Other than abundant matching fossils and sedimentary rock on opposite sides of the Atlantic Ocean and the apparent puzzle piece appearance of the continents on either side of the Atlantic, there is the presence of the mid-oceanic ridges, areas where new oceanic crust is created. The magnetic orientation of the basaltic oceanic crust as it forms is the mirror image of the magnetic orientation of the basaltic oceanic crust on the other side of the ridge, indicating that the seafloor is spreading in both directions away from ridge. Additionally, the dating of rock on the ocean floor has shown that oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached.
And finally, accurate measurements have been made by global positioning devices which verify that seafloor spreading is occurring.
What else can I help you with?
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 ocean-floor rocks and sediments evidence of seafloor spreading?
Ocean-floor rocks near mid-ocean ridges show a symmetrical pattern of magnetized stripes parallel to the ridge axis. These stripes result from periodic reversals in Earth's magnetic field and provide evidence of seafloor spreading. Sediments on the ocean floor also show younger ages near the ridges, supporting the idea 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.
Give two pieces of evidence for seafloor spreading?
Paleomagnetic stripes on either side of mid-ocean ridges demonstrate the symmetric pattern of magnetic reversals found in oceanic crust, supporting the idea of seafloor spreading. Age dating of oceanic crust samples reveals that the further away from mid-ocean ridges, the older the crust gets, providing direct evidence for the continuous creation of new seafloor at spreading centers.
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.
What is the evidence of seafloor spreading?
Animal fossils have been found in many places in the ocean.
What do magnetic anomalies provide evidence of?
seafloor spreading
What are 3 things of evidence that scientists have that prove the ocean is spreading?
1) seafloor spreading 2) continental drift 3 i only found 2
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 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
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.
How are ocean-floor rocks and sediments evidence of seafloor spreading?
Ocean-floor rocks near mid-ocean ridges show a symmetrical pattern of magnetized stripes parallel to the ridge axis. These stripes result from periodic reversals in Earth's magnetic field and provide evidence of seafloor spreading. Sediments on the ocean floor also show younger ages near the ridges, supporting the idea of seafloor spreading.
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.
