Evidence supporting seafloor spreading includes the symmetrical patterns of magnetic stripes on either side of mid-ocean ridges, which show reversals in Earth's magnetic field over time. Additionally, the age of oceanic crust increases with distance from the ridge, indicating that new crust is formed at the ridge and gradually moves outward. The presence of deep-sea sediments also supports this theory, as they are thinner and younger near the ridges and become thicker and older further away. Finally, the distribution of earthquakes and volcanic activity along mid-ocean ridges aligns with the movement of tectonic plates.

What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
What each cycle of spreading and intrusion of magma during seafloor spreading results in?
Taco.
What is least likely to result from seafloor spreading?
bananas :~P
What evidence in rocks supports the seafloor spreading hypothesis?
Magnetite, a mineral found in basalt, the rock that makes up the sea floor, has particles in it which align themselves with the polar alignment of the earth (North and South). Every once in a while, in Earth's history, the polar alignment switches (North becomes South, South becomes North) and so do the magnetite particles. Thus, there are matching bands on each side of a spreading center where the magnetite has switched as the rock came out of the spreading center.
Why did magnetic reversals on the seafloor support seafloor spreading?
Earth got its north and south Pole's have geographic and magnetic north and south poles which makes an angle of nearly 5.6degree. magnetic field created due to core of earth is reversed during each 100 million year period. ie.magnetic north becomes south and vice's. seafloor spreading is a continuous event so for each 100my spread seafloor we get opposite polarised magnetic substances. That is called magnetic reversal
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.

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.
What do magnetic anomalies provide evidence 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 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.
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 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

Animal fossils have been found in many places in the ocean.
