Why are the magnetic stripes equal on both sides of the ocean ridge?

Why are the magnetic stripes equal on both sides of the ocean ridge?

When lava gets erupted at the mid-ocean ridge axis it cools and turns into hard rock. As it cools it becomes permanently magnetized in the direction of the Earth’s magnetic field. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges.

What do the stripe patterns in the paper represent?

The strips of paper represent oceanic crust or seafloor. Seafloor spreading is the creation of new seafloor or new oceanic crust 5. The earth does not get bigger.

Are those stripes the same on both sides of the ridge?

More support came when scientists discovered that the rock that makes up the ocean floor lies in a pattern of magnetized “stripes. The pattern is the same on both sides of the ridge. These stripes hold a record of reversals in Earth’s magnetic field.

How does the pattern of magnetic stripes give evidence for seafloor spreading?

How do strips of magnetized rock on the ocean floor provide evidence of sea-floor spreading? Strips of ocean-floor basalt record the polarity of Earth’s magnetic field at the time the rock formed. The pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.

Why are magnetic patterns found on ocean floor?

These surveys revealed a series of invisible magnetic “stripes” of normal and reversed polarity in the sea floor, like that shown in the figure below. The patterns reflect the creation and spreading of oceanic crust along the mid-oceanic ridges. Basalt forming at the ridge crest picks up the existing magnetic polarity.

What process happens at the two side slits represent *?

Answer: Side Slits are the resultant of subduction, a geological process wherein a tectonic plate mobes under another plate. In addition, the subducting plate is one that goes under the other platex which is called overriding plate.

What are you modeling by pushing the strips through the base?

What are you modeling by pushing the strips up through the base? The moving of new material from the athenoshpere through the crack litmosphere.

What is the importance of seafloor spreading in understanding the origin of the plate?

Significance. Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere.

What does this pattern suggest about how the seafloor forms?

The stripes are symmetric across the Oceanic Ridge. It suggests that new seafloor is formed in the middle (at the Ridge) and some of the new seafloor moves to each side of the Ridge forming a symmetric pattern.
