Today as I was cooking up a batch of tapioca pudding a thought occurred to me. Given the teaching habits of one of my professors, I now have a propensity for finding geologic analogies in food. Which can sometimes be a messy habit. Today that took shape in the form of pudding. As I sat and stirred over medium-low heat as not to let the tapioca stick to the bottom of the pot, I would watch little tapiocas (?) rise in some places travel along and sink near the edges. Then it dawned on me. I was watching at a food inspired geologic analogy for the asthenosphere!

As the heat from the stove (heat from radioactive decay) warms the pudding (partially melted rock of the asthenosphere) it becomes less dense and rises. Once it reaches the surface (or the under belly of the lithosphere) it flows away from the spreading center. Being pushed by and pushing other little tapiocas in their path. Once they are far enough away they either cooled enough or collided with the scummy build-up along the edge of the pot (the continental crust).  My little tap’s would then dive back into the depths of the “asthenosphere” to be heated up again, and repeat the entire process.

I also consider that if I let enough of the scummy build-up propagate out, I could have an analogy for plate tectonics as well.

Needless to say, as I sat and watched this (and took pictures and video) I let the tapioca burn and stick to the bottom of the pot.

What do you think? Is this an accurate analogy or do I need some fine tuning?
