The magnetic particles in seafloor ridges are aligned differently in a repeating pattern. how
does this provide evidence for tectonic movement? it provides evidence because the
a. earth's magnetic field reverses over time;
the changes show that seafloor spreading
has taken place over time.

b. magnetic particles in seafloor ridges don't
provide evidence for the movement of
tectonic plates.

c. movement of tectonic plates creates a
magnetic field which magnetizes the particles
as the plates move.

d. magnetic field of tectonic plates changes
lavor time
