When the molten magma reaches the oceanic crust it cools and pushes away the existing rocks from the ridge equally in both directions.

Cause and effect of sea floor spreading.

When oceanic plates diverge tensional stress causes fractures to occur in the lithosphere. The new rock is dense but not as dense as the old rock that moves away from the ridge. As tectonic plates slowly move away from each other heat from the mantle s convection currents makes the crust more plastic and less dense. This is sea floor.

Seafloor spreading creates new oceanic crust at a mid ocean ridge. Sea floor spreading is caused by convection currents in the mantle to cause a divergent boundary underwater. One of the primarily effects of seafloor spreading is the creation of new seafloor or oceanic crust. Sea floor spreading continued 11.

The ocean is changed in size and shape. Complete the cause events and effect graphic organizer to show the relationships among the processes of convection currents subduction and sea floor spreading. What process in earth s interior causes subduction and sea floor. With the creation of new seafloor it pushes the older seafloor out of the way.

Seafloor spreading occurs at divergent plate boundaries. What effect do those two events have on earth s surface. Eventually the crust cracks. In sea floor spreading where does new crust come from.

The less dense material rises often forming a mountain or elevated area of the seafloor. The process of continental drift now better known as plate tectonics is driven by creation of new ocean crust at sea floor spreading sites like the mid atlantic ridge and east pacific rise and compensatory mechanisms of lithospheric subduction often at continental margins. Seafloor spreading adds material to oceanic plates causing the oceanic plate to come into contact with other plates but not necessarily causing those affected plates to drift. What process in earth s interior causes subduction and sea floor spreading.

The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones rather than magma pressure although there is typically significant magma activity at spreading ridges. A younger oceanic crust is then formed causing the spread of the ocean floor. When the divergent boundary spreads it caues a mid ocean ridge. Is the pacific ocean shrinking or growing.
