THE WOODLANDS, Texas — Venus’ crust is broken up into chunks that shuffle, jostle and rotate on a global scale, researchers reported in two talks March 20 at the Lunar and Planetary Science Conference ...

(Inside Science) — Shifting, slipping and colliding tectonic plates played an essential role in the emergence and evolution of life on Earth. Such tectonic activity generated volcanoes that spewed ...

Life loves rivers. Here on Earth, large drainage basins cover nearly half of the land surface. On Mars, they cover only about 5% of the ancient terrain. Because of this small footprint, it would be ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...

A new study suggests that plate tectonics -- a scientific theory that divides the earth into large chunks of crust that move slowly over hot viscous mantle rock -- could have been active from the ...

With tectonic plates bumping and grinding against each other, Earth is a pretty active planet. But when did this activity begin? A new study from Yale University claims to have found evidence that ...

SIOUX CITY (KTIV) - Gather your supplies! In this episode we will use everyday materials to learn about tectonic plates and fault lines. A subduction fault is when two plates have different densities.

Far beneath the South Pacific, a continent the size of India has finally stepped out of the cartographic shadows. After centuries of speculation and decades of targeted surveys, scientists have now ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

Inside most of the Earth, olivine is a hot mineral whose creepy behavior drives plate tectonics. In the upper mantle — the top of the planetary layer between the crust and core — olivine's unusual ...

The Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the deep-seated ...

When plate tectonics emerged in the 1960s it became a unifying theory, “the first global theory ever to be generally accepted in the entire history of earth science,” writes Harvard University science ...
