Tracing the Legacy of Pontus The Pontus plate was a key component of a much larger, interconnected system of tectonic plates that dominated the western Pacific region for over 150 million years.

Geographic (A) and tectonic (B) maps of the Philippine Sea Plate region. Present-day plate boundaries are red (modified from Bird, 2003), relevant former plate boundaries are gray.

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...

In a new study, a team of researchers suggests that 4 billion years ago, plate tectonics likely looked closer to what we experience today than previously thought. The team published its findings ...

The research provides chemical evidence that plate tectonics was most likely occurring more than 4.2 billion years ago when life is thought to have first formed on our planet.

Whereas Earth has plate tectonics, some other bodies — such as Mars, Mercury and Earth's moon — have what is called a stagnant lid.

Plate tectonics explains the movement and interaction of the Earth's upper layers. More accurately, the lithosphere, which is composed of the crust and upper layer of the mantle.

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-like plate tectonics may have shaped Venus billions of years ago A new study bolsters the theory that microbial life could have existed on our sister planet. Laura Baisas Oct 27, 2023 11:00 ...
