The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
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.
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.
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.
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.
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.
Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading

seafloor spreading
Seafloor spreading is supported by the observation that sediments are thinner and younger near mid-ocean ridges, where new crust is formed, and become progressively thicker and older as one moves away from the ridge. This pattern indicates that as new oceanic crust is created at the ridge, it pushes older crust outward, allowing sediment to accumulate over time. Additionally, the age of the sediments correlates with their distance from the ridge, providing strong evidence for the continuous process of seafloor spreading.

The Mid Atlantic Ridge
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.
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.
people here are stupid , really the answer is not hi
dumb question. don't want to write it all
Animal fossils have been found in many places in the ocean.
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.
