How is a hard-boiled egg’s structure similar to the earth’s?

1. How is a hard-boiled egg’s structure similar to the earth’s?

2. Inside the Earth What are the characteristics of each layer of the Earth?

3. What are Earth’s layers and their characteristics?

10. Tomographists People who write or record about seismic discontinuities.

11. Draw and identify each layer based on the descriptions to the right. Continental Crust - the thick parts of the Earth's crust, not located under the ocean.Lithosphere - the crust plus the rigid, upper mantle.Lower Mantle (semi-rigid) - the deepest parts of the mantle, just above the core.Mohorovicic discontinuity - separates the crust and the upper mantle.Ocean - large bodies of water sitting atop oceanic crust.Oceanic Crust - thin parts of the Earth's crust located under the oceans.Upper Mantle (rigid) - the uppermost part of the mantle, part of the Lithosphere.Upper Mantle (flowing) = Asthenosphere- the lower part of the upper mantle that exhibits plastic (flowing) properties. It is located below the lithosphere (the crust and upper mantle).

12. What are the characteristics of the layers of the Earth?

13. #1 How are seismic discontinuities (disruptions in earthquake waves) uesful? Locating these distrubances enable (or help) scientists to map the inner regions of the Earth.

14. Oceanic and Continental Crust Which is thicker?

15. Outer layer Broken into pieces called plates Where plates meet it is called a “fault” Nearly all earthquakes and volcanoes occur along faults Part of lithosphere 2 types of crust Oceanic 0 – 6 miles thick, very dense made of basalt or volcanic rock thinnest and newest crust Continental 0 – 31 miles thick less dense made of crystalline rocks such as granite thickest crust The Crust

16. The crust is broken into pieces called what?

17. Mohorovicic Discontinuity • Transition region • Has qualities of both the crust and the mantle

18. Earth’s ________ is divided into sections. crust

19. The place where plates meet is called a … Fault

20. Brainpop! Earth’s Layers

21. Part of lithosphere On top of asthenosphere 6 – 250 miles thick can move and reshape through convection contains magma and Olivine partially molten Lower mantle Silicon, magnesium, and oxygen solid The Upper Mantle

22. Thinnest layer of crust oceanic crust

23. Middle layer Very thick layer Hot, dense molten rock Movement of matter releases energy generated in the Earth’s interior causing earthquakes on the surface of the Earth The Asthenosphere

24. Crust

25. Molten rocks in motion Mantle

26. Beneath the crust Mantle Ok answer Moho Great answer

27. Inner Core

28. #2 Due to convection, which layer moves as the asthenosphere moves? the lithosphere moves causing earthquakes

29. Made of silicon, magnesium, and oxygen Mostly solid The Lower Mantle

30. The Core • 1/3 of the earth’s mass • Very hot! • 2 types of core: • Outer core • 125 – 188 miles thick • mostly liquid • Conducts electricity • Inner core • Completely SOLID • mostly iron and nickel • under lots of pressure • Responsible for Earth’s magnetic field • Causes a jolt in Earth’s rotation nearly every day

31. Solid iron Inner Core

32. Mantle

33. Under the mantle Outer Core

34. Plates ride on top Mantle

35. Melted iron Outer Core

36. Center of Earth Inner Core

37. Outermost layer Crust

38. These sections are known as … Plates

39. Solid rock, often with caves, that has been shaped by weathering, erosion, and plate movement Crust

40. Outer Core

41. Most volcanoes and earthquakes are located at the … Faults

43. Summary: Earth’s Layers I already knew… I learned… I am confused about…

44. ____________ The two types of crust and their characteristics. ____________ Explain what the Mohorovicic Discontinuity is. ____________ Tell someone about the difference between the lithosphere and the asthenosphere. ___________ Explain what “molten” rock is. Use your spiral to tell your family about…Have your parent/guardian sign the line after you have discussed it.
