What concepts did magnetic striping reveal to scientists about the rock on either side of a spreading ridge?
The pattern of magnetic striping on one side of the ridge was a mirror image of the striping on the other side of the ridge, indicating that the plates were moving equally in opposite directions, giving a plausible explanation for continental drift theory. Before this discovery, no evidence of a mechanism for plate tectonics existed. It was obvious after this discovery, that new crust was being created at the ridges.

Magnetic striping of evidence of?
Magnetic reversals and sea floor spreading.
What structure on the seafloor would have magnetic striping?
A mid-ocean ridge would have magnetic striping on the seafloor. This striping is caused by the alternating polarities of Earth's magnetic field recorded in the basaltic rocks as they cool and solidify at the mid-ocean ridge, providing evidence for seafloor spreading.
How were different groups of scientists involved in the research and discovery of seafloor spreading?
Different groups of scientists, including geophysicists, geologists, and oceanographers, contributed to the research and discovery of seafloor spreading in the mid-20th century. Geophysicists like Harry Hess proposed the theory based on evidence such as magnetic striping on the ocean floor. Geologists like Fred Vine and Drummond Matthews further supported the theory with their work on marine magnetic anomalies. Oceanographers collected data from the seafloor to provide additional evidence for seafloor spreading.
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 scientists now know about earth that would have answered the scientists who rejected wegeners theory?
Scientists now know about plate tectonics, which explains how Earth's outer shell is divided into large plates that move and interact with each other. This understanding supports Wegener's theory of continental drift, as it provides a mechanism for the movement of continents over time. Additionally, evidence from ocean floor mapping, seafloor spreading, and magnetic striping further supports the concept of plate tectonics.

Magnetic striping is a part of?
Magma contains many materials which are magnetically affected. When this magma is ejected from the mantle and begins forming new crust, these materials align to the earth's magnetic field. The crust hardens, and the magnetic alignment is fixed (just as in normal magnets, made by using a similar process). The magnetic fields are 'visile' in strips of material, hence the term 'magnetic striping'. seafloor spreading
What causes the magnetic striping noticed about the mid ocean ridges?
These "stripes" formed the pattern known as magnetic striping. ... They hypothesized that the magnetic striping was produced from the generation of magma at mid-ocean ridges during alternating periods of normal and reversed magnetism by the magnetic reversals of the Earth's magnetic field.
What does magnetic striping tell us about the age of rocks?
If you know how many stripes away from the mid-ocean ridge the rock is and you know how frequently the earth's poles flip you can use the stripes like rings on a tree to measure the age of that rock.
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.
How seismic studies support seafloor spreading?
Seismic studies show evidence of mid-ocean ridges where new oceanic crust is forming, supporting the theory of seafloor spreading. By analyzing seismic waves, scientists can map the structure of the ocean floor and identify areas of tectonic activity where plates are moving apart. Additionally, seismic data reveals the presence of magnetic striping on the seafloor, further supporting the idea of seafloor spreading.
