26. Sample Question: What is the depth of the outer and inner core boundary?
5100 km (remember units!!!)

27. 1.5 millions of atm.
Represents the Pressure at different depths

28. What is the temperatures at the lithosphere and asthenosphere boundary?
1000°C
Line represents the temperatures inside the earth

29. If the temperature is below the melting point, what phase is it in?
This dotted line shows the melting point of material in the Earth. What does melting point mean?
-From Solid to a Liquid
If the temperature is below the melting point, what phase is it in?
-Solid
Solid
Solid
Liquid
Solid
Which layers in the diagram have temperatures below the melting point? Which phases are they in?
Liquid phase where temps. are above the melting point.

30. Final Question:
