Earth Science covers all facets of how the earth works, from from volcanoes to the world's oceans.
If fettuccine rock exists on Mars, it would suggest the existence of microbial life there.
Water surrounds us, falling from the sky and pouring from faucets, and yet many of us never ask where it comes from. The answer stretches way back — before tides and thunderclouds to the big bang.
To honor their prehistoric pasts, most U.S. states have designated official state fossils, ranging from trilobites to dinosaurs. Take our quiz to learn more!
Caves are full of incredible geological formations, including stalagmites and stalactites. But you've probably never seen anything like cave popcorn before.
"Will draw dinosaurs for food" is what they like to think they do. But it's actually way more complicated.
The spring, or vernal, equinox traditionally marks the first day of spring — but climate scientists use a different date altogether. Find out more about this and other facts about the spring equniox.
Scientists set up two stations to capture this strange seismic activity.
The decades-old geyser was created by accident when a geothermal company tried to drill a well. Now the strange geyser is open to tourists for the first time ever.
Massive gypsum crystals were discovered beneath Mexico's Sierra de Naica Mountain in very inhospitable environs — to humans anyway.
Sealab was a U.S. Navy program that allowed undersea divers to go deeper and stay underwater longer. So why did it disappear?
The Ancient Earth visualization map shows the movement of the planet's tectonic plates in a really cool way.
Many scientists believe that humans influence Earth at a rate so massive that a change to the geologic time scale is in order.
Sastrugi are gorgeous snow formations found in the polar north, but they're also no fun to travel over.
These ancient wonders aren't static sculptures; they vibrate and shift throughout the day, creating a variety of sounds as they stretch their aging, eroding 'bones.'
The pigment ultramarine was as expensive as gold in medieval Europe; so how did it end up in the teeth of a nun buried at a monastery in rural Germany?
What makes these spongy, waterlogged areas of decaying plant matter so perfect at preservation? In a word: science.
Prior to the mid-1990s, the magnetic north pole traveled at speeds of around 9 miles per year. Now, it's 34 miles annually. What accounts for the acceleration?
Researchers hypothesize that missing rocks from the geologic record, known as the Great Unconformity, were sheared away by glaciers at a time when most — or all — of the world's surface was coated with ice.
Lakes seem like serene places to escape and enjoy peace and quiet. So you'd probably be surprised to learn that a lake can actually explode without warning. It's happened, with deadly consequences.
How, in today's world, could a cave this massive go undetected for so long?
Stratospheric Aerosol Injection (SAI) is a controversial possibility in the effort to slow the rate of climate change.
Archaeologists recently unearthed dozens of mummified cats from a 2,500-year-old Egyptian tomb. So what were they doing there in the first place?
A bubbling mud pool is moving toward the San Andreas Fault, but scientists don't see evidence of an impending earthquake.
The super-cool phenomenon of tidal bores happens in only a few places on the globe, and it takes a very specific set of conditions to occur.
The oceans' levels change daily across the globe. We know them as tidal changes. But what causes this constant shift in sea level and why is it more dramatic is some places than others?
