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.
What else can I help you with?
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.
First related the symmetrical magnetic patterns in seafloor basalts to seafloor spreading at a mid-ocean ridge?
Lawrence W. Morley, Frederick John Vine, and Drummond Hoyle Matthews were the first to tie magnetic stripe anomalies to seafloor spreading. The magnetic anomalies was the first evidence that supported the theory of seafloor spreading.
How do earthquake patterns show evidence for sea floor spreading?
Earthquake patterns along mid-ocean ridges show a linear distribution parallel to the ridge axis, indicating that earthquakes occur as the seafloor spreads apart. The earthquakes are caused by the movement of tectonic plates diverging at the ridge, creating tensional stress that results in seismic activity. This pattern of earthquakes along mid-ocean ridges provides direct evidence for sea floor spreading as part of plate tectonics.
What is the primary evidence that forms the basis of seafloor spreading?
The primary evidence for seafloor spreading comes from magnetic striping patterns on the ocean floor. These patterns show alternating bands of normal and reversed polarity, indicating that new oceanic crust is being continuously formed at mid-ocean ridges and spreading away from the ridge axis.
How does seafoor age and magnetic clues support seafloor spreading?
Seafloor is youngest near the mid-ocean ridges and gets progressively older as you move away from the ridge. Magnetic stripes on the seafloor provide evidence of seafloor spreading, as they show alternating patterns of normal and reversed magnetic polarity that match the Earth's magnetic reversals over time. This supports the theory of seafloor spreading as new oceanic crust is created at the mid-ocean ridge and spreads outward.
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.
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.

pole reversals seafloor spreading
What is one phenomenon that is considered evidence of seafloor spreading?
The Mid Atlantic 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 did the seafloor drilling help scientist find evidence to support the seafloor-spreading hypothesis?
people here are stupid , really the answer is not hi
