Planetary scientists have produced the first global map of small mare ridges on the Moon, adding new evidence that the lunar surface has been reshaped in geologically recent times by tectonic forces ...

In subduction zones, the sites of the world's largest earthquakes, tectonic activity may generate a "pump" that transports long-buried subseafloor microbes back toward the seafloor, according to ...

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...

Lake Turkana in northern Kenya is often called the cradle of humankind. Home to some of the earliest hominids, its fossil-rich basin has helped scientists piece together the story of human evolution.

Much of the brittle, upper crust of Venus is broken into fragments that jostle and move – and the slow churning of Venus’ mantle beneath the surface might be responsible. My colleagues and I arrived ...
