Why do bands indicating magnetic reversals appear to be of similar width on both sides of a mis ocean ridge?
The similar width of magnetic reversal bands on both sides of a mid-ocean ridge is due to the symmetrical process of seafloor spreading. As magma rises and cools at the ridge, it records the Earth's magnetic field orientation at that time. The consistent rate of seafloor spreading on either side of the ridge ensures that the width of these bands is uniform, reflecting the periodic nature of magnetic reversals. Thus, the bands form parallel patterns that mirror each other across the ridge.

Why do bands indicating magnetic reversals appear to be similar width on both sides of a mid-oceanridge?
Bands indicating magnetic reversals appear similar in width on both sides of a mid-ocean ridge because they are formed simultaneously as magma rises and solidifies at the ridge, creating new oceanic crust. The Earth's magnetic field undergoes periodic reversals, and as the molten rock cools, it records these magnetic orientations. Since the process of seafloor spreading occurs uniformly on both sides of the ridge, the resulting magnetic stripes are symmetrical in width and spacing, reflecting the consistent rate of magma flow and cooling.
What do the earths magnetic poles move around?
This happens about once every 50 to 100 thousand years and is called a magnetic reversal.It would appear that the self generated magnetic fields formed by rotating bodies all undergo pole reversals. For instance the Sun does this about every 11 years.
What pattern of striping at a mid ocean ridge would you expected find if the magnetic polarity changed many times over a short period?
If magnetic polarity changed many times over a short period at a mid-ocean ridge, you would expect to find a complex pattern of striping on either side of the ridge. Instead of the typical symmetrical, alternating bands of normal and reversed polarity, the stripes would appear irregular and fragmented, indicating rapid and multiple reversals. This chaotic pattern would reflect the tumultuous geological activity in the area, complicating the interpretation of the magnetic history. Overall, the striping would likely be less distinct and more varied than in areas with more stable magnetic reversal timelines.
Sun spots sit on the suns?
Sunspots are temporary dark spots on the Sun's surface caused by magnetic activity that inhibits the flow of heat. They are cooler and appear darker than the surrounding area of the Sun, indicating intense magnetic activity. Sunspots can vary in size and shape and typically last for a few days to a few weeks.
Why do magnetic stripes appear on the seefloor?
The seafloor spreads apart, creating new rocks that record magnetic orientation. Small grains of magnetite on the volcanic basalt (ocean floor) have magnetic properties.

Why do bands indicating magnetic reversals appear to be of similar width on both sides of a mid-ocean ridge?
They appear to be similar in width because new crust formation is nearly equal on each side of the fault.

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.

Why do sunspots appear?
Sunspots appear because of the magnetic fields, they appear black because they're slightly cooler than the surface of the rest of star.
Why do magnetic stripes appear on the seefloor?
The seafloor spreads apart, creating new rocks that record magnetic orientation. Small grains of magnetite on the volcanic basalt (ocean floor) have magnetic properties.
Why do magnetic stripes appear on the sea?
The seafloor spreads apart, creating new rocks that record magnetic orientation. Small grains of magnetite on the volcanic basalt (ocean floor) have magnetic properties.
What connects 2 sunspots?
Sunspots are areas on the sun's surface where magnetic activity inhibits convection, causing them to be cooler and appear darker than their surroundings. The connection between two sunspots is a shared magnetic field. Sunspots often appear in pairs or groups, with oppositely charged magnetic fields connecting them.
Why do magnetic strips appear on the sea floor?
Magnetic stripes on the sea floor form as a result of the movement of tectonic plates. When magma rises to the surface at mid-ocean ridges and solidifies into new rock, it records the Earth's magnetic field at the time. This creates alternating stripes of normal and reversed polarity as the Earth's magnetic field has flipped multiple times throughout history.
