Similar-looking ridges on Mars have diverse origins
Thin, blade-like walls, some as tall as a 16-story building, dominate a previously undocumented network of intersecting ridges on Mars, found in images from NASA's Mars Reconnaissance Orbiter.

Scientists analyzing a volcanic eruption at a mid-ocean ridge under the Pacific have come up with a somewhat contrarian explanation for what initiated it. Many scientists say undersea volcanism is triggered mainly by upwelling ...

The earthquake distribution on ultraslow mid-ocean ridges differs fundamentally from other spreading zones. Water circulating at a depth of up to 15 kilometres leads to the formation of rock that resembles soft soap. This ...

The texture of the ocean floor is determined by the enormous stretching and cracking that takes place at the mid-ocean ridge, where tectonic plates are pulling apart and magma is rising to form new sea floor. On either side ...
