Is sea floor spreading divergent
WitrynaDivergent plate boundaries: ... Sea floor spreading: As basaltic lava erupts at linear fissures along mid oceanic ridges, it pushes a wedge between the continents in a process known as sea floor spreading. As the magma cools, tiny grains of the magnetic mineral magnetite align with Earth's magnetic field and are locked into place. ... WitrynaAbout.

Is sea floor spreading divergent
Did you know?
The depth of the seafloor (or the height of a location on a mid-ocean ridge above a base-level) is closely correlated with its age (age of the lithosphere where depth is measured). The age-depth relation can be modeled by the cooling of a lithosphere plate or mantle half-space in areas without significant subduction. In the mantle half-space model, the seabed height is determined by the oceanic lithosphere and … Witryna21 mar 2024 · Seafloor Spreading.

Witryna29 paź 2024 · Seafloor spreading is the geologic process that takes place when tectonic plates diverge, resulting in the creation of new ocean floors. Divergent plates contribute to seafloor spreading, as magma ... WitrynaSea-Floor Spreading Answer Key. This is a mid-ocean ridge. It is an underwater mountain range that forms when magma pushes up on the crust at a divergent boundary. Seafloor spreading is happening at B. Molten rock pushes up from the asthenosphere and pushes the plates apart at the mid-ocean ridge. This creates new …
