The mid-ocean ridges where tectonic plates meet in the Atlantic and the Pacific Oceans are seething with volcanic activity. The most active areas are deep under water, several thousand metres down. Ocean water penetrates several kilometres down towards the centre of the Earth where the crust is fractured. Geologists call this hydrothermal activity.
