Sea Floor Spreading Occurs When

Seafloor spreading is a geological process which involves the splitting of tectonic plates and their movement away from each other.

Sea floor spreading occurs when.

Seafloor spreading occurs at which type s of plate boundary. A canyon on the ocean floor where the crust bends downward. As tectonic plates slowly move away from each other heat from the mantle s convection currents makes the crust more plastic and less dense. The process by which the ocean floor sinks into the mantle.

Eventually the crust cracks. Molten material erups the central valley of mid ocean ridges. A chain of underwater mountains along which seafloor spreading occurs. 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.

A deep ocean trench is an underwater. Seafloor spreading is a geologic process where there is a gradual addition of new oceanic crust in the ocean floor through a volcanic activity while moving the older rocks away from the mid oceanic ridge. Down the middle of underwater mountain ranges is a device that scientist use to map the ocean floor. Where does sea floor spreading occur.

Seafloor spreading occurs at spreading centers distributed along the crests of mid ocean ridges. The mid ocean ridge is where the seafloor spreading occurs in which tectonic plates large slabs of earth s lithosphere split apart from each other. The process that continually adds new material to the ocean floor. Seafloor spreading occurs at divergent plate boundaries.

The less dense material rises often forming a mountain or elevated area of the seafloor.
