Mid-ocean ridge cross-section (cut-away view) A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. It typically has a depth of about 2,600 meters (8,500 ft) and rises about 2,000 meters (6,600 ft) above the deepest portion of an ocean basin.

The mid-ocean ridge system is the most extensive chain of mountains on Earth, stretching nearly 65,000 kilometers (40,390 miles) and with more than 90 percent of the mountain range lying underwater, in the deep ocean.

The mid-ocean ridge is the world's longest continuous mountain range, stretching over 65,000 kilometers (40,000 miles) across the globe. Located primarily along divergent tectonic plate boundaries, these underwater ridges play a crucial role in shaping Earth's geological landscape through the process of seafloor spreading and volcanic activity.

What Is The Mid-Ocean Ridge? The mid-ocean ridge system is the most extensive chain of mountains on earth, but more than 90% of this mountain range lies in the deep ocean. The mid-ocean ridge wraps around the globe for more than 65,000 km like the seam of a baseball.

2024年4月20日 · Mid-ocean ridges are not just underwater mountains; they are the dynamic engines of our planet. As divergent plate boundaries , they create new oceanic crust, drive plate tectonics, influence ocean chemistry, support unique ecosystems, and provide invaluable insights into Earth’s history.

2024年6月16日 · The longest mountain range on Earth is called the mid-ocean ridge. Spanning 40,389 miles around the globe, it's truly a global landmark. About 90 percent of the mid-ocean ridge system is under the ocean.

2020年11月10日 · The mid-ocean ridge is a continuous range of undersea volcanic mountains that encircles the globe almost entirely underwater. It is a central feature of seafloor terrain that is more varied and more spectacular than almost anything found on dry land, and includes a collection of volcanic ridges, rifts, fault zones, and other geologic features.

A mid-ocean ridge is a zone where new seafloor is constantly created due to the welling of molten rock from beneath the earth’s surface. To understand why mid-ocean ridges form, it’s helpful to understand a few basics of plate tectonics .

2024年5月30日 · The Mid-Ocean Ridge is an extensive, continuous mountain range located under the ocean, stretching across the globe, generally through the center point of all major oceans. It is technically the longest mountain range in the world.

The global mid-ocean ridge system is the largest single volcanic feature on the Earth, encircling it like the seams of a baseball. Here the Earth’s crust is spreading, creating new ocean floor and literally renewing the surface of our planet.
