Schematic diagram showing the mechanism of seafloor spreading.

Sea floor spreading diagram.

Start studying section 4. This diagram provides evidence of seafloor spreading by showing the ages of ocean floor in the atlantic and eastern pacific oceans. Seafloor spreading is a process that occurs at mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. The red colors are the youngest parts of the seafloor where fresh new crust is formed as lava seeps up from the deep interior of the earth at spreading ridges.

Lithosphere the crust plus the rigid upper mantle. Figure showing sea floor spreading the intense heat generated by radioactive substances in the mantle beneath the lithosphere seeks a path to escape and forms convection currents. The mid ocean ridge was mapped by sonar b. Sea floor spreading in the early 1960s princeton geologist harry hess proposed the hypothesis of sea floor spreading in which basaltic magma from the mantle rises to create new ocean floor at mid ocean ridges.

The rising convectional currents continuously bang thick but strong oceanic sima crust and the hammering effect leads to the development of cracks joints fractures and disintegration of oceanic ridges. Magma molten rock withing the earth s mantle. The size of an ocean is determined by how fast is created at a mid ocean ridge. Lower mantle semi rigid the deepest parts of the mantle just above the core.

Ocean floor diagram worksheet. History of study earlier theories by alfred wegener and alexander du toit of continental drift postulated that continents in motion plowed through the fixed and immovable seafloor. Select the letter that is true about the mid ocean ridge. Read the definitions below then label the seafloor spreading plate divergence diagram.
