# How do the parallel magnetic stripes near mid-ocean ridges form quizlet?

## How do the parallel magnetic stripes near mid-ocean ridges form quizlet?

Explain why magnetic strips on the seafloor are parallel to the mid-ocean ridge. New rock is formed when lava erupts along the length of the ridge. When the seafloor spreads, this rock separates and moves in opposite directions, forming lines that are parallel to the ridge.

How do magnetic stripes of iron in ocean rock?

How do magnetic stripes of iron in ocean rock provide evidence of seafloor spreading? They show how the density of the seafloor has changed. They reveal a matching pattern on either side of the ridge. They reveal differences in the mineral composition of newly created rock.

### What are the formation of magnetic strips?

The striped magnetic pattern develops because, as oceanic crust pulls apart, magma rises to the surface at mid-ocean ridges and spills out to create new bands of ocean floor.

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.

#### What leads to the formation of magnetic stripes on the seafloor quizlet?

As you move further away from the ridge crests, the age of the magnetic stripes increases. This is due to the process of seafloor spreading that creates new crust and pushes the old crust away. When seafloor spreading occurs, plates move away from one another at the axis if the midocean ridge.

Why are magnetic stripes on the seafloor parallel?

They are parallel because each magnetic stripe represents crust that formed and magnetized at a mid-ocean ridge during a period of either normal or reversed polarity.

## How do magnetic strips of iron in ocean rock provide evidence of seafloor spreading Brainly?

Answer: They show how the density of the sea floor has changed. They reveal a matching pattern on either side of the ridge . They reveal differences in the mineral composition of newly created rock.

How are magnetic stripes formed on the ocean floor?

Over time, the Earth’s magnetic field reverses its north-to-south polarity, and the magnetic minerals point in the opposite direction, creating a striped pattern. The discovery of magnetic stripes on the seafloor in the 1950s validated the plate tectonics theory for the geological community.

### What are the magnetic patterns of mid ocean ridges?

This creates a symmetrical pattern of magnetic stripes of opposite polarity on either side of mid-ocean ridges. These patterns of stripes provide the history of seafloor spreading. Geophysicists can read these patterns from the magnetic anomalies they measure with a magnetometer.

What happens to lava at the mid 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.

#### Are there two long stripes with normal magnetism?

There is one long stripe with normal magnetism at the top of the ridge. Next to that stripe are two long stripes with reversed magnetism. One is on either side of the normal stripe.
