WebThe Earth's Magnetic Field — The Earth's magnetic field is thought to arise from the movement of liquid iron in the outer core as the planet rotates. The field behaves as if a permanent magnet were located near the center of the Earth, inclined about 11 degrees from the geographic axis of rotation (Fig. 4).

"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.

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 causes magnetic anomalies? Titanomagnetite minerals in basalt and gabbros carry the source of these anomalies primarily through permanent magnetization. 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.

WebAt spreading centres, this crust is separated into parallel bands of rock by successive waves of emergent magma.
