Water 'Missing for Decades' Found 400 Miles Beneath US

But the water is neither liquid, ice, nor vapor: researchers

(Newser) - Four hundred miles beneath the United States, there appears to be enough water to fill all our oceans—almost three times.

Earth's Oldest Rocks: 4.4B-Year-Old Crystals

They're not much younger than the planet itself

(Newser) - When scientists claimed more than a decade ago that tiny crystals in Australia were 4.4 billion years old, they faced skepticism. The Earth itself, after all, is 4.5 billion years old, the Sydney Morning Herald notes. "Nothing in science goes without being questioned," geochemist John Valley...

Yellowstone Blasts Incredibly Old Helium

The gas has been building for hundreds of millions of years

(Newser) - Yellowstone National Park has long been known as a gassy place, and its reputation as such just got more firmly established. That helium emanates from the ground in the park is an established fact, Smithsonian Magazine explains, but when researchers dug into the makeup of that helium, what they found...

70M Years Old? No, Grand Canyon Mostly Just a Kid

Much of it is just 5M years old, geologists find

(Newser) - The Grand Canyon is nowhere near the grand old age of 70 million years that earlier studies claimed, according to new research. "The Colorado River found a path and carved the entire canyon 5 (million) to 6 million years ago," says a geologist who used data measuring the...

New Zealand's Tallest Mountain Has Shrunk

Ice collapse decades ago knocks almost 100 feet off Mount Cook

(Newser) - The highest point in New Zealand is about 100 feet shorter than we thought. A new measurement of Aoraki/Mount Cook puts its height at roughly 12,217.8 feet, down from an official listed height of 12,316.3 feet, Stuff.co.nz reports. That discrepancy likely isn't due...

Scientist: Massive Quakes Hidden in History

Huge seismic events missing from the records

(Newser) - The Earth might have a more turbulent past—and hence a more turbulent future—than we thought. In a presentation yesterday, Dr. Susan Hough of the US Geological Survey argued that hidden throughout history are a glut of giant earthquakes that either went unrecorded or have been underestimated. "Seismometers...

New Zealand Quakes Made Earth's Crust Weaker

Geologists find weakening for 3 miles around crust

(Newser) - How nasty were the deadly quakes that hit New Zealand one after another in 2010 and 2011? So bad that they appear to have seriously weakened the Earth's crust, scientists reveal in a new study. Geologists had previously believed that the strength of the Earth's crust was more...

Scientists Accidentally Discover Even Grander Canyon

In Greenland, but no one's ever seen it

(Newser) - Scientists have—totally by accident—come across a hidden canyon that dwarfs the Grand one, the BBC reports. The researchers were using radar to map out Greenland's bedrock when they stumbled upon the 2,625-foot deep feature, which, at 500 miles, is longer than the Grand Canyon's 277...

Latest Search for Alien Life Taking Place on Earth

NASA turns to geologists for help

(Newser) - NASA's latest partner in the search for alien life: a group of about 50 geologists who are hunting for evidence of ancient life here on Earth.

New Study Offers Proof: Asteroid Wiped Out Dinos

New study puts mass extinction within 32K years of meteor

(Newser) - Paleontologists and dinosaur nerds have long debated what killed off the "terrible lizards"— one meteor or many , volcanoes , or something else.

Study: Grand Canyon 70M Years Old, Not 6M

Which means dinosaurs might have roamed there, say researchers

(Newser) - Visit the Grand Canyon, and signs will inform you that scientists believe it is about 6 million years old, which, a new study suggests, is a mere 64 million years or so off. A group of "contrarian" geologists published a paper today arguing that the canyon is about 70...

Oldest Impact Crater Found in Greenland

Meteorite probably smashed down about 3B years ago
