How do magnetic bands provide evidence that tectonic plates are moving apart at mid-oceanic ridges?
Through seafloor-spreading as iron rich minerals cool they become magnetized in the direction parallel to the existing magnetic field. As the magnetic fields change direction so will the magnetized minerals, allowing scientists to record each change in the seafloor as it spreads.
What else can I help you with?
Magnetic striping of evidence of?
Magnetic reversals and sea floor spreading.
How do earths magnetic pole reversals provide evidence for tectonics?
rocks get older as you move away from ocean ridges
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.
The best evidence of crustal movement is?
The best evidence of crustal movement is seismic activity, where earthquakes occur due to the shifting of tectonic plates underneath the Earth's surface. Geological features like mountains, rift valleys, and ocean trenches also provide evidence of crustal movement over long periods of time. Additionally, the alignment of magnetic minerals in rocks recording the past movements of the Earth's magnetic poles is another indicator of crustal movement.
Bands of magnetic material in the sea floor that have opposite poles or exhibit magnetic reversal can provide evidence for sea floor spreading true or false?
True. Bands of magnetic material in the sea floor that have opposite poles or exhibit magnetic reversal provide evidence for sea floor spreading. This is because as new oceanic crust forms at mid-ocean ridges, Earth's magnetic field periodically reverses, creating magnetic stripes on the ocean floor that align with the direction of the magnetic field at that time.
The magnetic particles in seafloor ridges are aligned differently in a repeating pattern How does this provide evidence for tectonic movement Why does it provide evidence?
Earth's magnetic field reverses over time; the changes show that seafloor has taken place over time.
How sea floor spreading provide evidence for tectonic plates?

What do magnetic anomalies provide evidence of?
seafloor spreading
Magnetic striping of evidence of?
Magnetic reversals and sea floor spreading.
How does magnetic reversals provide evidence for seafloor spreading?
Because of the stripes at the sea floor which are magnetic minerals
What evidence shows that earth's magnetic field changes?
One piece of evidence is the study of ancient rocks that show reversals in magnetic orientation. Another evidence comes from observations of the movement of the magnetic poles over time. Additionally, observations of magnetic anomalies in the Earth's crust provide further evidence of changes in the magnetic field.
