Wise words from my astronomy teacher, P-Dog:
Continental drift (or plate tectonics) reminds me of…gravy. Specifically the skin that forms on gravy, the day after Thanksgiving, where you pull it out of the refrigerator, and slowly warm it back up on a stove, because microwaving your gravy is just wrong. As the gravy gradually warms up, convection currents form, circulating below the gravy skin, pulling sections apart at certain places where warm gravy rises, or drawing together sections at certain places where cool gravy sinks. The next day after Thanksgiving, try this out for yourself, and imagine that we are just living on floating sections of gravy skin.
