Web4. Pakiexplain po ang lahat ng pumapatungkol sa seafloor spreading sa tagalog. Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics. WebParts of the East Pacific Rise have oblique spreading, that is seafloor spreading that is not orthogonal to the nearest ridge segment. Along the East Pacific Rise the hydrothermal vents called black smokers were first …
WebMost seafloor spreading centers lie at depths exceeding 2,000 meters (1.2, miles) and, as a consequence, approximately three-quarters of all volcanic activity on Earth occurs as deep, underwater eruptions. The effects of these deep eruptions cannot be seen from the surface of the ocean.

Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed. ism cable
