Hi Sidmouth, nice to see you here.

Why won't present rising CO2 levels be naturally removed the same as in past natural events?

Thank you. Fascinating. Had to leave early, unfortunately.

So will the upwelling breakthrough if the assembled supercontinent be repeated in similar zones of weakness so the continents remain more or less the same?
Carolyn
01:02:25
does the increase in upwelling link to an increase in heat at the surface from the core/mantle boundary?
David Ifold
01:04:18
Thank you very much but I have another Zoom to go to!
NichOFarr

What effect does earths rotation have on supercontinent creation/breakup?
iPad (5)Linda
01:05:04
Could girdle conditions be sufficient to break existing continental slabs?
Mark Vanstone
01:05:25
Does seismic tomography give evidence of trapped heat beneath the current continental masses?
Mark Vanstone
01:06:21
How does the slab graveyard prompt plume formation, is it insulation, or chemistry of the slab?
Mark Vanstone
01:08:18
What current evidence is there for the break up of Eurasia and the formation of a new ocean in the proposed future supercontinent models showed on one of your slides?
NichOFarr
01:12:05
Will we have new mineral deposits created by these super-continent movements, and how much prediction have we at the current time?
Simon.Clifford
01:18:45
Is there evidence of previous asteroid/meteorite collisions with Earth affecting the formation (or destruction) of supercontinents ?
