Does geomagnetic reversals represent a source of information on the rate of sea-floor spreading?
As mid ocean ridges create new seafloor over extended periods of time, the magnetic poles of the Earth reverse back and forth. The rocks on either side of a mid ocean ridge show the opposite magnetisms and appear striped. From knowing the approximate ages of these magnetic reversals, one can estimate the approximate age of each stripe.

What do magnetic reversals help support?
Magnetic reversals in Earth's history help support the theory of plate tectonics by providing evidence of seafloor spreading and the movement of lithospheric plates. They also assist in dating rocks and determining the age of oceanic crust.
Sensing device that detects magnetic fields helping confirm seafloor spreading?
A magnetometer is a sensing device that detects magnetic fields and is commonly used to measure magnetic anomalies on the seafloor. By mapping these anomalies, geologists can confirm the process of seafloor spreading by identifying patterns of magnetic stripes that align with known geomagnetic reversals. This data provides valuable evidence for plate tectonics and the movement of Earth's crustal plates.
How do the parallel magnetic stripe near mid ocean ridge form?
These stripes often called zebra stripes, due to the alternating colors of the original magnetometer readings. When the first observations were made, it is directly related to two processes geomagnetic reversals and seafloor spreading.
What is the spreading of information to convince others of an idea?
The spreading of information to convince others of an idea is known as persuasion. This can involve using various communication strategies and techniques to influence someone's beliefs, attitudes, or behaviors towards a particular perspective or viewpoint.
How is magnetism used to support the theory about seafloor spreading?
Magnetism is used to support the theory of seafloor spreading through the study of magnetic stripes on the seafloor. These stripes are aligned with the Earth's magnetic field and provide evidence for the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, the magnetic minerals in the rocks align with the Earth's magnetic field, creating a record of magnetic reversals over time that support the theory of seafloor spreading.
