How are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
Process that forms new seafloor?
Seafloor Spreading
What process forms new seafloor?
Seafloor spreading at midoceanic ridges.
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
Studying the magnetic patterns of the rocks in the floor of the ocean helps scientists do what?
It helps them determine the frequency of shifts in the magnetic orientation of the Earth, and initially led to the confirmation of seafloor spreading at the mid-ocean ridges.
Paleomagnetic evidence was used to confirm which of the following hypotheses?
seafloor spreading
Who first related the symmetrical magnetic patterns in seafloor basalt to seafloor spreading at a mid ocean ridge?
Vine and Matthews
What causes the seafloor to spread?
rising molten magma
What kind of activity causes seafloor spreading?
Tectonic.
Which evidence causes most scientists to believe that seafloor spreading occurs at the mid-atlantic ridge?
Oceanic crust on both sides ofthe ridge shows matching patterns of reversed and normal magnetic polarity
First related the symmetrical magnetic patterns in seafloor basalts to seafloor spreading at a mid-ocean ridge?
Lawrence W. Morley, Frederick John Vine, and Drummond Hoyle Matthews were the first to tie magnetic stripe anomalies to seafloor spreading. The magnetic anomalies was the first evidence that supported the theory of seafloor spreading.
How do scientist date seafloor rocks?
Scientists date sea-floor rocks by looking at patterns in the rocks, including magnetic patterns, and by looking at the geomagnetic reversal time scale.
What primary force that causes the seafloor to spread and continents to drift?
Geothermal Drift.
How are magnetic patterns in sea floor rock evidence of seafloor spreading?

What causes regional wind patterns?
dhfhfkjngt
What causes the patterns of moonrise and phases?
The tide
How Does Seafloor Spreading Effect Continental Drift?
the primary force that causes the seaffloor to spread and contienents to drift
