Why are the temperatures of the rock inside the Earth at 100 km similar in a normal situation and at a convergent plate boundary?

1) Using Figure A, what is the temperature of the rock inside the Earth at a depth of 100 km a) in a normal situation b) at a divergent plate boundary (mid-ocean ridge) c) at a convergent plate boundary (subduction zone) 2) Why do the temperatures of the rock inside the Earth at 100 km […]
