p 75-80

Rock- is a naturally formed solid that is usually made up of one or more types of minerals.

Three types of rocks:

1 Igneous

2 Sedimentary

3 Metamorphic

Essential Learning: I can identify the three different types of rocks.

Igneous rocks: forms when molten rock (magma/lava) cools and becomes solid

Sedimentary rocks: forms when pieces of older rocks, plants, and other loose materials get pressed or cemented together

Metamorphic rocks: formed when heat or pressure causes older rocks to change into new types of rocks.Rock Cycle: is the set of natural process that form, change, break down, and re-form rocks

“What’s a Rock?”

Essential Learning: I can identify the three different types of rocks.

Goto your lab table In each of the tubs, try to identify the rock type: Do this for samples 1-7 Write this

in your notebook

1 Write the name down of the sample

2 Do you see crystals or no crystals?

3 Do you see sediment, large or small or no sediment?

4 Do you see fossils?

5 Do you see bands or lines in the sample? Different colors?

6 Do you think it is Igneous, Sedimentary or Metamorphic?

Why do you think this?

Essential Learning: I can explain the rock cycle.

Essential Learning: I can explain how the rock cycle works and how it has no end.

Essential Learning:

I can identify different rock types

On page 80 answer questions 1-6 Put these in your notebook You need to finish during class Focus and get it done.

1 How are rocks and minerals different?

2 What are the three types of rocks?

3 Which rock types are most common within Earth’s crust? Which type is most common at Earth’s surface?

4 Why is the set of natural processes by which rocks change into other types of rocks called a cycle?

5 Which type of rock would you expect to be common on the floor of a large, deep lake? Why?

6 Draw a diagram showing how an igneous rock could change into a metamorphic rock and how a metamorphic rock could change into a sedimentary rock.

Essential Learning: I can explain how the rock cycle works and how it has no end.

Explain how your crayon changed from one rock

type to another and how the rock cycle can and

will continue forever and ever and ever and ever

and ever

I gneous rocks Sedimentary rocks

Essential Learning: I can explain how IGNEOUS rocks form.

p 82-87

IGNEOUS ROCK (Latin) “From Fire”

Igneous rocks: forms when molten rock cools and

becomes solid (solidifies)

Form from Magma or Lava

Essential Learning: I can explain how igneous, sedimentary, and metamorphic rocks are formed.

Texture of Igneous rock…

Intrusive Igneous rock

-Forms when magma cools within earth

-High temp allows magma to cool slowly

-Slow cooling allows time for LARGE mineral crystals to form

-Examples: Granite, Diorite, Gabbro

Extrusive Igneous Rock

-Forms when lava cools on earths surface

-The lower temp cause the lava to cool quick

-No time for mineral crystals to form

-Examples: Rhyolite, Pumice, Basalt, Obsidian

Which picture intrusive and extrusive rock?

How do you know?

How could this be?

Essential Learning: I can explain how igneous, sedimentary, and metamorphic rocks are formed.

Intrusive Granite

Extrusive Basalt

Essential Learning: I can explain how igneous, sedimentary, and metamorphic rocks are formed.

Composition of Igneous Rock p 85

SILICA- a compound of silicon and oxygen SiO2

Felsic Magma - Thick magma, high in SILICA

-Contains very little calcium, iron or magnesium

-Typically LIGHTER in color and less dense

Mafic Magma - Thin magma, low in SILICA

-Contains lots of iron, calcium and magnesium

-Typically DARKER in color and denser

Essential Learning: I can explain how igneous, sedimentary, and metamorphic rocks are formed.

Essential Learning:

I can explain how Sedimentary Rocks form from earlier rocks, minerals, animal and plant matter

p 89-95

Sedimentary Rock- rocks that form when sediments

become pressed or cemented together or when

sediments precipitate out of solution

Sediments- Materials that settle out of water or air

These can be loose pieces of rock, minerals, plant and

animal remains

How do they form? p 90

• From rock particles cementing together:

- Gravel, Sand, Silt/ClayExamples:

-Sandstone, Conglomerate, Shale

Four common steps in this formation:

1.WEATHERING AND EROSION: Break it apart

2.TRANSPORTATION: Move it along

3.DEPOSITION: Stop moving man

4.COMPACTION AND CEMENTATION: Squeeze and glue it

• From plants or shells cementing together: p 92Examples:

-Coal, Limestone FOSSILS found in these commonly

Fossils of

DEAD things COOL MAN.

• Dissolved minerals re-form from water p 93

-Minerals that crystallized as water dried up

Examples: Chemical Limestone, dolostone, rock salt

MONO LAKE, CA

Sedimentary rocks show the action of wind and water.They tell us the story about past environments.

Example: Cross Beds- Wind or water movement

Ripple Marks- Water movement commonly.Mud Cracks- Dried up lake bed

6 Fossils? Describe if present

7 How do you think if formed?

Compaction Cementation, water solution, evaporation

Metamorphic Rock p.96

Metamorphism- Process by which

existing rock is changed by

Recrystallization- Pressure and heat breaking

atoms bonds and minerals recrystallize

Metamorphic changes occur in different

areas.

• Contact Metamorphism- Small areas

- Cause Magma

• Regional Metamorphism- Large areas

-Cause Plate Movement

Essential Learning: I can explain metamorphic rocks are created

Metamorphic Rocks develop bands of minerals p 100

Foliation- arrangement of minerals in flat or wavy bands

Foliated Rocks: when mineral grains

line-up in parallel bands it is said that it has a "foliated texture"

Examples:

slate, phyllite, schist and gneiss

Essential Learning: I can explain metamorphic rocks are created

Non-Foliated Metamorphic Rocks: a metamorphic

rock where no banding occurred The grains

change, grow, and rearrange but don’t form

IF you were walking down the streets of Shakopee and you came across these rocks, what could you tell a stranger about them?

How did they form?

Use foliated and nonfoliated in your

response

One is a gneiss and on is a quartzite
