When new basalt forms along ocean ridges it becomes magnetized how?
While it is molten it is above the Curie temperature and is not magnetic, as it cools below this temperature the ambient magnetic field becomes "frozen" into the basalt.
Why do magnetic stripes appear on the sea?
The seafloor spreads apart, creating new rocks that record magnetic orientation. Small grains of magnetite on the volcanic basalt (ocean floor) have magnetic properties.
Why do magnetic stripes appear on the seefloor?
The seafloor spreads apart, creating new rocks that record magnetic orientation. Small grains of magnetite on the volcanic basalt (ocean floor) have magnetic properties.
What are two pieces of evidence for sea-floor spreading?

When new basalt form along mid-ocean ridges it becomes magnetized?
accorsing to the earths magnetic field
How would the history of reversals show itself on the ocean floor?

Who first related the symmetrical magnetic patterns in seafloor basalt to seafloor spreading at a mid ocean ridge?
Vine and Matthews
When new basalt forms along mid oceans ridges it becomes magnetized?
accorsing to the earths magnetic field
What type of rock is black all the way through non magnetic and non flamable?
Basalt is on of the many rocks that is black, obsidian (a volcanic glass) is another.
