What are three kinds of evidence scientists have discovered to support the idea of the ocean floor spreading?
molten material, magnetic stripes, and the ages of the rock.
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.
What did the magnetic strips prove in seafloor spreading?
They proved that the seafloor was spreading.
What is magnetic striping evidence of?
Magnetic reversals and sea floor spreading.
What was the theory that was shown to be correct by age evidence and magnetic clues?
Magnetic Reversal
Who first related the symmetrical magnetic patterns in seafloor basalt to seafloor spreading at a mid ocean ridge?
Vine and Matthews
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.
What is the primary evidence that forms the basis of seafloor spreading?
The magnetic properties of rocks along the mid-oceanic ridges change alignment in a symmetrical manner.
How do magnetic signatures support the idea that continents move?
Scientists indicated that the seafloor was spreading, so the poles "reverse"
How do earth's magnetic signatures support the idea that continents move?
Scientists indicated that the seafloor was spreading, so the poles "reverse"

What did scientist discovere when they analyzed the magnetic bands on the ocean floor?
Scientists found Alternating bands of magnetism.
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.
What is shown by magnetic minerals spreading from a mid ocean ridge?
That magnetic minerals spreading from a mid-ocean ridge
