hacked off a chunk of sea ice--frozen ocean water--so that he, Rudolph,
and Hermey, the dentist elf, could drift away over the ocean before the Abominable

and drift around on the liquid beneath, much like Yukon C's ice block.
In this unit and the next two, we'll explore the equivalent for the Earth, with the hard-
frozen upper layer broken into drifting chunks, melt leaking up in cracks to feed
volcanoes (vaguely like the water in the crack that the 'Bumble fell into when trying to
catch the heroes), collisions causing earthquakes when blocks run together ("Land, Ho"),
and more. Hold onto your teeth, and let's get started for the land of misfit plate
