What properties of iron bearing minerals on the seafloor support the theory of seafloor spreading?
iron bearing minerals can record Earth's magnetic field direction. when Earth's magnetic field reverses, newly formed iron bearing minerals will record the magnetic reversal. magnetic reversals show new rock being formed at mid-ocean ridges. This helped explain how the crust could move
What techique is used to study ancient magnetic fields?
Paleomagnetism refers to the study of the record of the Earth's magnetic field preserved in various rocks and minerals through time.The study of paleomagnetism is possible because iron-bearing minerals such as magnetite may record past directions of the Earth's magnetic field when the rocks containing them were formed or last heated up.Paleomagnetic signatures in rocks can be recorded by three different mechanisms:-First, iron-titanium oxide minerals in basalt and other igneous rocks may preserve the direction of the Earth's magnetic field when the rocks cool through the "Curie temperature" for those minerals. (The Curie temperature of magnetite, is about 580°C).In a completely different process, magnetic grains in sediments may align with the magnetic field during or soon after deposition.In a third process, magnetic grains may be deposited from a circulating solution, or be formed during chemical reactions, and may record the direction of the magnetic field at the time of the mineral's formation.
How the ages of the rocks on the ocean floor support the theory of seafloor spreading?
iron bearing minerals can record Earth's magnetic field direction. when Earth's magnetic field reverses, newly formed iron bearing minerals will record the magnetic reversal. magnetic reversals show new rock being formed at mid-ocean ridges. This helped explain how the crust could move
How do rocks record the changes in the Earth's magnetic field?
When new seafloor is created by upwelling magma at the mid-ocean ridges, the magnetic minerals orient themselves to the magnetic orientation of Earth at the time of their solidification in the rock matrix. Thus, the history of magnetic reversals are recorded in the rock.
The magnetic record in the rock on the ocean floor depends on when the rock was?

What are the uses of a magnetic tape?
Magenetic tape drives are obsolete. They were used to record data on the magnetic tapes.The data was accessed sequentially.

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 causes Magnetic stripes on the seafloor are caused by?
These "stripes" formed the pattern known as magnetic striping. ... They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the magnetic reversals of the Earth's magnetic field.
