Seafloor Spreading Occurs At The Divergent Plate Boundaries

This occurs above rising convection currents.

Seafloor spreading occurs at the divergent plate boundaries.

Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre important evidence in favour of this process. The rising current pushes up on the bottom of the lithosphere lifting it and flowing laterally beneath it. 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 lateral flow causes the plate material above to be dragged along in the direction of flow.

Spreading center volcanism spreading center volcanism occurs at rift zones where two plates are moving apart from each other. Seafloor spreading is most likely to occur at. Most commonly this is the case at mid oceanic ridges where two oceanic plates move apart. As upwelling of magma continues the plates continue to diverge a process known as seafloor spreading.

A divergent boundary at two continental plates can result in a rift valley list the locations in the correct sequence with the initial seafloor spreading stage first followed by more advanced stages in the seafloor spreading process. Hawaii is an example of. Plate tectonics plate tectonics seafloor spreading. Seafloor spreading occurs at boundaries.

Divergent plate boundaries are locations where plates are moving away from one another. Divergent boundaries within continents initially produce rifts which eventually become rift valleys most active divergent plate boundaries occur between oceanic. Illustration of the main types of plate boundaries 55 k divergent boundaries. In plate tectonics a divergent boundary or divergent plate boundary also known as a constructive boundary or an extensional boundary is a linear feature that exists between two tectonic plates that are moving away from each other.

Seafloor spreading occurs at divergent plate boundaries. Plate boundary zones broad belts in which boundaries are not well defined and the effects of plate interaction are unclear. The less dense material rises often forming a mountain or elevated area of the seafloor. So sea floor spreading occurs at a divergent boundary.

These age data also allow the rate of seafloor spreading to be. Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. The developing boundary between two spreading continental plates is known as a continental rift. In other words diverging.

Within either continental or oceanic plates.
