The rocks on either side of a mid-ocean ridge record the direction of the Earth's magnetic field at the time they were formed, and form a pattern of 'magnetic stripes' on either side of the ridge which are symmetrical. It is also now possible to measure ocean widths with sufficient accuracy to show yearly changes.

What do magnetic anomalies provide evidence of?
seafloor spreading
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic Ridge
How are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
What is the evidence of seafloor spreading?
Animal fossils have been found in many places in the ocean.
What is the modern theory supported by additional evidence such as satellite measurements of continental movement?
Seafloor Spreading.
What do magnetic anomalies provide evidence of?
seafloor spreading
How is magnetism used to support the theory about seafloor spreading?
Magnetism is used to support the theory of seafloor spreading through the study of magnetic stripes on the seafloor. These stripes are aligned with the Earth's magnetic field and provide evidence for the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, the magnetic minerals in the rocks align with the Earth's magnetic field, creating a record of magnetic reversals over time that support the theory of seafloor spreading.
Magnetic striping is evidence of?
pole reversals seafloor spreading
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic Ridge
How were earthquake patterns used to provide evidence of seafloor spreading?
Earthquake patterns were used to provide evidence of seafloor spreading through the discovery of mid-ocean ridges. Scientists observed that earthquakes were concentrated along these ridges, indicating the presence of tectonic activity associated with the movement of tectonic plates. This supported the theory of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges and pushes older crust away from the ridge.
How do the ages of the rocks on the seafloor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
How are magnetic patterns in sea floor rock evidence of seafloor spreading?
Magnetic alignment of rocks, in alternating strips that run parallel to ridges, indicates reversals in Earth's magnetic field and provides further evidence of seafloor spreading.
How did the seafloor drilling help scientist find evidence to support the seafloor-spreading hypothesis?
people here are stupid , really the answer is not hi
How did seafloor drilling scientists find evidence to support the seafloor-spreading hypothesis?
dumb question. don't want to write it all
What is the evidence of seafloor spreading?
Animal fossils have been found in many places in the ocean.
Is there evidence that seafloor-spreading?
Yes, there is evidence supporting seafloor spreading, including magnetic striping patterns on the ocean floor, the age progression of seafloor away from mid-ocean ridges, and the presence of hydrothermal vents along mid-ocean ridges that release magma from the Earth's mantle.
What evidence in rocks supports the theory seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.
