How can magnetic symmetry can be used as evidence of seafloor spreading?
Magnetic symmetry refers to the pattern of magnetic anomalies found on either side of mid-ocean ridges, where the Earth's magnetic field has reversed over geological time. As magma rises and solidifies at these ridges, it records the Earth's magnetic orientation, creating symmetrical patterns of magnetic stripes on the seafloor. This symmetry indicates that new oceanic crust is continuously being created and pushed outward, supporting the theory of seafloor spreading. The parallel arrangement of these magnetic anomalies on either side of the ridge provides evidence of the age and movement of tectonic plates.
How did the new evidence support Hess's theory of seafloor spreading?
The new evidence provided observations of magnetic anomalies on the seafloor that were consistent with the pattern predicted by Hess's theory of seafloor spreading. These anomalies demonstrated symmetrical stripes of magnetic polarity on either side of mid-ocean ridges, supporting the idea that new oceanic crust was forming at these ridges and moving away in opposite directions.
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 is Rocks on the sea floor that lie in a pattern. Show a record of the reversals of earths?
Rocks on the seafloor that lie in a pattern, showing a record of Earth's magnetic reversals, are known as magnetic anomalies. These anomalies occur due to the periodic flipping of Earth's magnetic field, which is recorded in the igneous rocks formed at mid-ocean ridges. As magma cools and solidifies, magnetic minerals within the rock align with the current magnetic field, creating a distinct pattern of magnetic "stripes" that mirror each other on either side of the ridge. This phenomenon provides crucial evidence for the theory of plate tectonics and seafloor spreading.

Mid-Ocean Ridges
When were Mid-Ocean ridges first discoerverd?
The Mid-Ocean ridges were first discovered in the 1950's
How do earths magnetic pole reversals provide evidence for plate tectonics?
Magnetic stripes can be seen as you move away from ocean ridges.

What do the strips of rocks with their magnetic poles pointing in the opposite direction to Earth and magnetic poles represent on the ocean floor?
The strips of rocks with their magnetic poles pointing in the opposite direction to Earth's magnetic poles represent the phenomenon of magnetic reversal, which occurs when Earth's magnetic field changes direction. These alternating stripes are found on the ocean floor, particularly at mid-ocean ridges, and are evidence of seafloor spreading. As magma rises and cools at these ridges, it records the Earth's magnetic field at that time, creating a pattern of magnetic anomalies that reflects the history of geomagnetic reversals. This pattern helps scientists understand the age of the oceanic crust and the processes of plate tectonics.
How were the mid-ocean ridges discovered?
by using sound waves
What causes the magnetic striping noticed about the mid ocean ridges?

The seafloor magnetic pattern is best described as?
parallel to and symmetric about ocean ridges
What discovery about the the ocean floor is associated with the seafloor spreading?
Seafloor spreading, a key concept in plate tectonics, was significantly supported by the discovery of mid-ocean ridges and the symmetrical patterns of magnetic anomalies on either side of these ridges. As magma rises and solidifies at the ridges, it creates new oceanic crust, pushing older crust away. This process also revealed that the ocean floor is constantly renewing itself, contributing to our understanding of continental drift and the dynamic nature of Earth’s geology.

The pattern of magnetic reversals along the sides of mid-ocean ridges resembles?
The pattern of magnetic reversals along the sides of mid-ocean ridges resembles stripes that alternate in polarity, created as new oceanic crust is formed at mid-ocean ridges and records the Earth's changing magnetic field. These magnetic stripes provide evidence for seafloor spreading and plate tectonics.
