Houchin and his colleagues studied dozens of zircon crystals from the Jack Hills in Western Australia. These are the oldest ...

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 ...

The interiors of rocky planets and moons tend to be pretty hot compared with their surfaces. This heat, which can be caused by a number of sources — such as tidal stretching and compression, the ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge ...

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 ...

A new study introduces a novel way for tectonic plates — massive sheets of rock that jostle for position in the Earth’s crust and upper mantle — to bend and sink. It’s a bit of planetary Pilates that ...

Movements and pressure occurring between three major tectonic plates in the subduction zone near Sabah have been identified ...

A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published in the open access journal AGU ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes, and ...
