This confirmed the theory that Earth's magnetic field had flip-flopped ... transformed the field of geology. It confirmed sea-floor spreading as hypothesized by Hess, and thus "continental drift ...

Magnetic anomalies and the pattern of seismicity suggest that the present Chile Rise has been spreading at 2.7 cm/yr along a NNE axis. Older oceanic crust (25–55 m.y. BP) near the coast of Chile ...

Dalton and her co-authors studied magnetic records for 18 of the world’s largest spreading ridges, using seafloor ages and their areas to calculate how much ocean crust each ridge has produced ...

NASA has raised serious concerns about a large, mysterious anomaly that is spreading across the planet. This strange ...

Magnetometers, devices that measure Earth’s magnetic field ... the most powerful lines of evidence for the hypothesis of seafloor spreading, the idea that as Earth’s crust pulls apart at ...

the timing of their openings has been based on the appearance of these magnetic stripes," because scientists long believed that the stripes first appeared when seafloor spreading started ...

This confirmed the theory that Earth's magnetic field had flip-flopped ... transformed the field of geology. It confirmed sea-floor spreading as hypothesized by Hess, and thus "continental drift ...

A new global analysis of the last 19 million years of seafloor spreading rates found they have been slowing down. Geologists want to know why the seafloor is getting sluggish. A new global ...
