There's a rare material called Darwin Glass that Tasmanian Aboriginals have prized for centuries. And while it took Western researchers a while to figure out what it was and where it came from, once they got their heads around it, they...

We know that fossils are fragile, and volcanoes are destructive. So you wouldn't think that volcanoes are really any help when preserving fossils... but you'd be wrong! From the Laetoli Footprints to the Blue Lake Rhino, here are five...

Most of Earth’s land is currently in the northern hemisphere because we happen to exist in a time where uneven heating in the mantle has pushed many continental plates northward.<br/>

In astronomy we talk about billions of years like it’s no big deal. But how can we be sure about timescales so far beyond the capacity for human intuition? Our discovery of what we now call deep time is very recent - as recent as our...

Rocks are more than just rocks, they're the key to Earth's history!

There are a lot of weird places here on Earth, but here are a few of our favorite strange spots!

From towering mountains to pebbles along a river, the Earth is made of a huge variety of rocks. In today's episode, we're going to follow the rock cycle of a piece of granite in the Himalayan mountains, and as you'll see, every rock has...

Maybe you've seen pictures of glowing blue lava flows and dismissed them as Photoshop trickery. Healthy skepticism is good, but there really is a volcano in Indonesia where a unique fluke of chemistry creates an eerie blue glow.

In the midst of a volcanic eruption, lightning can streak across the ash and smoke above it, but what do we think causes volcanic lightning?

We have new insights into the bizarre nature of lava planets, and the icy moon Europa may yet reveal some of her salty secrets.

Thanks to some amazing scientific insights, we know a lot about the interior of our planet - even though we’ve never even made it through the crust.

We have a garbage problem. Wouldn't it make sense to throw that trash into the nearest volcano?

Rocks are more than just rocks, they're the key to Earth's history!

In February of 1942, Mexican farmer Dionisio Pulido thought he heard thunder coming from his cornfield. However, the sound wasn't coming from the sky. The source was a large, smoking crack emitting gas and ejecting rocks, and would come...

This video describes how volcanoes are often formed along tectonic plate boundaries, or over hotspots. The Ring of Fire is also illustrated.

This video explores the basic features of volcanoes.

Explore how researchers Ingo Sonder and Andrew Harp simulate volcanic eruptions to study magma-water interactions.<br/>
