Describe how the seafloor move
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.

By the late 1960s, several American investigators, among them Jack E. Oliver and Bryan L. Isacks, had integrated this notion of seafloor spreading with that of drifting continents and formulated the basis of plate tectonic theory.

WebSeafloor spreading is the mechanism for Wegener’s drifting continents. Convection currents within the mantle take the continents on a conveyor-belt ride of oceanic crust that over millions of years takes them around the planet’s surface.
