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
73 When rocks melt, bonds broken. Crystalline solid no longer exists. MELTING ROCKS AND CRYSTALLIZING MAGMARock magma magma rockWhen rocks melt, bonds broken.Crystalline solid no longer exists.
74 Hot liquid contains still solid fragments MELTING ROCKS AND CRYSTALLIZING MAGMARock magma magma rockHot liquid contains still solid fragmentsMinerals melt at different temperaturesMelting causes changes in magma composition
