During the past decade, research by oceanographic geophysicists which has led to the wide acceptance that continents drift about the face of the earth and to the concept of sea-floor spreading has culminated in an all-embracing theory known as 'plate tectonics.' This theory draws sea-floor spreading, continental drift, crustal structures, and world patterns of seismic and volcanic activity together as aspects of one coherent picture.
