Question

Movie Question: In order to produce the pattern of magnetic stripes that was

discovered in the 1950's the seafloor had to spread out.
True
False

Answer 1

False. The pattern of magnetic stripes on the seafloor supports the theory of plate tectonics.

Step-by-step explanation:

False

The pattern of magnetic stripes on the seafloor was discovered in the 1950s. This pattern provided evidence for the theory of plate tectonics. According to this theory, the seafloor spreads apart at mid-ocean ridges, forming new crust. As new crust is formed, rocks on either side of the ridge record the Earth's magnetic field at the time of their formation, creating a mirror image of magnetic stripes.

These magnetic stripes have been found on seafloor crust around the world, supporting the idea that the continents are not fixed, but rather in constant motion.
