How do ocean basin magnetic reversals prove plate tectonics exists?

They technically don't. They do provide evidence for it, however, in that they occur in pairs on either side of a rift, providing strong evidence that the rocks on either side were deposited at the same time and that the rifts are spreading.

Do ocean basin spread uniformly over the entire basin?
no, think about plate tectonics, and what they may form....
Large or small depression in the land or ocean floor?
A basin is a large or small depression in the surface of land. or the ocean. A basin can be caused by plate tectonics or erosion.
Strips of alternating magnetic polarities found in rocks in the ocean basin?
provide evidence for sea-floor spreading
What is a example of basin landform?
No. Basalt is a kind of rock. There can be landforms made of basalt, but it isn't a landform in and of itself.
What is low area surrounded by higher land?
its called a basin

What is the pattern of magnetic polarity reversals?
In a geomagnetic reversal, the south and north magnetic poles flip locations. A magnetic pole reversal takes place every 450,000 years on average, but this is not regular. We are way overdue since the last reversal was 780,000 years ago. There is a pattern in the magnetic polarity of basaltic rocks on opposite sides of a mid-ocean ridge. Basalt contains tiny magnetic crystals that point to the location of the north magnetic pole at the time the lava cools. The rocks at the ridge have positive polarity, but on either side of the ridge the polarity is negative, indicating that those lavas cooled when the magnetic field was opposite of what it is today. On either side of the basalt with negative polarity are more rocks with positive polarity. This pattern continues on both sides of the mid-ocean ridge across the ocean basin. The pattern of magnetic polarity is one of the main lines of evidence for seafloor spreading, which is the mechanism for plate tectonics.

What is a rift basin?
Rift basins are depressions within the crust and lithosphere that are associated with extensional tectonics. The presence of active normal faulting itself, creates the accomodation space for sedimentary infill within grabens and half graben structures.
