WebThis 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 … WebSeafloor spreading happens at the bottom of an ocean as tectonic plates move apart. The seafloor moves and carries continents with it. At ridges in the middle of oceans, new oceanic crust is created.

Faster rates tend to cause more volcanic activity, which releases... WebSeafloor spreading is the process by which the ocean floor gradually widens. This widening occurs as the new oceanic crust is created at mid-ocean ridges and spreads outwards. The process is driven by convection within the Earth’s mantle. Molten rock (magma) rises through the cover and solidifies on the ocean floor to form a new crust.

WebSep 27, 2024 · Seafloor spreading occurs at divergent plate boundaries.
