in magma and lava, there are magnetic minerals, called magnetite. When new magma reaches the surface, these minerals start to align with the existing magnetic 'field' around the earth, starting at the North pole, and ending at the South pole. once the magma cools, these minerals remain at this inclination. These rocks often form on the sea floor, where 2 plates are moving apart. Every 10,000 years (or so), the magnetic poles switch. So it would start at the south pole, to the north pole. This means the inclination of the minerals would swap in new magma. So as the sea continues to spread, there is a striped appearance on the sea floor, where the are symmetrical bands of alternating magnetically inclined rocks. Hope that helps :)

What century was South Pole mapped?
Until the early 1900s, there was no evidence that Antarctica was a solid continent, and the continent remained entirely unmapped until then. Be aware, however, that today, there are vast areas of Antarctica that are 'unmapped', except by satellite imagery.
Magnetic striping is evidence of?
pole reversals seafloor spreading
Magnetic Stripping is Evidence of?
pole reversals
What are Other than earth is also known to have magnetic pole reversals?
Other than Earth, Mars is also known to have experienced magnetic pole reversals in its history. Evidence from the planet's crust suggests that its magnetic field has reversed multiple times over millions of years, similar to Earth's magnetic field reversals.
Which body in our solar system magnetic pole reversals?

The sun's pole reversal is tied to the sunspot cycle.
What is used as evidence for sea floor spreading?
Magnetic reversals
How do earths magnetic pole reversals provide evidence for tectonics?

What is magnetic striping evidence of?
Magnetic reversals and sea floor spreading.
What Magnetic striping evidence of?
Magnetic reversals and sea floor spreading.
What is magnetic striping evidence?
Magnetic reversals and sea floor spreading.
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.
