You've pretty much answered your own question,The least path of resistance, compression and as you say environmental stress all play a role and I'm sure many more factors we probably haven't dawned on just yet, but adaption to this is key for all life and what we call inanimate objects.It maybe a moment of brief sustained stability but in the end it will transition to what we call failure, ahh! but for a moment we have stability a prime of life and then a slow demise.One need only to look at one's own life!
This is all subjective of course but can still be measured!
