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.
Rock on the ocean floor provided the final proof of sea floor spreading with a record of?
theory that explains how continents reached their current place
Which spreads faster on the floor water or kerosene?
Water spreads faster. Kerosene is an oild with higher viscosity.
What is magnetic striping evidence of?
Magnetic reversals and sea floor spreading.
What is used as evidence for sea-floor spreading-?
The rocks on either side of a mid-ocean ridge record the direction of the Earth's magnetic field at the time they were formed, and form a pattern of 'magnetic stripes' on either side of the ridge which are symmetrical. It is also now possible to measure ocean widths with sufficient accuracy to show yearly changes.
Why do magnetic stripes appear on the sea?

How a prediction and then evidence of magnetism in rocks on the ocean floor proved that the seafloor spreads?
The Earth's magnetic reversals have been recorded in newly forming oceanic seafloor basalt by the orientation of magnetic minerals which become frozen in place as the magma hardens. When the next reversal occurs, it as well becomes part of the ocean floor magnetic record.
The magnetic record in the rock on the ocean floor depends on when the rock was?
i dont know
What happens to the old ocean floor as the sea floor spreads?
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
Identify how magnetic symmetry can be used as evidence of sea floor spreading?
As the sea floor spreads the magnetic orientation in the rocks as they cooled is preserved. As the earth's magnetic field changes then a distinct pattern is imprinted in the rocks. If sea floor spreading is true then this unique pattern should be the same on both sides from the spreading point. Measurements of sea bottom rocks verify this symmetry is true. :)
Is hit the floor the name of a record?
Yes, hit the floor is the name of a record. The band/singer that has created that record is called breakestra. The record costs about sixteen dollars.
Rock on the ocean floor provided the final proof of sea floor spreading with a record of?
theory that explains how continents reached their current place
What cause a new sea floor to be created and how is it created?
Sea floor spreading causes this. As the floor spreads apart new magma is being pushed up through the ridge from the mantle through convection currents. It's like a recycling system.
Where is ocean floor created?
The ocean floor is made of relatively young basaltic rock which is pushed up as magma at the mid-oceanic ridges, the place where the sea floor spreads apart.
Which spreads faster on the floor water or kerosene?
Water spreads faster. Kerosene is an oild with higher viscosity.
How magnetic reversals provide evidence for sea floor spreading?
Because of the stripes at the sea floor which are magnetic minerals
