The King's Trough Complex is a several-hundred-kilometer-long, canyon-like system of trenches on the North Atlantic seafloor.

Be sure to watch GMSA@9 on Wednesdays, when KSAT Meteorologist Sarah Spivey demonstrates and explains the science behind it.

Some great ideas shake up the world. For centuries, the outermost layer of Earth was thought to be static, rigid, locked in place. But the theory of plate tectonics has rocked this picture of the ...

From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new modeling study published in Geochemistry, Geophysics, Geosystems, R. Dietmar ...

What appears to be three tectonic plates in a map may act like five pieces that move underground. Northern California ...

We often affiliate plate tectonics with earthquakes, as we are all taught in school that the shifting of plates leads to big shakes. But plate tectonics serve a far more important job to the planet ...

It has been thought that plate tectonics were a significant factor in the shaping of our planet and the evolution of life. Mars and Venus don't experience such movements of crustal plates, but then ...

Three huge tectonic plates meet at the Mendocino triple junction off the coast of northern California, and a new study ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that ...

A new paper has revealed that tectonic activity on this planet—a unique feature in the solar system—could have been spurred by a stream of asteroid impacts. Previously, computer models have shown that ...

Memorizing seven continents feels settled, like learning the alphabet. A new study argues the ground rules are less tidy.
