Further to my note on advection I found my notes on heat transfer and “it says” Quote “advection is rather like the upward part of convection; movement of a whole region (e.g. In isostatic rebound)takes heat up with it.” Unquote Open University ---“Understanding the Continents”
Of course appropriate to earth science physics more so then the original discussion put forward.

If I remember Physics 101 (and numerous fire classes); heat is transferred by (1) direct contact (touching a flame); (2) convection (heating a gas; a house furnace moves warmed air into the room); (3) conduction (movement through a solid; brick ovens) and (4) radiation (movement through space; solar heating the planets).
Time for a snooze, I’m getting too wordy.

Lin, to the rescue again. :-D Good job!
I’m too pooped to read that tonight. Was I close in my guess?

Here is an excellent explanation for decompression/partial melting:
