It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...

Plate tectonics may have gotten a pretty early start in Earth’s history. Most estimates put the onset of when the large plates that make up the planet’s outer crust began shifting at around 3 billion ...

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.

Vast amounts of sediment eroded from Earth’s continents were necessary to lubricate the wheel of plate tectonics, scientists propose. The idea offers a new angle on long-standing riddles about the ...

(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 ...

The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

What makes a mountain grow, and what keeps it from reaching unimaginable heights? Mount Everest, rising 8,848.86 metres above sea level, offers a case study in the interplay of tectonics, erosion, ...

A previously unknown tectonic plate — one that has been swallowed up by the Earth — has been discovered in the Philippine Sea, according to a recent study. Using images constructed from earthquake ...

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 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 ...
