Understanding Earth's Layers and Rock Types Through Interactive Learning

On September 29-30, 2008, we delved into the fascinating world of geology, focusing on the layers of the Earth and rock types. Activities included reviewing the rock lab, completing USGS readings, and taking quizzes on Gizmos. We also made delicious inferences about rock types using candies to represent igneous, metamorphic, and sedimentary rocks while discussing their characteristics. A quiz on the basic layers of Earth was also held, along with exercises on convection currents and the differences between oceanic and continental crust.

Presentation Transcript

  1. September 29, 2008 Today we will:

  2. 1st period • Review rock lab • Complete USGS reading • Complete 3 gizmo quizzes • Rockhound! (rock creations, “quiz”) • Rockhound Home Page • Notes if time allows…layers of the earth

  3. 3rd PERIOD • Review rock lab • Finish packet work • Gizmo quizzes • Rock hound • Rockhound Home Page

  4. 4TH AND 7TH PERIOD • Gizmo lab • Complete 3 gizmos • Rockhound • Rockhound Home Page

  5. September 30, 2008 • Today we will: • Make an inference referencing the picture • Devils Tower National Monument - Wikipedia, the free encyclopedia • Show you the rock hound website • Review packet work • Eating activity • Review for test on rocks • Start layers of the earth • Homework: chapter 3 test tomorrow!!!

  6. What does each represent and why? • Hershey kiss: • Igneous melts in your mouth • Starburst: • METAMORPHIC • heat and pressure only changes it, not melts it • Cracker, fluff, sprinkles, gummies: • Sedimentary rock full of layers of sediments!

  7. REVIEW • PAGE 105 12-19, 22 • PAGE 106 23-26

  8. The Layers of the Earth • I want you to learn: • Position • Composition • Density

  9. Inner Core • Solid • Most dense • Iron and nickel • (Location draw picture from board)

  10. The “why’s” • Why is it solid? • The intense pressure does not allow molecules to spread apart • Why is it in the middle of the earth? • It is so packed full of material, it sinks to the middle

  11. Outer Core • Liquid • Less dense than inner core • Iron and nickel

  12. The “Why’s” • Why is the outer core liquid? • It’s intensely hot!!!, not enough pressure to be solid • Closer to surface than inner core, so it’s less dense

  13. Mantle • Thickest layer • Plasticlike, not quite liquid, not quite solid • Almost “gooey” • Less dense than inner and outer core

  14. Crust • Outer skin of earth • Includes dry land and ocean floor • Continental crust: crust not covered with ocean water • Oceanic Crust: crust covered with ocean water • Least dense of all layers! So it seems to float….

  15. Lithosphere vs. Asthenosphere • Lithosphere: • Top sub layer • Includes both continental and oceanic crust • Top portion of mantle and the crust equals the lithosphere

  16. Asthenosphere • Sub layer most ooey-gooey portion of mantle

  17. 10/3 Today we will… • Review notes • Take short open note quiz on basic layers of earth • Review new (8th grade terms) vocab to describe the layers of earth • WORKSHEET ON CONVECTION

  18. Quiz #8 • 1. Which of the four layers is the thickest? • 2. Which of the four layers is at the center of the earth? • 3. Which of the four layers is the most dense? • 4. Which of the four layers is the least dense? • 5. What phase of matter is the inner core in?

  19. Oceanic vs. Continental crust • Crust covers the entire surface of earth • Some of the crust is under large bodies of water, some is not. • Can you determine which is which?

  20. Oceanic • Thinner than continental crust • Very dense • Under ocean water

  21. Continental crust • Thicker than oceanic layer • Land • Not as dense as oceanic…. • Why?

  22. What happens to hot air????Convection Cells/currents • Hot air ___________ • As it rises, it ___________ • Then that cool air __________ • It gets closer to surface of earth so it ___________up • Then it _____________ • This is called a _________________

  23. Worksheet!!! • LET’S RELATE THE CONCEPT OF HOT AIR RISES AND COOL AIR SINKS TO THAT OF MATERIAL IN THE MANTLE…. • APPLY WORKSHEET. USE PARTNERS.

  24. Quick animation • Mantle Convection | Flash simulation, Animation, Illustration, Picture, Diagram – eduMedia

  25. The Joke for 7th period • Two Geologists are walking across a granite outcrop one day. The first says to the second • - "Hey, this terrain is unmetamorphosed". Replies the second one, - • "No Schist". • GET IT, SCHIST IS METAMORPHIC ROCK AND GRANITE IS IGNEOUS.
