Study of the modern theory of continental drift—including plate tectonics, convection, seafloor spreading, paleomagnetism, and classical evidence—shows that there are more faults with the hypothesis of drift than reasonably can be accepted. It is suggested that seafloor spreading alone be regarded as valid, and that convection and paleomagnetism be considered doubtful.

The general theme of this publication is the assessment and reassessment of various data, observations, and ideas about the earth as they relate to the concept that has come to be known as plate tectonics. Much widely scattered material was brought together for this publication, and its 24 papers contain an abundance of worldwide references that are important in studying plate tectonics.
