The floors of the oceans, under the sea-bed silt, are primarily basalt, forming a crazy-paving of "Plates" surrounding the granite Continental Plates. Together they form the Earth's Crust, and the latter plates are constantly shuffling around the globe, with the ocean plates being formed and destroyed to accommodate this Continental Drift. The suite of processes is called Plate Tectonics, and although overall of great benefit to life on Earth, the local effects are often extremely destructive earthquakes and volcanic eruptions.
