Dec 16, 2019 · To understand the concept of Seafloor Spreading, we must first understand some basic concepts that form the cornerstones for the concept of Seafloor Spreading. These cornerstones are Convectional Current Theory and Paleomagnetism. Convection Current Theory Convection Current Theory is the soul of Seafloor Spreading Theory. Arthur Holmes in 1930s discussed the possibility of …

Jun 11, 2010 · Since we know that geomagnetic reversals occur (south magnetic pole becoming north magnetic pole and the other way around), then if we can see the "striping" of paleomagnetism on the seafloor, then we can see that as the north-south direction keeps flopping, the floor must be moving away from the spreading center in order to record these flops.

In this lesson, we will look at the study of paleomagnetism, as well as research on hot spots, and show how they provide strong evidence for plate tectonics, and therefore support for Wegener's ...

Apparent polar wander paths provided the first clear geophysical evidence for continental drift, while marine magnetic anomalies did the same for seafloor spreading. Paleomagnetism continues to extend the history of plate tectonics back in time and are applied to …

Lecture #26: Rock Magnetism and Sea-floor Spreading. The Earth's magnetic field - invisible lines of magnetic force surrounding the earth deflect magnetized objects, such as compass needles, that are free to move. The Earth's magnetic field has north and south poles. Geophysical observations suggest that the Earth's magnetic field is generated within the liquid of the Earth's metallic outer core.

How does paleomagnetism support the plate tectonics theory? - Once every 200,000 years, the Earth's magnetic field REVERSES polarity. - As constructive plates add new rock to the surface, this could and magnetic minerals within the rocks aligns itself with the direction of the earth's magnetic field.
