Word History

Etymology

cryo- + -sphere, after Polish kryosfera

Note: The Polish term was introduced by the geophysicist and meteorologist Antoni Bolesław Dobrowolski (1872-1954) in Historja naturalna lodu (Warsaw, 1923), p. ii: "… lód tworzy naprawdę powłokę globu, składem nadzwyczaj jednostajną, wyglądem nadzwyczaj urozmaiconą. Ta powłoka lodowa—kryosfera—wchodzi w stosunki ścisle, określone i osobliwe z hidrosferą, z litosferą, z atmosferą." ("… the ice comprises in truth a global envelope, extremely uniform in composition, extremely diverse in appearance. This envelope of ice—the cryosphere—enters into a close, definite and peculiar relationship with the hydrosphere, lithosphere and atmosphere.")

First Known Use
