  6. EARTH’s INTERIOR

  7. Task: Answer the following • questions. earthscience: LAYERS OF THE EARTH

  8. earthscience: LAYERS OF THE EARTH • Which is not a layer of the Earth? • Crust • Mantle • Outer Core • Inner Crust

  9. earthscience: LAYERS OF THE EARTH Starting with the outermost layer, what is the order of the Earth’s layers? A. Core - Mantle – Crust – Inner Crust B. Crust - Mantle - Outer Core - Inner Core C. Outer Mantle - Inner Crust – Inner Core D. Outer Crust - Inner Core – Outer Mantle

  10. earthscience: LAYERS OF THE EARTH The core of the Earth is made up almost completely of which element? A. Iron B. Granite C. Sulfur D. Calcium

  11. earthscience: LAYERS OF THE EARTH Which layer of the earth is the thickest? A. Core B. Crust C. Mantle D. All of them have the same thickness

  12. earthscience: LAYERS OF THE EARTH Which layer of the Earth is liquid? A. Crust B. Outer Core C. Inner Core D. Mantle

  13. earthscience: LAYERS OF THE EARTH • TRUE OR FALSE? • The center of the Earth is made of molten rock. • Most of the Earth’s heat is stored in the mantle. • The outer core is liquid. F T T

  14. earthscience: LAYERS OF THE EARTH • TRUE OR FALSE? • Earthquakes occur when heat travels through the mantle and causes tectonic plates to shift. • The thinnest parts of the Earth’s crust are its continents. T F

  15. earthscience: LAYERS OF THE EARTH • TRUE OR FALSE? • Extreme pressure causes the inner core of the Earth to remain solid. • The crust of the Earth is much cooler than its other layers. • The Earth’s mantle is flexible and shifts under heavy loads. T T T

  16. earthscience: LAYERS OF THE EARTH • TRUE OR FALSE? • The core is where geologists look for oil, gas, and other resources. • The crust is separated into two parts: upper and lower crust. F F

  17. How does the interior of the Earth look like?

  18. It has different layers.

  28. The crust of the Earth is broken into many pieces called ….

  29. Lithospheric Plates

  30. What’s the behavior of the plates?

  31. They are in constant motion.

  32. What makes them move?

  33. Continental crust Crust Outer core Inner core mantle Oceanic crust

  34. 2nd Layer: Mantle

  35. Give a description of the mantle.

  36. Terms Asthenosphere? Lithosphere? • Mohorovicicdiscontinuity?

  37. The crustand the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere..

  38. The layer below the rigid lithosphere is a zone of asphalt-like consistency called …

  39. The layer below the rigid lithosphere is a zone of asphalt-like consistency called theAsthenosphere.

  40. The asthenosphere is the semi-rigid part of the middle mantle that flows.
