The direction of the Earth's magnetic field has reversed several times during its history. This causes the North magnetic pole to become a South magnetic pole and vice versa. We know this because of the direction of magnetism in the rocks on the ocean floor, which alternates in 'stripes' on either side of the mid-ocean ridges.

Which body in our solar system magnetic pole reversals?
the sun
Phenomenon of the Earth's magnetic pole being in different locations in the past?
There are two phenomena:-polar wanderingmagnetic reversals
How often do earth magnetic poles reverse?
Time periods between Earth's magnetic pole reversals are varied. There are geologic periods where multiple reversals have occurred and periods of no activity. In the last 3.6 million years, there have been at least nine reversals, the last occurring 730,000 years ago.
Do the earth's magnetic poles have reversed themselves?
Yes, in the history of Earth, it has happened a handful of times. When it switches we experience what we call a pole reversal. Right now Earth is currently in the process of a pole reversal (the South Pole is moving northwards).
Which pole is located in an ocean?
Deep-sea geology has shown that the flows of rock out of faults underwater, particularly at the Mid-Ocean Ridge in the Atlantic Ocean, has layers of magnetically different composition. From these, we also learn of the extent and timing of the pole reversals due to geological dating techniques.
Magnetic striping is evidence of?
pole reversals seafloor spreading
Magnetic Stripping is Evidence of?
pole reversals
Which body in our solar system has a magnet pole reversals?
The sun
Which body in our solar system magnetic pole reversals?
the sun
The sun's pole reversals are tied to its?
The sun's pole reversal is tied to the sunspot cycle.
Which body in your solar system has magnetic pole reversals?
The sun
The suns reversals are tied to it's?
The sun's pole reversal is tied to the sunspot cycle.
What is the result of Magnetic reversals?
The north pole becomes the south pole and vice versa. Also any rocks cooling in the reversed field will trap the magnetic polarity prevalent at their time of cooling. This means we can can trace the history of past magnetic reversals.
Why do earth magnetic pole reversals provide for plate tectonics?
Rocks lock in their magnetism when they cool.
Phenomenon of the Earth's magnetic pole being in different locations in the past?
There are two phenomena:-polar wanderingmagnetic reversals
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
What are paleomagnetism and magnetic field reversals?
Paleomagnetism refers to the strength and orientation of the earth's magnetic field at some remote past time. Magnetic field reversals are recorded in deep ocean bottom materials which show that at some ancient times the earth's magnetic poles have reversed, north pole becoming south pole and south pole becoming north pole.
