Seafloor spreading definition a process in which new ocean floor is created as molten material from the earth s mantle rises in margins between plates or ridges and spreads out. Subduction and sea floor spreading are processes that could alter the size and form of the ocean.

The ridge sits atop a geologic feature known as the mid atlantic rise which is a progressive bulge that runs the length of the atlantic ocean with the ridge resting on the highest point of this linear bulge this bulge is thought to be caused by upward convective forces in the asthenosphere pushing. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

For a general explanation of mid oceanic ridges see mid oceanic ridge and seafloor spreading. What does the paper strip used in the model represent in real life. This idea played a pivotal role in the development of the theory of plate tectonics which revolutionized geologic thought during the last quarter of the 20th century. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century. Due to this continuous seafloor spreading occurs and makes atlantic ocean floor to be connected to other continental crust making the ocean gets wider over the time.

For instance the atlantic ocean is believed to be expanding because of its few trenches.
