Hair-brained idea of mine.

This seems to fit with an idea I've had about what happened to water on Mars, other than what ended up on the poles. Perhaps some of the magma under the crust cooled enough to solidify and therefore decrease in volume. Perhaps the crust was rigid enough to resist sinking at the same rate the magma underneath cooled, and perhaps cracks formed in the crust. If this happened under the ocean, then perhaps water would go through the cracks in the crust and fill the growing gap between the mantle and crust. Maybe the cooling effect of the water would increase the rate that the mantle cooled creating an even greater gap between the crust and mantle to be filled with more water. Any water boiled off in the process would cool and eventually rain back down and likely flow into one of the cracks in the crust. Maybe this process would screw with the weight distribution of Mars enough to shift it's position.

I hope this makes sense. I know it's not related to politics or atheism, but I felt like I needed to post this hair-brained idea.
