  1. Bell Work 9/20/13 What do you know about ROCKS??? I want 5 complete sentences about rocks… • Rocks are…. • Rocks are…. • Rocks are…. • Rocks are…. • Rocks are…. • On your desk you should have: • Agenda (opened to PRIDE card) • Interactive Notebook • Pencil/Pen

  2. TABLE OF CONTENTS 8/8/13 Interactive Notebook Introduction 7 Chemistry 9 Minerals 17 9/20/13 The Rock Cycle ??

  3. The Rock Cycle

  4. What is the difference between a rock & a mineral? • Minerals are solid, inorganic, naturally occurring, and have a fixed crystalline structure made of one or more elements. • A rock is a naturally occurring solid mixture of one or more minerals and organic matter.

  5. The Value of Rocks • Rock is an important natural resource. • Rocks can be made into: • Hammers • Arrowheads • Spear points • Knives • Scrapers • Buildings • Monuments • Roads

  6. How do we classify rocks?? You decide!!! Create a Circle Map in your interactive notebook describing how you would classify these rocks!

  7. How do we classify rocks?? Rocks are classified by how their Formation, Composition, and Texture.

  8. 3 Types of Rocks… that’s it?? • Igneous Rocks • Sedimentary Rocks • Metamorphic Rocks Raise your hand if you recycle: Paper, plastic, aluminum… The Earth recycles too!!! One thing it recycles is ROCK!

  9. Bill Nye the Science GuyVideo: Weathering and Rocks http://www.youtube.com/watch?v=9Xv1DoqkARQ OUTPUT: 5 AWESOME facts (complete sentences)

  10. Rock Cycle Video • http://www.youtube.com/watch?v=CvDw07iYaJQ Follow along in the video and answer the questions!!!

  11. Bell Work 9/23/13 • On your desk you should have: • Agenda (opened to PRIDE card) • Interactive Notebook • Pencil/Pen • 1. What is a ROCK?? • A naturally occurring solid • mixture of one or more • minerals and organic matter. • 2. What are the three types of rocks? • Sedimentary • Igneous • Metamorphic

  12. The Rock Cycle The continual process by which new rock forms from old rock material

  13. 3 Highlighters! • Each rock type • Force or Process acting on the rock types • Environmental features

  14. Bell Work 9/24/13 • On your desk you should have: • Agenda (opened to PRIDE card) • Interactive Notebook • Pencil/Pen 1. Describe how an extrusive igneous rock becomes an sedimentary rock.

  15. Draw and explain your own Rock Cycle!

  16. Bell Work 9/25/13 • On your desk you should have: • Agenda (opened to PRIDE card) • Interactive Notebook • Pencil/Pen • Rock Cycle Diagram and Explanation • What is lithification? • Compaction and cementation of sediment together • Which type of rock is formed through lithification? • Sedimentary Rock • How is metamorphic rock formed? • Heat and pressure change sedimentary rock into metamorphic rock. Rock Cycle SONGS!! http://www.youtube.com/watch?v=r68iEwYdbh4 http://www.youtube.com/watch?v=rkGVE6wNAzo

  17. Processes that Shape the Earth • Weathering • Picture (front) • Definition • Why is it important? • Deposition • Picture (front) • Definition • Where is sediment deposited? • What happens after deposition? • Erosion • Picture (front) • Definition • What moves the sediment?

  18. Bell Work 9/26/13 • On your desk you should have: • Agenda (opened to PRIDE card) • Interactive Notebook • Pencil/Pen • How are weathering and erosion different? Weathering is the breakdown of rock into sediment due to the sun, wind, and rain whereas erosion is the movement of sediment from one place to another. • What is deposition? Deposition is the process in which sediment is laid down.

  19. Processes that Shape the Earth • Weathering • Picture (front) • Definition • Why is it important? • Deposition • Picture (front) • Definition • Where is sediment deposited? • What happens after deposition? • Erosion • Picture (front) • Definition • What moves the sediment?

  20. Igneous Rocks • Where do Igneous rocks come from?? • ……VOLCANOES! • Temperatures deep within the Earth are hot enough (14000F to 23000F) to melt rock

  21. Igneous Rocks • Intrusive igneous rock- Forms when magma cools within the Earth • Extrusive igneous rock- Forms when lava cools on Earth’s surface

  22. Textures of Igneous Rocks • Texture = size of the rock’s mineral crystals • Large crystals- slow cooling time • Intrusive rocks commonly have large crystals • Small/No crystals- fast cooling time • Extrusive rocks commonly have small or no crystals

  23. Textures of Igneous Rocks • Large Crystals • Small/No Crystals

  24. Ship Rock • Formed 1km below Earth’s surface • It was once intrusive igneous rock • It is what’s left behind of magma that once fed a volcano • Through weathering and erosion, surface rock has been worn away… • …Ship Rock survives because igneous rock is usually harder than other types of rocks

  25. Quick Quiz What causes igneous rocks to have different textures?

  26. Bell Work 9/27/13 • On your desk you should have: • Agenda (opened to PRIDE card) • Interactive Notebook • Pencil/Pen 1. How are igneous rocks with large crystals formed? 2. How are Igneous rocks with small or no crystals formed?

  27. Sedimentary Rocks • Form from sedimentsthat undergo lithification (get compacted and cemented together into rock) • Sediments- Can be pieces of rocks, minerals, plants, or animals

  28. Sedimentary Rock Formation • Rainwater washes away rock particles… • Flow downhill to streams and rivers… • Eventually these sediments reach the ocean… • Settle on the bottom of the ocean… • Pressure eventually forces these sediments together… • Sedimentary rock is formed!

  29. Organic Sedimentary Rocks • Coal- • Made up of remains of plants (dead wood, bark, leaves, etc.) • Started forming millions of years ago • Limestone- • Made up of remains of ocean organisms (shells, bones, etc.) • Pressure “squishes” these materials together into rock

  30. Limestone Towers (Mono Lake) • Minerals can dissolve in water … • …and then re-form as the water evaporates • Often they form underwater and become visible as the water level drops.

  31. Metamorphic Rock • Forms when heat or pressure cause older rocks to change into new types of rocks • Metamorphism- • The process in which existing rock is changed by heat or pressure

  32. Metamorphic Rock • During metamorphism rocks undergo many changes • Heat and pressure can break the bonds that join the atoms in minerals… the atoms then join together differently • Recrystallization • Rocks do not melt during this process!!!

  33. Textures • Foliation- An arrangement of minerals in flat or wavy parallel bands Foliated Rocks • Develop under pressure • Minerals flatten out or line up in bands Nonfoiated Rocks • Develop if rock is made up of only one type of mineral • May not be under enough pressure

  34. Quick Quiz Foliated or Nonfoliated?? Saglet Fiord, Canada

  35. What type of rock is this?How do you know??
