 Rock Cycle Metamorphic RockFormed by heat and pressure while buried deep below Earth’s surface. Have a layered or banded (ribbon like) appearance or may have crystals. Ex. Gneiss, Marble, Slate Pass around samples of metamorphic rock. © KeslerScience.com
13 Physical Properties of Metamorphic RocksRock Cycle Physical Properties of Metamorphic Rocks Layers look like ribbons Crystals © KeslerScience.com
14 Heat (caused by magma) Rock CycleWhat are the processes that form metamorphic rock? Heat (caused by magma) Temperatures high enough to change its structure but not to melt it. Heat can change sedimentary, igneous, or another older metamorphic rock. © KeslerScience.com
15 Rock Cycle What are the processes that form metamorphic rock? Pressure - Caused by intense collisions and friction of tectonic plates and pressure from overlying rock layers. Deep under the Earth’s surface. Pressure can change sedimentary, igneous or another older metamorphic rock. © KeslerScience.com

17 Igneous Rock Rock Cycle Formed when lava or magma harden.Found near volcanoes or fissures Ex. Basalt, Obsidian, Granite © KeslerScience.com
18 Rock Cycle Physical Properties of Igneous rockFast Cooling Slow Cooling Glassy Large crystals Holes where gas was trapped Many colors © KeslerScience.com
19 Melting Rock Cycle What are the processes that form Igneous rock?Caused by increase in temperature in rock deep below the surface of Earth Caused by friction between crustal plates Lava –molten rock material on Earth’s surface. Magma – molten rock material under Earth’s surface. © KeslerScience.com
20 Cooling and Hardening Rock CycleWhat are the processes that form igneous rock? Cooling and Hardening Melted rock turns solid. Slow cooling happens below Earth’s surface as magma cools forming large crystals. Ex. granite Fast cooling happens on the Earth’s surface as lava cools forming small crystals. Ex. obsidian, basalt, pumice © KeslerScience.com

22 Quick Action – INB TemplateTitle INB Template Cut out the template along dark lines. Do not cut along dashed lines. Glue along the thin tab and place in INB. Fill in how each is formed, characteristics, and examples. You can use this INB template or the next one. Your choice. Both cover the same information. © KeslerScience.com
