A bathymetric map of the Mid-Atlantic Ridge (shown in light blue in the middle of the Atlantic Ocean) The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
Mid-Atlantic Ridge, submarine ridge lying along the north-south axis of the Atlantic Ocean; it occupies the central part of the basin between a series of flat abyssal plains that continue to the margins of the continental coasts. Learn more about the Mid-Atlantic Ridge.
The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean, slowly spreading at a rate of 2 to 5 centimeters (0.8 to 2 inches) per year and forming a rift valley that is about the depth and width of the Grand Canyon.
29 Οκτ 2018 · The ridges are the divergent zones where oceanic plates are born, spreading apart from the central valley, or axial trough. This map shows the overall configuration of the ridges and their names. Click the image for a 900-pixel version.
Mid-Ocean Ridges. A brief exploration and history of the planet's underwater mountain ranges.
17 Απρ 2017 · The Mid-Atlantic Ridge (MAR) is known as a mid-ocean ridge, an underwater mountain system formed by plate tectonics. It is the result of a divergent plate boundary that runs from 87° N...
The Mid-Atlantic Ridge, which stretches for thousands of miles in the Atlantic Ocean, is the longest mountain chain on Earth. Understanding the geologic processes at the ridge, mapped here using satellite data, was crucial as scientists developed the theory of plate tectonics.
