But it may cast some doubt that the earth's core and mantle (an obviously closed system) suddenly and inexplicably heated up and cracked the earth's crust, forming the tectonic plates.
I think not, but that isn't what this thread is about.

By 'heated up' I meant that the already hot center increased enough to expand and crack the crust. This after millions/billions of years of gradual cooling SO THAT THIS WOULD NOT HAPPEN. Talk to any potter about firing/glazing pottery.
So radioactive decay increased within the earth millions/billions(?) of years after the earth cooled to form a crust, dry land was formed, water was gathered into seas, biological life was formed, then shattered the crust into plates?
It all seemed so orderly up to that point.
I don't see why you assume it was ever uncracked. A hot center and a cooler outside connected by a liquid mantle would create convection currents that would keep the crust from remaining completely solid and immobile.

It seems to me that the logical progression of events would be the gradual cooling and consolidation of the crust, which would then form the substrate for everything else to form in an organised manner.
It's hard to draln the swamp when you're up to your butt in alligators.

What I means is that it seems unlikely that a destructive event would suddenly occur in the midst of such a 'natural' orderly procession of positive creative events.
The exception is of course is the deliberate intervention, by God , to cause that upheaval.
Romans 8:
20 For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,
21 Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
22 For we know that the whole creation groaneth and travaileth in pain together until now.
Verse 22 doesn't mean that the earth always groaned and travailed, but only since the 'casting down' of Lucifer. Prior to that it was perfect, just as Lucifer was perfect.

This thread is about entropy and thermodynamics. I just want to apply it to an actual physical event: the cracking of the earth's crust.
The problem is that thermo isn't the correct discipline to use. Thermo is about the ability of energy to do work. You've presupposed that the cracking of the crust happens for a particular reason, and are forcing yourself into finding the solution with the wrong tool. You need to use heat transfer, fluid dynamics and material science.
fragmentsofdreams is correct. With a molten mass the size of the earth, the outer layers would solidify while the underlying layers would stay molten. Heat transfer through the crust would set up convection currents in the molten mantle underneath, and the viscous drag against the bottom of the crust would set up stresses more than sufficient to cause cracking. Tidal effects would also cause magma flow, and in addition would set up cyclic fatigue loads in the crust.
You can see things like this on a small scale as well. Highly alloyed steel parts that have been hard quenched can spontaneously break because of stresses that are set up as the part crystallizes at different rates from the outside to the inside. I've seen test coupons at room temperature snap all by themselves just sitting on the table.
If you want to talk about this it would be better to go over to Physical Sciences and start another thread. It's really way off-topic here, this thread is about the very narrow issue of evolution and the Second Law.
