The largest island in the world.
At least, according to wikipedia; but as Pluto The Small, a planet by definition for decades, became a non-planet, by definition, for some more decades, so, may, the status of Greenland The Large, be subject to the whims of definition.
“Whims” may prove to be unfair, to the extent that the word implies fad or fashion or fleetness of thought. Explorers of old drove their wind dependent vessels as best they could across oceans of deep, tectonic-fault concealing, waters. There may have been things they missed.
Greenland resides upon, what geologists call, the North American Plate. Greenlanders, perhaps feeling more closely akin to Europe, nevertheless find themselves locked into the movements of the plate of North America, whether pushing towards, or pulling from, the, even greater, plate of Eurasia.
Organized by size, there are 7 major tectonic plates and 13 or so minor tectonic plates. The word “tectonic” is derived from the Latin “tectonicus” and the similar, earlier, Greek “tectonikos”, words utilized to connote a carpenter, a builder or other master of a craft. So these great “plates” are the ‘cobbled together’ structure underlying the land upon which we walk- our world, this “pale blue dot”, upon which we all stand, and upon which we all depend. Greenland’s connection with Canada and the United States is thus creational, according to the geologists, even though its culture may be much more European.
