In many rivers, only a small amount of streamflow remains for nature after water is diverted for hydropower production. In light of climate change and biodiversity loss, this is having increasingly serious consequences. Researchers from WSL,...
Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada. The Nuvvuagittuq Greenstone Belt has long been known for its ancient rocks—plains of streaked gray stone on the eastern shore...

Venus had Earth-like plate tectonics billions of years ago, study suggests

Venus, a scorching wasteland of a planet according to scientists, may have once had tectonic plate movements similar to those believed to have occurred...

Plate tectonics 4 billion years ago may have helped initiate life on Earth

The Earth's oldest surface layer forming continents, termed its crust, is approximately 4 billion years old and is comprised of 25–50km-thick volcanic rocks known...

Plate tectonics in the Pacific and Atlantic during the Cretaceous period shaped the Caribbean region

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

Plate tectonics in the twenty-first century

The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying...

Study shows tectonics to be main driver of hillslope ‘connectivity’

Chances are good that most people reading this are situated on a hillslope, as hillslopes cover some 90% of the Earth's landmass. Hillslopes are critical...

Grain size of rocks in Earth’s mantle affects tectonics

The planet is shaped by forces deep within its interior. These push the plates of the Earth's crust against each other, causing mountains and...

New maps of global geological provinces and tectonic plates

New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a...

How plate tectonics, mountains and deep-sea sediments have maintained Earth’s ‘Goldilocks’ climate

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...

Earliest geochemical evidence of plate tectonics found in 3.8-billion-year-old crystal

A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to...

Unearthing evidence for the origins of plate tectonics

Minerals trapped inside tiny crystals that have survived the grinding of the continents over billions of years may help to reveal the origins of...
