What are three kinds of evidence scientists have found to support ocean floor spreading?
Oh, dude, scientists have found magnetic striping, age dating of rocks, and the distribution of earthquakes and volcanoes along mid-ocean ridges to support ocean floor spreading. It's like Mother Nature left us some breadcrumbs to follow, you know? So, yeah, those are the three main pieces of evidence that point to the fact that our ocean floors are actually moving and grooving.

Granitic strips in the ocean floor ... Novanet
Used as evidence for sea-floor spreading?
Magnetic striping on the ocean floor is used as evidence for seafloor spreading. As new oceanic crust forms at mid-ocean ridges, Earth's magnetic field is recorded in the rocks in alternating patterns of normal and reversed polarity. This provides support for the idea that new crust is continuously being created at mid-ocean ridges and spreading away in opposite directions.
What do magnetic reversals help support?
Magnetic reversals in Earth's history help support the theory of plate tectonics by providing evidence of seafloor spreading and the movement of lithospheric plates. They also assist in dating rocks and determining the age of oceanic crust.
What evidence do scientists have to support the idea that the continents were once one large land mass?
Scientists support the idea of a supercontinent called Pangaea through evidence such as matching coastlines, similar rock formations, and identical fossils found on different continents. Additionally, the movement of tectonic plates, as recorded by magnetic anomalies in the ocean floor, provides further support for the theory of continental drift.
How do scientists prove seafloor spreading?
Scientists prove seafloor spreading through various methods, including mapping of magnetic stripes on the ocean floor, analysis of seismic activity, and examination of rock samples collected from the ocean crust. These techniques provide evidence of tectonic plate movement and the creation of new oceanic crust at mid-ocean ridges.
Is the analysis of seafoor sediments evidence of sea-floor spreading?
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

What kinds of magnetism did scientists finds while studying the ocean floor?
Scientists found evidence of magnetic stripes on the ocean floor, which indicated periodic reversals in Earth's magnetic field. This discovery helped support the theory of plate tectonics and seafloor spreading.
What are three types of evidence provided support for sea-floor spreading?
Seismic Waves, Rock formations, and the shapes of the continents over time
What is sea floor spreading and what evidence do we have to prove it is happening?
Magnetic minerals on the ocean floor.
What is used as evidence for sea floor spreading?
Magnetic reversals
How do the ages of the rocks on the ocean floor 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 do the ages of rock on the ocean floor 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 three types of evidence provided support of the theory of sea-floor spreading?
three are : eruptions of molten material magnetic stripes in the rock of the ocean floor and the ages of the rocks themselves :)

What discovery led scientists to accept Wegeners continental drift hypothesis?
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.
What evidence is there to support the theory of sea floor spreading?
the newer rock is closer to the middle n th older ones spread along the sides
