All About Earth (Core to Crust; Includes Facts; Q/A & much more)
- 2. What are the four basic areas of Earth Science?
- 5. Has anyone been able to reach the core of the earth? How were scientists able to study the earth’s interior?
- 8. Q1.The core of the Earth is made up almost completely of which element? A. Iron B. Granite C. Sulfur D. Calcium earthscience: LAYERS OF THE EARTH
- 9. Q2.Which layer of the earth is the thickest? A. Core B. Crust C. Mantle D. All of them have the same thickness earthscience: LAYERS OF THE EARTH
- 10. Q3.Which layer of the Earth is liquid? A. Crust B. Outer Core C. Inner Core D. Lithosphere earthscience: LAYERS OF THE EARTH
- 11. Fact toknow! • Earthquakes occur when heat travels through the mantle and causes tectonic plates to shift. earthscience: LAYERS OF THE EARTH
- 12. • 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. earthscience: LAYERS OF THE EARTH
- 13. How does the interior of the Earth look like?
- 19. ? ? Crust
- 20. oceanic ? Crust
- 23. oceanic continental Crust Made of basaltic rocks Thinner compared to continental crust Heavier than continental crust
- 24. oceanic continental Crust Made of granitic rocks Thicker compared to oceanic crust Lighter than oceanic crust
- 26. The crust of the Earth is broken into many pieces called …
- 27. plates plates plates The crust of the Earth is broken into many pieces called ….
- 29. What’s the behavior of the plates? plates plates plates
- 36. The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere..
- 38. The layer below the rigid is a zone of asphalt-like consistency called the
- 39. The layer below the rigid lithosphere is a zone of asphalt-like consistency called the Asthenosphere.
- 41. The asthenosphere is the semi-rigid part of the middle mantle that flows.
- 43. The between the crust and the mantle is called the...
- 45. The between the crust and the mantle is called the .
- 46. Is the temperature all over the mantle the same or constant?
- 48. When the convection currents flow in the asthenosphere they also move the crust.
- 55. ? ? CORE
- 56. INNER OUTER CORE
- 61. The boundary between the outer core and the mantle is called Gutenberg Discontinuity.
- 63. INNER CORE OUTER CORE Made of molten metals. Consists mostly of nickel and iron.
- 66. What is the inner core made of?
- 67. INNER CORE OUTER CORE Made of compacted metals. Consists mostly of iron.
- 68. Q. Why is the inner core solid despite its extremely high temperature?
- 69. Answer. • Extremely high pressure as well. The melting point of iron increases a lot under very very high pressure. • And therefore it is in solid state whereas outer core is in liquid state 69
