When new tectonic plate forms at divergent plate boundaries and gradually moves farther and farther away from the boundary, this is called

• mountain formation

• seafloor expansion

• seafloor spreading

• ridge formation

What clue did humans have to indicate seafloor spreading was happening?

• different patterns of animal and plant life on the seafloor

• magnetic stripes in ocean rocks

• unique type of crust formed in oceans only

• heat signatures in ocean rock

The Earth's magnetic field sometimes reverses itself

(north turns into south and south turns into north).

• True
