The figure represents the pattern of magnetism within the Juan de Fuca plate area. In the diagram on the right the gray bands represent parts of the seafloor that have normal magnetism, and seafloor magnetism is only shown for the Juan de Fuca plate, although similar patterns exist on the Pacific plate (see figure the left showing a broader context). Explain what is happening at the indicated plate boundaries and how the Juan de Fuca plate is evolving. Indicate the information that can be deduced from the paleomagnetism pattern shown.
