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.
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 does the age of rocks in the seafloor provide evidence of seafloor spreading?
The age of rocks gets progressively younger as you move away from the mid-ocean ridges, where seafloor spreading occurs. This supports the theory of seafloor spreading, as new crust is being formed at the ridges and then moves away from them over time. This process leaves a record of older rocks further from the ridges and younger rocks closer to them.
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.
What do magnetic anomalies provide evidence 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 do the ages of the rocks on the seafloor support the theory of seafloor spreading?

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.
