Which of the following does NOT support the theory of plate tectonics?
A: Matching fossils from the same species on different present-day continents
B: Magnetic stripes on the ocean floor that cause Earth’s polarity to shift
C: Coastlines from different continents that match one another
D: Seafloor spreading that results in new crust
Answer (2)
The pattern of normal and reversed magnetization in seafloor basalt reflects polarity flips as lava cools, but the geodynamo in Earth’s core, not the crust, actually flips the poles .Magnetic stripes are records of Earth’s past magnetic-field reversals, not the driver of those reversals .
The correct answer is B: Magnetic stripes on the ocean floor that cause Earth's polarity to shift.Reason: Magnetic stripes are evidence of past polarity reversals, not the cause of them.
