70 Complete the ActivityUse this diagram in your ESRT to answer the following: What is the temperature for the interface between the following… inner core and outer core? 6250° C Outer core and stiffer mantle? 5000° C Stiffer Mantle and athenosphere? 2600° C Asthenosphere and lithosphere? 750° C
71 What is the depth of the interface between the stiffer mantle and the outer core? 2900 KM State the relationship between depth and pressure :As depth increase pressure increases State the relationship between depth and temperature: As depth increases temperature increases
