It is also said that he thought that the rectangular chambers looked like the cells in some monasteries. Physically cells always have a boundary membrane, a little like a polythene bag encloses contents within it. Inside the space limited by the membrane there is an remarkable chemical processing unit.
Iceland is a place where, because of large amounts of lava extrusion, the ocean floor is, in effect, above sea level, making it easy to study ocean floor spreading. You can affix strain gauges on many parts of the spreading ridge. 6 people found this useful.
Subduction is the process that destroys oceanic crust, and sea-floor spreading is the process that creates oceanic crust. Sea-floor spreading is driven by crust formation along the mid-ocean ridges, meandering undersea mountain ranges that span Earth like the seams of a baseball.eafloor spreading Theory that explains how continental drift occurs. It proposes that the ocean floor is moved laterally as new basalt rock is injected along mid-ocean ridges, and so the ocean floor becomes older with increasing distance from the ridge.
