seafloor spreading

These locations are usually under the ocean floor at seafloor spreading centers.

The second stage involved seafloor spreading, which began in Jurassic time and continues today.

At this point, seafloor spreading becomes the driving force.

Finally, volcanos sometimes form in the middle of the ocean, above seafloor spreading centers.

Part of the model was the origin of the seafloor spreading concept.

Sea levels began to rise during the Jurassic, which was probably caused by an increase in seafloor spreading.

This theory builds on older ideas of continental drift and seafloor spreading.

Since then, it has been shown that the motion of the continents is linked to seafloor spreading.

These stripes provide quantitative information on seafloor spreading, a part of plate tectonics.

The geoscientific community accepted the theory after the concepts of seafloor spreading were developed in the late 1950s and early 1960s.

Seafloor spreading happens at the bottom of an ocean as tectonic plates move apart.

The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope.

This is followed by passive margin environments, while seafloor spreading continues and the oceans grow.

Seafloor spreading is closely related to the theory of Plate Tectonics.

Seafloor spreading helps explain continental drift in the theory of plate tectonics.

This geophysical evidence also spurred the hypotheses of seafloor spreading and paleomagnetism.

Accretion occurs as mantle is added to the growing edges of a plate, usually associated with seafloor spreading.

Calcite seas occurred at times of rapid seafloor spreading and global greenhouse climate conditions.

As the seafloor spreading axis moves along the margin, thermal uplift produces a ridge.

And she wondered in turn whether that rift might be evidence of what scientists now call seafloor spreading, popularly known as continental drift.

The theory of seafloor spreading was developed in 1960 by Harry Hammond Hess.

This area is considered a present day example of continental rifting leading to seafloor spreading and producing an oceanic basin.

Two of these evolve to the point of seafloor spreading, while the third ultimately fails, becoming an aulacogen.

Some scientists interpreted these as requiring plate tectonic processes, such as seafloor spreading.

Continued seafloor spreading leads to the formation of oceanic crust of normal thickness.
