Unformatted text preview: must be happening nearby, at plate boundaries, and maybe at the bottom surface of the plate we are riding on. But even that knowledge is mostly conjecture. OCE 661 OCE 661 OCE 661 OCE 661 OCE 661 OCE 661 OCE 661 So, rather than gloss over the issues, let’s use this as a So, starting point for discussion of the outstanding issues. This discussion will be woven into the course throughout, but we’ll get started with an overview of what works and what doesn’t work so well with mantle convection, plate driving forces, and plate tectonics. To begin, we have to let go of the idea that plate tectonics and mantle convection form a well defined “Unified Theory”. Much like the elusive Unified Field Theory that frustrates physicists today, the commonly taught version of plate tectonics and mantle convection isn’t what it appears. Lets start with what we think we know about basic convection…. convection…. OCE 661 Simple convection of a fluid heated at is base is well described Simple by Rayleighs hydrodynamic stabili...
