Three kilometers of ice can hide a lot, but not forever. Beneath East Antarctica, researchers have identified a ...

A mysterious geological structure that resembles a human hand with outstretched fingers has been revealed beneath East ...

Ancient rocks on the coast of Oman that were once driven deep down toward Earth's mantle may reveal new insights into subduction, an important tectonic process that fuels volcanoes and creates ...

The dance of the continents has been reshaping Earth for billions of years, creating the landscapes we walk on today. Scientists are unlocking secrets about how plate tectonics forged our modern world ...

Vast, quasi-circular features on Venus's surface may reveal that the planet has ongoing tectonics, according to new research based on data gathered more than 30 years ago by NASA's Magellan mission.

Mountain building, also known as orogenesis, is a geological process that involves the formation and uplift of large, elevated landforms, known as mountains. The term "orogenesis" comes from Greek ...

Earth's geographical surfaces have been formed over millions of years, and various current theories aim to explain their formation. The most popular theory, called the "plate tectonics theory," states ...

MIT geologists have found that a clay mineral on the seafloor, called smectite, has a surprisingly powerful ability to sequester carbon over millions of years. Under a microscope, a single grain of ...

Some 4.5 billion years ago, a Mars-sized object smashed into the nascent Earth, spinning off our moon. Now a team of scientists proposes this giant impact did even more: The collision left behind ...

Geoscientists have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas of Earth's crust long before it should be geologically altered by known plate-boundary ...

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 ...
