The continents and their attributes - mountains, deep rifts and unknown underground spaces - are not set in splendour for all eternity. Far from being unchanging landmarks, they are born, expand and succumb to the assault of time, like living beings. The continents join together and separate, victims of collision and subduction - movements we perceive through earthquakes and tsunamis. The history of the continents is part of the “tectonic waltz” of land and sea - a concept as important to the history of the Earth as Darwin’s theory is to the evolution of Man. The Waltz of the Continents recounts this odyssey.
