On a map of the seafloor the boundaries between normally magnetized oceanic crust and reversely magnetized oceanic crust are called?
These boundaries are called magnetic anomalies, where the Earth's magnetic field has shifted relative to the seafloor rocks. These anomalies are used to study the history of plate tectonics and Earth's magnetic field reversals.
What is it called when rocks are different because Earths magnetic poles change places?
Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
Why are magnetic stripes parallel to mid ocean ridges?
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.
Which of these is the best evidence of seafloor spreading-ocean ridges-mid-oceanic mountains-volcanic islands-ocean trenches?
Ocean ridges is somewhat vague. Mid-ocean mountains are more precisely called mid-ocean ridges, so it seems like someone is trying to trip you up. The best evidence of seafloor spreading among the choices would be mid-ocean mountains. They are the buoyant, hot, new crust that is formed at the divergent plates of the world's oceans.
How do parallel stripes near mid-ocean ridges 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.

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
What are earths alternating magnetic bands called?
Earth's alternating magnetic bands are called magnetic reversals or geomagnetic reversals. These reversals are periods in Earth's history where the magnetic field flips, with the north and south magnetic poles reversing positions. They can be detected in the rock record and provide valuable information about Earth's geological history.
How do magnetic reversals provide evidence for sea-floor spreading?
The presence of magnetic domains of alternating orientation parallel to the plate boundaries.

Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
How do the parallel magnetic stripes near mid ocean ridges?

How do the parallel magnetic 'stripes' near mid-oceanic ridges 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.
