New research introduces a paleoenvironmental model in which tidal dynamics influenced the earliest development of agriculture and sociopolitical complexity...
Planetary scientists have discovered more than 15,000 km of ancient riverbeds in Noachis Terra, a region in Mars’ southern highlands. This discovery...
Observations of large valley networks on today’s Mars suggest formation by flowing water. However, most climate models cannot sustain temperatures above...
Earth’s coastlines are fascinating places where liquids mix and materials are shaped into distinct landforms like river deltas. Similar active coastlines...
Mount Everest, also known as Chomolungma in Tibetan or Sagarmāthā in Nepali, is about 15 to 50 m taller than it would otherwise be because of uplift...
Archaeologists in Egypt have identified segments of a 64-km-long extinct branch of the river Nile, which they name the Ahramat Branch, running at the foothills...
Accurate assessment of global river flows and stores is critical for informing water management practices, but current estimates of global river flows...
Geoscientists from Durham University and elsewhere have discovered a landscape that appears to have been formed by rivers at least 14 million years ago...
Ancient river deposits exist across Mars and can be identified in satellite data by erosional landforms called fluvial ridges. Fluvial ridges take the...
Paleontologists have found several fossilized bones of plesiosaurs — traditionally thought to be sea creatures — in the Kem Kem beds, a 100-million-year-old...
Early Mars had rivers, but the cause of the transition from a wet planet to dry remains unknown. Past Martian climate can be probed using the distribution...
Planetary scientists have analyzed images taken by the Mastcam-Z camera and the Remote Micro-Imager of the SuperCam instrument on NASA’s Perseverance...
Using data from the Context Camera aboard NASA’s Mars Reconnaissance Orbiter, planetary researchers have generated an 8-trillion-pixel global map of...
A possible subterranean river flows from the deep interior of Greenland to Petermann Fjord, suggests a paper published in The Cryosphere.
A possible subglacial...
The remarkably high abundance of the teeth of the giant dinosaur Spinosaurus aegyptiacus, compared to the dental remains of terrestrial dinosaurs and some...
Planetary researchers from the University of Texas at Austin and NASA’s Marshall Space Flight Center have used dry paleolakes and riverbeds to determine...
While the present-day Martian surface is generally dry and cold, its sedimentary rocks contain compelling evidence for the former presence of liquid water....
A species of carnivorous dinosaur called Spinosaurus aegyptiacus used tail-propelled swimming locomotion to hunt for prey in rivers, according to a new...
The Nile is a 4,130-mile (6,650 km) long river in northeastern Africa. It has been suggested that the river in its present path is at least 6 million...
