The feedback loop cooling principle is the same = lots of snow cover, cloud and frozen ocean reflects sunlight and makes the place cooler which makes more snow cover, more cooling and so on. But to get to the cause these days, you need to think of depletion of the atmosphere by ecosphere stripping of it into the oceanic crust and subduction of it, and sedimentary limestone deposits with some hydrocarbons held. Err... you have a slight timescale problem there don't you? Any climate change with a root cause in plate tectonics is many orders of magnitude slower than changes from atmospheric global warming or cooling. Plate tectonics has no doubt been a factor in not only the earths temperature, but also the diversity of both plant and animal life we see today as well as for that matter the current location of the moon. But the effects are over very long timescales.
