Geological processes have helped to create many iconic features on Earth. Processes, such as plate tectonics, are what shapes the face of the Earth. Here you can discover the power of geological processes.
Mountain Lake in Virginia is best known for its starring role in 'Dirty Dancing.' But today, it's nothing more than a muddy pit that's all but dried up ... and geologists think they may know why.
Gondwana was a humongous landmass that persisted for 300 million years before it began to break up, forming all the continents in the modern Southern Hemisphere.
The Earth is unique in the solar system because its surface is made of moving plates, which may enable the very existence of life.
Many scientists believe that humans influence Earth at a rate so massive that a change to the geologic time scale is in order.
Permafrost across the globe is rapidly melting. What could this mean for the future of the planet?
The U.S. is full of exceptional geological formations. But these five set the bar high as far as landmarks go.
You can see these rocky formations in the Badlands of Nebraska, and they're as awe-inspiring as they are eerie.
If fettuccine rock exists on Mars, it would suggest the existence of microbial life there.
Caves are full of incredible geological formations, including stalagmites and stalactites. But you've probably never seen anything like cave popcorn before.
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.
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.'
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.
How, in today's world, could a cave this massive go undetected for so long?
Will a town in southern Missouri be the epicenter of the next 'big one'?
The oceans on planet Earth cycle through daily tidal changes. But the ground beneath our feet experiences tides of its own, too.
The Sahara has expanded by about 10 percent in the past century, mostly due to natural causes, but not all. We can blame the rest on man-made climate change.
Petrified wood can be found all over the world, but how is it created?
Scientist have figured out why two historic avalanches happened on the same unlikely slopes within weeks of one another.
If geology has taught us anything about Earth's history, it's that nothing is permanent. And that goes for mountain ranges, all of which are constantly rising and falling.
Geologists agree that the world's landmasses were once all one supercontinent. Is it likely to happen again?
The beautiful scenery in Washington state hides a darker history. It was formed by a gigantic volcanic eruption that cooled the planet.
Scientists have found that snow and rain trigger earthquakes. Could their study help predict the Big One?
Antarctica's Blood Falls looks like a geological horror scene. For decades, scientists weren't sure why. Until now.
