Earth science:  Just add more water

Rob Evans1

Top

Data from a different technique for probing events within the Earth, interpreted in terms of a new hypothesis about the effects of water at depth, raise tantalizing questions about recycling of a tectonic plate.

In places such as the Pacific Rim, the sea floor collides with and is pushed below the land masses that border the ocean. This process of subduction, and its consequences in the form of earthquakes and volcanism, are the result of plate tectonics, in which the formation of sea floor at mid-ocean ridges is accommodated by the recycling of tectonic plates in the Earth's interior.
