WebSeafloor Topography Continents fit together along the edges of their continental shelves. Mid-ocean ridges and deep-sea trenches develop at the boundaries of the moving plates. Volcanic islands and seamounts develop where a plate moves over a stationary hotspot. The new earthquake data revealed three startling observations. WebA synchronized coordination of all the tube feet allows the echinoderm to move—almost as if it were gliding. Sea stars creep along the seafloor using hundreds of little tube feet. These tube feet function through a water vascular system that extends and retracts the feet using hydraulic forces. (© Saeed Rashid, Flickr)
