They proved that the seafloor was spreading.
Magnetic stripes on the seafloor provide evidence for seafloor spreading because they show alternating bands of normal and reversed polarity along mid-ocean ridges. These stripes form as new oceanic crust is created at mid-ocean ridges, with the Earth's magnetic field aligning minerals in the crust in the direction of the prevailing polarity at the time of its formation. By collecting and analyzing samples from the ocean floor, scientists can observe these magnetic patterns and confirm the process of seafloor spreading over geologic time scales.
Seafloor spreading provided evidence for continental drift by showing that new oceanic crust is formed at mid-ocean ridges, pushing older crust away. This process helped explain how continents could move and supported the idea of plate tectonics. The pattern of magnetic stripes on the seafloor also matched with predictions based on the movement of continents, further supporting the theory of continental drift.
The theory of seafloor spreading was not rejected; in fact, it is widely accepted in the field of geology. Proposed by Harry Hess in the early 1960s, seafloor spreading explains how new oceanic crust is formed at mid-ocean ridges and then moves away as tectonic plates drift apart. This concept revolutionized our understanding of plate tectonics and the Earth's geology.
ok so... over time, the magnetic poles kept changing directions. for example ur compass wuld suddenly turn the opposite direction. there was this type of rock(forgot the name) that always points the direction of the magnetic pole. this type of rock erupts from the bottom of the ocean floor. scientists found that the rocks at the ocean floor would change direction in order. like, one section of the rock would be pointing north, and one section would be pointing south, vice versa. they knew that since the rocks change directions, new ocean floor was forming and were pushing the continents away from each other. the sea was alos spreading. i used this 4 my hw u better not go 2 my middle school(chaparral)
They technically don't. They do provide evidence for it, however, in that they occur in pairs on either side of a rift, providing strong evidence that the rocks on either side were deposited at the same time and that the rifts are 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.
Magnetic stripes on the seafloor showed alternating patterns of normal and reversed polarity, matching Earth's magnetic field reversals. Age dating of seafloor rocks revealed that rocks were youngest along mid-ocean ridges and oldest near continental margins. Sediment thickness on the seafloor was thinnest at mid-ocean ridges and thickest near the continents, supporting the idea of seafloor spreading.
Tools such as sonar mapping, geologic sampling, and paleomagnetism studies were used to provide evidence for seafloor spreading. Sonar mapping allowed for the creation of detailed maps of the ocean floor, revealing features such as mid-ocean ridges and deep-sea trenches. Geologic sampling involved collecting rock samples from the ocean floor to study their age and composition. Paleomagnetism studies focused on analyzing the alignment of magnetic minerals in rocks, providing evidence of past changes in Earth's magnetic field that support the idea of seafloor spreading.

Magnetic minerals on the ocean floor.
Yes, seafloor spreading provided concrete evidence for the theory of continental drift proposed by Alfred Wegener. It demonstrated that new oceanic crust was continuously forming at mid-ocean ridges, pushing the continents apart over time. This supported the idea that continents were once connected and have since moved to their current positions.

How seafloor spreading helps to explain the theory of continental drift is that wegener couldn't explain why and waht force caused the continents to move and so seafloor spreading helps to explain the theory of continental drift because it shows the force that made the continents move and that was te only thing that wagener needed to prove his theory of continental drift............thanks
