5. Essential Question I will be able to identify the three types of rock, and explain how each is formed
Standards
3c. Students know how to explain the properties of rocks based on the physical and chemical conditions in which they formed, including plate tectonic processes.

6. Section 1 Essential Questions
Identify the three major types of rock, and explain how each is formed.
Summarize the steps in the rock cycle.

7. Notes Section 10.1 Rocks and the rock cycle Three major types of rock
Magma is the parent of all rock
Three types of rocks
Three major types of rock
Igneous – formed from magma
Sedimentary – pressed or cemented together
Metamorphic – forms from heat, pressure and chemical process.
The rock cycle
Process in which rocks change form.
Not all rocks go through each stage.

8. Section 1 Essential Questions wrap up- write a short explanation of each
Identify the three major types of rock, and explain how each is formed.
Summarize the steps in the rock cycle.

9. Section 2 Essential Questions
Describe how the cooling rate of Magma and lava affects the texture of igneous rock.
Classify igneous rocks according to their mineral composition.
Describe a number of identifiable igneous rock structures.

10. Notes Section 10.2 Igneous rock Texture of igneous rock
2 groups intrusive and extrusive
Crystalline size determines the grouping.
Texture of igneous rock
Intrusive has a coarse grain texture.
Slow cooling allows large crystal structures
Extrusive has a fine grain texture
Faster cooling allows for smaller crystal structures
Silica-rich magma forms obsidian.
Porphyritic
Composition of igneous rocks
Chemical composition determines rock family – Felsic, intermediate, Mafic
Felsic has a light color in main mineral.
Mafic has low amounts of silica, dark in color
Intermediate family has less quartz and a medium color.

11. Notes Section 10.2 Igneous rock structure Intrusions
Intrusion – underground
Extrusions – on surface
Intrusions
Batholiths are the largest of all intrusions.
A stock is an intrusion that covers less then 100 sq. KM
Laccolith is what forms dome mountains.
Sill are harden magma between layers of rock and lies horizontal.
A dike is when magma pushes up through fissures to the surface

12. Notes Section 10.2 Extrusions Erupts on the surface Forms a volcanoes
When it erupts onto the surface from cracks it can form a lava plateau.
Forms a volcanoes
The central vent of a volcano is the volcanic neck.

13. Section 2 Essential Questions wrap up- write a short explanation of each
Describe how the cooling rate of Magma and lava affects the texture of igneous rock.
Classify igneous rocks according to their mineral composition.
Describe a number of identifiable igneous rock structures.

14. Section 3 Essential Questions
Name the three types of sedimentary rock and give an example of each
Describe several identifiable sedimentary rock features

15. Notes Section 10.3 Sedimentary Rock Formation of Sedimentary Rocks
Made in two ways: Compaction & cementation
Compaction is when overlying layers press down and push out the air and water.
Cementation is when minerals are left behind to bind the fragments together.
Classified by the kind and size of fragments.
Formation of Sedimentary Rocks
Clastic sedimentary rocks are run off water, wind or ice.
Chemical sedimentary rocks are precipitated from water.
Organic sedimentary rocks form from the remains of organisms.

16. Notes Section 10.3 Clastic Sedimentary Rocks
Rounded gravel or pebbles are a conglomerate.
If the fragments have sharp corners it is breccia.
Sand size or sandstone have pores that allow water and oil to flow through.
Shale is made of clay sized materials.
Chemical Sedimentary Rocks
Rocks that are formed from minerals that were once in water, it settles and solidifies.
Evaporites are when the water evaporates and leaves the minerals behind. (salts)

17. Notes Section 10.3 Organic sedimentary rocks Sedimentary rock features
Are formed from what used to be a living organism.
Coal (plants), limestone & chalk (sea life) are examples.
Sedimentary rock features
Stratification, ripple marks, mud cracks, fossils and concretions.
Stratification
This is the layering of the sediments, flowing water makes smooth layers and wind makes a crossing pattern.
Graded bedding is when the size of materials causes the layering.

18. Notes Section 10.3 Ripple marks and mud cracks Fossils Concretions
Ripple marks are formed by water or winds
Mud cracks form when the mud dries and shrinks, it then is later covered by sediment again.
Fossils
Are found in sedimentary rocks, they are covered by the sediment.
Concretions
Are deposits that build up in cracks or openings in the sedimentary rock
Sometimes crystals grow and form a geode.

19. Section 3 Essential Questions wrap up- write a short explanation of each
Name the three types of sedimentary rock and give an example of each
Describe several identifiable sedimentary rock features

20. Section 4 Essential Questions
Distinguish between regional and contact metamorphism
Distinguish between foliated and non foliated rocks and give an example of each

21. Notes Section 10.4 Metamorphic Rock Formation of Metamorphic Rocks
Formed by heat, pressure and chemical process deep inside the earth.
Formation of Metamorphic Rocks
Caused by heat, pressure and hot fluids.
It can change in size and shape or separate into parallel bands.
2 types; Contact metamorphism and regional metamorphism.
Contact is when the rock is near magma or the hot fluids.
Regional is caused in the areas of plate movement.

22. Notes Section 10.4 Classification of metamorphic rocks Foliated rocks
Foliated and Nonfoliated
Foliated has mineral bands
Nonfoliated does not
Foliated rocks
Form in two ways; extreme pressure may flatten the crystals into mineral bands or they may separate by density into dark and light bands.
Nonfoliated rocks
Do not have bands, the heat and pressure cause the rock to recrystallize so the spaces disappear.

23. Section 4 Essential Questions wrap up- write a short explanation of each
Distinguish between regional and contact metamorphism
Distinguish between foliated and non foliated rocks and give an example of each
