How are mid-ocean ridges created
WebHess theorized that the ocean floor is at most only a few hundred million years old, significantly younger than the continents. This is how long it takes for molten rock to ooze up from volcanically active mid-ocean ridges, spread sideways to create new seafloor, and disappear back into the Earth’s deep interior at the ocean trenches. 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.

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 … WebMid-Ocean Ridges Some places along the ridge are like canyons, diving up to 4,000 m deep (close to 4,400 yards). Other places are like mountains, climbing up to 2,500 m tall (over 8,000 feet).
