Web3) an explanation for the apparent "wandering" of the Earth's magnetic pole Know that the evidence that led to the acceptance of seafloor spreading was: 1) mapping of the world-encircling mid-ocean ridge 2) age of the oceanic crust increasing away from the mid-ocean ridge Know that the evidence that shows that the age of the oceanic crust increases with … WebMid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. Along these boundaries, earthquakes are common and magma (molten rock) rises … Lesson 2 - Mid-Ocean Ridges.

WebIn 1961, scientists began to theorize that mid-ocean ridges mark structurally weak zones where the ocean floor was being ripped in two lengthwise along the ridge crest. New 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. WebHow mid-oceanic ridges are formed?
