Far beneath the Atlantic Ocean, about 1,000 kilometers off Portugal’s coast, lies a colossal underwater canyon system that ...

New research reveals the source of this carbon – and the driving forces behind it – are far more complex than previously ...

In deep Earth, rocks take up and release water all the time, and the effects can be wide reaching. Dehydration can cause rocks to crack and trigger earthquakes, and over geologic timescales, this ...

With steep walls and deep valleys, the Grand Canyon in the western United States or the massive gorges that saw through the margins of the Tibetan Plateau are some of the most awesome and spectacular ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...

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 crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...

Tiny zircon crystals are revealing that Earth’s earliest history may have included surprisingly complex tectonic activity.

For hundreds of millions of years, Earth’s climate has warmed and cooled with natural fluctuations in the level of carbon dioxide (CO₂) in the atmosphere. Over the past century, humans have pushed CO₂ ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. A new study, using a combination of old models, new geophysical ...

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 ...
