of seafloor formed at different times on an earth whose magnetic polarity occasionally
reverses through geologic time.

E.A chocolate covered cherry, it is solid at the core surrounded by a liquid layer and
semi-solid layer, then covered in a thin solid coating. - Answer- E.A chocolate covered
cherry, it is solid at the core surrounded by a liquid layer and semi-solid layer, then
