What are the different types of plate tectonic boundaries?

What are Plate Boundaries? Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at...

K-T Boundary “Cretaceous-Tertiary Boundary”

What is K-T Boundary? The Cretaceous–Tertiary extinction event, now called the Cretaceous–Palaeogene extinction event. It may be called the K/T extinction event or K/Pg event...

K-Pg Boundary “Cretaceous–Paleogene Boundary”

What is the K-Pg Boundary? The Cretaceous–Paleogene (K–Pg) extinction event, was a sudden mass extinction of some three-quarters of the plant and animal species on...

The solid Earth breathes

The solid Earth breathes as volcanoes "exhale" gases like carbon dioxide (CO2) -- which are essential in regulating global climate -- while carbon ultimately...

New light into the recent evolution of the African rift valley

Continental rift valleys are huge fractures on the surface of our planet that progressively break continental plates with the eventual development of new oceans....

Tectonics in the tropics trigger Earth’s ice ages

Over the last 540 million years, the Earth has weathered three major ice ages -- periods during which global temperatures plummeted, producing extensive ice...

Tibetan plateau rose later than we thought

The Tibetan Plateau today is on average 4,500 meters above sea level. It is the biggest mountain-building zone on Earth. Most analyses to date...

Fate of the subducted oceanic crust revealed by laboratory experiments

Professor Tetsuo Irifune of the Geodynamics Research Center (GRC) of Ehime University heads a research group investigating the Earth's interior by means of experiments...

Earth’s continental nurseries discovered beneath mountains

In his free time last summer, Rice University geoscientist Ming Tang made a habit of comparing the niobium content in various rocks in a...

Scientists reconstruct ancient lost plates under Andes mountains

The Andes Mountains are the longest continuous mountain range in the world, stretching about 7,000 kilometers, or 4,300 miles, along the western coast of...

Climate, life and the movement of continents: New connections

A new study by The University of Texas at Austin has demonstrated a possible link between life on Earth and the movement of continents....

Enhanced views of Earth tectonics

Scientists from Germany's Kiel University and British Antarctic Survey (BAS) have used data from the European Space Agency (ESA), Gravity field and steady-state Ocean...

A wrench in Earth’s engine: Stagnant slabs

Researchers at CU Boulder report that they may have solved a geophysical mystery, pinning down the likely cause of a phenomenon that resembles a...

Plate Tectonics May Have Been Active on Earth Since the Very...

A new study suggests that plate tectonics—a scientific theory that divides the earth into large chunks of crust that move slowly over hot viscous...

Geologists reveal ancient connection between England and France

The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research. Scientists have for centuries...

Upper Cretaceous trench deposits of the Neo-Tethyan subduction zone

The Jiachala Formation, which was fed largely from the Gangdese arc, has long been considered to comprise syn-collisional foreland-basin deposits based on the reported...

Study finds deep subterranean connection between two Japan volcanoes

Scientists have confirmed for the first time that radical changes of one volcano in southern Japan was the direct result of an erupting volcano...

Scientists propose solution to ‘Gaia puzzle’

Scientists may have solved a long-standing puzzle over why conditions on Earth have remained stable enough for life to evolve over billions of years....

Earth could have supported continental crust, life earlier than thought

The early Earth might have been habitable much earlier than thought, according to new research from a group led by University of Chicago scientists. Counting...

New insight into Earth’s crust, mantle and outer core interactions

A new study by the University of Liverpool, in collaboration with the Universities of Lancaster and Oslo, sheds light on a longstanding question that...
