Some features, like canyons and seamounts, might look familiar, while others, such as hydrothermal vents and methane seeps, are unique to the deep. This graphic shows several ocean floor features on a scale from 0-35,000 feet below sea level.

WebMid-ocean ridges are created by the upwelling of basaltic lava and lateral rifting of ocean crust (Figure 6.12 ). They form a rift valley system that encircles the Earth along a total length of over 75,000 km ( Figure 6.11 ). The mid-ocean ridges are the earth’s largest volcanic system, accounting for >75% of all volcanic activity on the planet. WebThe Mid-Ocean Ridge [70 k] In 1947, seismologists on the U.S. research ship Atlantis found that the sediment layer on the floor of the Atlantic was much thinner than originally thought. Scientists had previously believed that the oceans have existed for at least 4 billion years, so therefore the sediment layer should have been very thick.

Web1 jan. 2024 · Comparing the ages of the oceanic crust near a mid-ocean ridge shows that the crust is youngest right at the spreading center, and gets progressively older as you move away from the divergent boundary in either direction, aging approximately 1 million years for every 20-40 km from the ridge.
