Can seafloor stripes can be found on either side of all mid-ocean ridges?

Can seafloor stripes can be found on either side of all mid-ocean ridges?

The specific magnetism of basalt rock is determined by the Earth’s magnetic field when the magma is cooling. Scientists determined that the same process formed the perfectly symmetrical stripes on both side of a mid-ocean ridge. Oceanic crust slowly moves away from mid-ocean ridges and sites of seafloor spreading.

What do you observe about the magnetic stripe pattern on each side of the Oceanic Ridge?

What do you observe about the magnetic stripe pattern on each side of the oceanic ridge? The stripes are symmetric across the Oceanic Ridge.

How do the symmetrical magnetic reversal patterns of oceanic crust on either side of a mid-ocean ridge support the theory of plate tectonics?

How do the symmetrical age patterns of oceanic crust on either side of a mid-ocean ridge support the theory of plate tectonics? The patterns demonstrate that the oceanic crust is moving apart at a divergent plate boundary. Magma rises between two plates, cools, and creates new oceanic crust.

Is the magnetic stripe pattern represent?

Scientists discovered that the rock that makes up the ocean floor lies in a pattern of magnetized “stripes.” These stripes hold a record of reversals in Earth’s magnetic field. The rock of the ocean floor contains iron.

Why are the magnetic lineations identical on either side of the mid-ocean ridge?

Why are the magnetic lineations identical on either side of the mid-ocean ridge? -So, since the magma comes out on BOTH sides and moves outwards in BOTH directions, and acquires the prevailing magnetic field orientation….they are more or less identical on either side of the ridge.

Why are the magnetic stripes on either side of the ridge symmetrical to each other?

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.

Why are the magnetic lineations identical on either side of the mid ocean ridge?

What is the difference between mid-ocean ridges and trenches?

A mid ocean ridge is a divergent boundary where plates are moving apart, An ocean trench is a convergent boundary where plates are moving together.

Why is it important that your model have an identical pattern of stripes on both sides of the center slit?

Why is it important that your model have an identical pattern of strips on both sides of the center slit? The model has identical strips because, as the magma rises at the mid ocean ridge ½ goes to the right and ½ goes to the left of the mid ocean ridge. Each one of these strips represents Earth’s magnetic history.

What are the magnetic stripes of the mid ocean ridge?

At the mid-ocean ridge spreading axis, these flips in the direction of the Earth’s magnetic field are recorded in the magnetization of the lava. This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges.

How are magnetic patterns formed on the seafloor?

Magnetic patterns develop on the seafloor as basaltic lava erupts and cools, and iron-rich minerals align with Earth’s magnetic field If a magnetic stripe is 120 km wide and formed over 4 m.y., what would the rate of seafloor spreading be? 30 km/m.y.

What is the definition of a mid-ocean ridge?

Any trace of ancient organism that has been preserved in rock What is a mid-ocean ridge? An undersea mountain chain where new ocean floor is produced; a divergent plate boundary What is a deep-ocean trench? A deep valley along the ocean floor beneath which oceanic crust slowly sinks toward the mantle What is a sea-floor spreading?

How is the East Pacific Rise different from the Mid Atlantic Ridge?

Rapidly spreading ridges have a much more gentle slopes. The Mid-Atlantic Ridge, for instance, is a slow spreading center. It spreads 2-5 centimeters (.8-2 inches) every year and forms an ocean trench about the size of the Grand Canyon. The East Pacific Rise, on the other hand, is a fast spreading center.
