1. C HAPTER 6, S ECTION 1 Standards 3c. Students know how to explain the properties of rocks based on the physical and chemical conditions in which they are formed, including plate tectonic properties. Objective 1 Identify the 3 major types of rock, and explain how each type forms. Objective 2 Summarize the steps in the rock cycle. Assessment Rock Cycle Poster Review Daily Bellwork, Science Starters, Standards Practice

2. K EY T ERMS Create a flash card for the following key terms (p. 125 in textbook):  Rock Cycle If you finish early, study your flash cards!

3. 3 M AJOR TYPES OF R OCK Igneous Sedimentary Metamorphic

4. B RAIN P OP T YPES OF R OCK

5. I GNEOUS R OCK Igneous rocks form when magma (molten rock) cools and hardens. Magma is called lava when it is on the Earth’s surface.

6. S EDIMENTARY R OCKS Wind and water break down all types of rocks into small fragments over time. These broken bits are called Sediment. Sediment is carried away and deposited by water, ice, and wind. When sediment deposits are compressed together and they harden they are called Sedimentary Rocks.

7. M ETAMORPHIC R OCKS Tremendous Pressure, extreme heat, and chemical processes can change the form of existing rock. The rock that forms when existing rock changes is called metamorphic rock.

8. QUICK CHECK!! 1. What are the 3 types of rock? ____________________________________________ ____________________________________________ ____________________________________________ 2. Choose 1 type of rock and describe how it forms: ____________________________________________ ____________________________________________ ____________________________________________ ____________________________________________ ____________________________________________

9. INTERACTIVE! Create a 3 section flap book, one flap for each type of rock: Igneous, Sedimentary, Metamorphic. Under each flap include a written description/definition (in your own words) and a picture. Add color! Tape into your notebook when complete.

10. T HE R OCK C YCLE Any of the 3 types of rock can be changed into one of the other types of rock. Geologic forces cause the rocks to change…this is called the ROCK CYCLE.

14. T HE R OCK C YCLE E XAMPLES When an igneous rock is exposed on the surface wind and water can break it down into sediment. This sediment is carried away and eventually compacted over time. It becomes Sedimentary rock. Then it may be exposed to extreme heat or pressure and become metamorphic rock. Finally it may melt and become magma and the cycle will start over. A specific rock may not go completely through the rock cycle, it may only pass through one or two types of rock or go in a different order.

15. INTERACTIVE! On the white paper, illustrate the rock cycle. See page 126 for an example or the pic below. When complete tape into notebook. Note: Really well-done illustrations will be put up in classroom.

16. B OWEN ’ S R EACTION S ERIES Geologist N.L. Bowen summarized the order in which minerals crystallize from magma to solid rock.

In your own words explain the rock cycle: ____________________________________________ ____________________________________________ ____________________________________________ ____________________________________________ ____________________________________________ ____________________________________________ ____________________________________________ ____________________________________________

19. A SSESSMENT The Life Cycle of a Rock…Poster In table groups design a poster that illustrates the rock cycle. Be creative! Be accurate! Label everything!
