Describe how magnetism is used to support the theory of seafloor spreading?

New material is added to the sea floor when sea floor spreading occurs. When the iron cools it is magnetized by the magnetic field of the earth.

How is magnesium used to support the theory of seafloor spreading?
No
How did Alfred Wegeners theory support the theory of seafloor spreading?
He supported the Seafloor Spreading Theory by first discovering the Continental Drift Theory.
How did seafloor drilling help scientists find the evidence to support the seafloor spreading hypothesis?
people here are stupid , really the answer is not hi
How did the new evidence support Hess's theory of seafloor spreading?
Umm Maybe by the way sea floor spreads apart along both sieds of a mid ocean ridge as new crust is added
How did research from the Glomar challenge help scientist support the theory of seaflooding spreading?
From Wikipedia: Starting from August 1968, the Glomar Challenger embarked on a year-long scientific expedition, the Deep Sea Drilling Program, criss-crossing the Mid-Atlantic Ridge between South America and Africa and drilling core samples at specific locations. When the age of the samples was determined by paleontological and isotopic dating studies, this provided conclusive evidence for the seafloor spreading hypothesis, and, consequently, for continental drift.

How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

How did seafloor drilling scientists find evidence to support the seafloor-spreading hypothesis?
dumb question. don't want to write it all

How do magnetic signatures support the idea that continents move?
Scientists indicated that the seafloor was spreading, so the poles "reverse"

Why did magnetic reversals on the seafloor support seafloor spreading?
Earth got its north and south Pole's have geographic and magnetic north and south poles which makes an angle of nearly 5.6degree. magnetic field created due to core of earth is reversed during each 100 million year period. ie.magnetic north becomes south and vice's. seafloor spreading is a continuous event so for each 100my spread seafloor we get opposite polarised magnetic substances. That is called magnetic reversal
How the age of the rocks on the ocean floor support the theory of the seafloor spreading?
the ages of the rocks become increasingly older in samples obtained farther from the ridge and the younger had just come out the ridge.
