p. 313. Ocean floorlocked

  • Dorrik Stow


‘Ocean floor’ examines the morphology, composition, sediment cover, and cycles of change of the ocean floor. The jigsaw puzzle of tectonic plates and their movement about the Earth determines the nature and shape of the seafloor, which is as varied as it is variable. But all these features change with time and in cyclic patterns of change with varying timescales. The plate tectonic cycle is the longest, and is closely linked with the cycle of the rocks, from continent to ocean to the Earth’s interior and back. The flux of sedimentary materials into and through the oceans is complex, at times sudden and catastrophic, otherwise slow and continuous.
