RSGEC Dynamic Earth

In this section, we offer some useful concepts about Earth’s structure, plate drift and plate classification in terms of Earth’s age. It contains the spreading speed of oceanic plates and their asymmetry in the state of motion. The drift of plates certainly affects Earth’s magnetic field and gravitational field. Data of the residual oceanic basement depth are useful in investigating tectonics of oceanic crust, volcanoes and oceanic engineering development.
