Web5 aug. 2024 · The two geological processes that help explain the shrinking of the Pacific Ocean are seafloor spreading and subduction. Seafloor spreading is when tectonic plates split from each other, creating a new oceanic crust. This process gradually pushes tectonic plates apart and occurs at underwater mountain ranges called mid-ocean ridges. Web1 apr. 2010 · As the plates move, new sea floor can be created. The plates form three different kinds of boundaries: convergent, divergent, and transform. Convergent …

WebAlong these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate … WebNew magma from deep within the Earth rises easily through these weak zones and eventually erupts along the crest of the ridges to create new oceanic crust. This process, at first denominated the "conveyer belt hypothesis" and later called seafloor spreading, operating over many millions of years continues to form new ocean floor all across the …

Webapart and new crust is created by magma pushing up from the mantle.
