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.

Which evidence causes most scientists to believe that seafloor spreading occurs at the mid-atlantic ridge?
The presence of magnetic stripes on either side of the mid-Atlantic ridge supports the theory of seafloor spreading. These stripes align with Earth's magnetic field reversals recorded in rock formations, indicating that new crust is constantly being formed at the ridge, pushing older crust away. Additionally, age dating of seafloor rocks shows that crust near the ridge is much younger than crust farther away, confirming the process of seafloor spreading.
How would the history of magnetic reversals show it self on the ocean floor?
It indicates that the crust is growing equally over time on either side of a mid-ocean divergent plate boundary. The magnetic orientation indicates the direction of the magnetic pole at the time the rock's magnetic minerals solidified from lava or magma.
What kind of activity causes seafloor spreading?
Seafloor spreading is caused by the movement of tectonic plates away from each other at mid-ocean ridges. As the plates separate, magma rises to the surface, solidifies, and creates new oceanic crust. This process is part of the theory of plate tectonics.
What was the primary force that causes the seafloor to spread and continents to drift?
The primary force driving seafloor spreading and continental drift is mantle convection. Heat from Earth's core causes the mantle to circulate, creating convection currents that move tectonic plates, leading to the spreading of the seafloor and movement of continents.
What is the primary force that cause the seafloor to spread and continental to drift?
The primary force that causes the seafloor to spread and continents to drift is plate tectonics. This process is driven by the movement of molten rock in the Earth's mantle, which generates forces that push apart tectonic plates, leading to seafloor spreading and continental drift.
What causes paleomagnetic patterns on the seafloor?
Paleomagnetic patterns on the seafloor are caused by the movement of tectonic plates. As the seafloor spreads at mid-ocean ridges, molten rock solidifies to form new crust containing minerals aligned with the Earth's magnetic field. Over time, Earth's magnetic field reverses, leaving a record of these changes in the seafloor's magnetic stripes.

What Causes of magnetic striping?
Magnetic striping on the ocean floor is caused by the movement of tectonic plates. As new oceanic crust is formed at mid-ocean ridges, Earth's magnetic field causes iron-rich minerals in the crust to align and record the direction of the magnetic field at that time. This results in alternating patterns of magnetic polarity stripes on the ocean floor.
What causes magnetic fields?
It is caused by moving electric currents>
What do earths magnetic stripes indicate about ocean crust?
reversed itself in the pastThe alternating magnetic orientation is caused by polar shifts or reversal, (not end of the world kinda stuff). When the rock is new and molten the grains are free to align themselves with the prevailing magnetic field, as the rock cools, the grains are frozen in time. As the sea floor expands outward (in the Atlantic), it is regularly striped with rock oriented in different directions. This indicates that the magnetic poles have reversed many times throughout the Earth's history.
What are the causes of magnetic drift?
Magnetic drift can be caused by changes in the Earth's magnetic field, variations in the solar wind interacting with the Earth's magnetosphere, and disturbances in the ionosphere. Other factors like geological processes and human-made magnetic fields can also contribute to magnetic drift.

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 are the two causes of electric and magnetic forces?
Electric forces are caused by the attraction or repulsion of electric charges, while magnetic forces are caused by the motion of electric charges.
What causes the magnetic force to occur in objects?
The magnetic force in objects is caused by the alignment of the magnetic moments of the atoms within the material. When these magnetic moments align in the same direction, they create a magnetic field and attract or repel other magnetic materials.
What causes Jupiter's magnetic field?
Jupiter's magnetic field is caused by the flow of electrically conducting material in its metallic hydrogen layer. As Jupiter rotates, this material generates a magnetic field. The combination of the planet's rotation and its metallic hydrogen layer results in its strong magnetic field.
What causes white stripes on teeth and nails?
lack of calcium in your body causes white stripes on teeth and nails.
