### Understanding the Rock Cycle and Types of Rocks ###

DESCRIPTION

This educational resource covers the formation and characteristics of the three major types of rocks: igneous, sedimentary, and metamorphic. Learn how igneous rocks form from molten magma and lava, the processes of weathering and erosion that shape sedimentary rocks, and the transformation of rocks under heat and pressure in metamorphic processes. The notes also include the distinctions between intrusive and extrusive igneous rocks, and the processes of compaction and cementation in sedimentary rock formation. Discover the significance of each type and their role in the geological rock cycle. ###

  1. Ch 3 Notes Mr. Russo Beaumont High School

  2. Ch 3 Vocab Matrix – Pg 30 • Igneous Rock • Lava • Magma • Weathering • Sediments • Sedimentary Rock • Metamorphic Rock • Intrusive Igneous • Extrusive Igneous • Erosion • Compaction • Cementation

  3. Objective – Notes Ch 3.1(Pg 32) • We will be able to describe how the 3 major types of rocks are formed

  4. Rock • Rock – A solid mass of mineral or mineral like matter that occurs naturally

  5. What are the 3 major types of rocks? • Igneous • Sedimentary • Metamorphic

  6. Igneous Rock • Igneous Rock – Igneous rock forms when molten rock (magma/lava) cools and becomes solid

  7. Magma • Magma – Molten rock below the surface

  8. Lava • Lava – Molten Rock above the surface

  9. Weathering / Sediments • Weathering – When rocks are broken down to bits and pieces • Sediments – The bits and pieces that occur due to weathering

  10. Sedimentary Rock • Sedimentary Rock – Rock that forms from sediments being compacted or cemented together

  11. Metamorphic Rock • Metamorphic Rock – Forms under intense heat and pressure

  12. Rock Cycle • Rock Cycle – The cycle that shows how rocks change from one type to another. • TAKES A VERY LONG TIME

  13. What powers the Earth’s Rock Cycle? • Igneous / Metamorphic Rock form due to the heat from the INTERIOR OF THE EARTH. • Sedimentary Rock forms due to weathering which is caused by THE SUN

  14. Objective – Notes 3.2 (Pg 35) • We will be able to describe the characteristics that differentiate intrusive and extrusive igneous rocks

  15. What does the Latin word “ignis” mean? • Ignis means Fire • Igneous rock comes from molten lava or magma (very hot)

  16. Intrusive Igneous • Intrusive Igneous – Rocks that cool or harden below the surface. • Common Example - Granite

  17. Extrusive Igneous • Extrusive Igneous Rocks – Rocks that cool or harden above the surface • Common Example - Rhyolite

  18. Question • Does magma form an extrusive or intrusive igneous rock? • Intrusive • Does lava form an extrusive or intrusive igneous rock? • Extrusive

  19. Characteristics - Igneous

  20. What igneous rock is made of magma? • How fast does intrusive rock cool? • What is the texture of a extrusive igneous rock?

  21. How does the rate of cooling affect the texture? • Cools very slow – Rough texture(coarse-grained) • Cools very fast – Smooth texture (fine-grained)

  22. Objective – Notes 3.3 (Pg 39) • We will be able to describe the relationship between compaction, cementing, clastic and chemical sedimentary rocks.

  23. Ch 3.3Erosion • Erosion – Weathering and removal of rock • Water, wind, ice, gravity

  24. Deposition • Deposition – When rock sediment is deposited into a new area • Largest sediments deposit first • Small sediments deposit last

  25. Compaction • Compaction – A process that squeezes or compacts sediments

  26. Cementation • Cementation – When dissolved minerals are deposited in the tiny spaces among the sediments (sediments are glued together)

  27. Clastic Sedimentary Rocks • Clastic sedimentary Rock – made of weathered bits of rock and minerals

  28. Chemical Sedimentary Rocks • Chemical Sedimentary Rock – Dissolved minerals become solid in water

  29. Are clastic sedimentary formed by compaction or cementing? Chemical sedimentary? • Clastic Sedimentary Rock – Compaction • Chemical Sedimentary Rock - Cementing

  30. What is unique of sedimentary rocks? • They give us clues to how, when and where the rock formed. • Bottom layers are the oldest layer • Top layer is the youngest layer

  31. What is unique of sedimentary rocks? • Fossils are only found in sedimentary rocks.

  32. Objective: 3.4 Notes (pg 42 ) • We will be able to describe the 2 types of metamorphic rocks and how they form

  33. Ch 3.4Metamorphism • Metamorphism – Existing rocks change by heat and pressure • Metamorphic rocks look much different than parent rock

  34. Where does most metamorphism take place? • High temperatures and pressure • A few kilometers (miles) below the surface

  35. Contact Metamorphism • Contact Metamorphism – Hot magma moves into rock

  36. Regional Metamorphism • Regional Metamorphism – Large scale deformation – mountain building

  37. What are the 3 agents of metamorphism? • Heat • Pressure • Hydrothermal solutions (Very hot liquids)

  38. Foliated metamorphic rocks • Foliated metamorphic Rocks – Metamorphic rocks with a layered or banded appearance

  39. Non-foliated metamorphic rocks • Non-foliated metamorphic rock – A metamorphic rock that does not have a banded texture. Ex-marble
