Homework Statement
(Picture attached)
How does the process of sea-floor spreading produce these orientations and relationships [between the ages of magnetic stripes and the distance from the ridge crests, as well as the parallel direction of the magnetic stripes with those of the ridge axes]?
Why are some magnetic stripes wider than others?
Homework Equations
I don't think I need any.
The Attempt at a Solution
Don't need answers, just help!
1. I'm guessing that the older magnetic stripes are furthest away from the ridge axes because sea-floor spreading is pushing them away. I don't know why the magnetic lines are parallel to the ridge axes though.
2. I have no idea why some stripes are wider than others, does it have to do with sea-floors' surface features?
