When the continental crust stretches beyond its limits, tension cracks begin to appear on the Earth's surface. Magma rises and squeezes through the widening cracks, sometimes to erupt and form volcanoes. The rising magma,

How does magnetic striping occur? – Sage-Advices

WebMagnetic striping occurs when the sea floor spreads and magma from the mantle rises through the Earth’s crust. The “Oceanic Crust” is formed by the magma that turns into a new crust. What does magnetic striping reveal to us? It becomes permanently magnetized in the direction of the Earth’s magnetic field as it cools. WebThis process, called subduction, occurs at the oceanic trenches (figure 6). The entire region is known as a subduction zone. Subduction zones have a lot of intense earthquakes and volcanic eruptions. The subducting plate causes melting in the mantle. The magma rises and erupts, creating volcanoes. chipa fairlawn https://cfandtg.com

What causes the magnetic striping in the mid-ocean ridges?

WebIn the 20th century, the magnetic survey was conducted in the Mid-ocean ridge in order to investigate evidence of sea-floor spreading. By using the magnetometer, the magnetic polarity will be shown through a timescale that contains the normal and a reverse polarity. The minerals contained in the rocks are oriented opposite to the magnetic field. WebJul 19, 2024 · What mechanism has caused magnetic striping of the ocean floor? At spreading centres, this crust is separated into parallel bands of rock by successive waves of emergent magma. When Earth’s geomagnetic field undergoes a reversal, the change in polarity is recorded in the magma, which contributes to the alternating pattern of … WebAs the magma cools, it is pushed away from the flanks of the ridges. This spreading creates a successively younger ocean floor, and the flow of material is thought to bring about the migration, or drifting apart, of the continents. grant county ky circuit clerk
