The Appalachian Mountains are some of the oldest geological features on earth. And they also hold fossils that tell us about some of the very earliest life forms that we'll ever manage to see in the fossil record. So how did these...

SciShow News explains the forces at work behind the earthquake in Nepal, introduces you to a new species of dinosaur, and reveals a discovery in Antarctica.

Lots of geological forces need to come together for continents to form, but they all require one ingredient: water.

Looking at a map, you would never know that North America once almost ripped itself in half. But 1.1 billion years ago, it tried to - and had it succeeded, there would now be an ocean where Lake Superior is!

The myth of the Minotaur tells the story of an enraged beast forever wandering the corridors of a damp labyrinth, filled with a rage so intense that its deafening roar shakes the earth. But is this story just fiction, or an attempt of...

You need it, you love it, you probably live on it: it's land! But have you ever thought about where land even comes from?

Looking at a map, you would never know that North America once almost ripped itself in half. But 1.1 billion years ago, it tried to - and had it succeeded, there would now be an ocean where Lake Superior is!

Today we're going to tell the story of a quiet revolution in the 1960s that shifted our entire understanding of how the Earth works. We currently believe that the Earth's broken outer shell rises from the mantle and folds back in - kind...

If all of Antarctica’s ice melted, our coastlines would be drastically altered. Fortunately, that’s not going to happen anytime soon, but new evidence suggests that West Antarctica - which holds around 5 METERS of sea level rise - is...

A massive earthquake is expected to hit the Pacific Northwest at some point, due to the Cascadia Subduction Zone. This 9.2 magnitude quake could trigger a huge tsunami and destroy major cities like Seattle, collapsing buildings, roads,...

Subduction zone earthquakes are the largest and most destructive on earth. In the Pacific northwest lurks the Cascadia Subduction Zone, which has been dormant for centuries and is overdue for its next “big one.” So, In this episode,...

Learn about how earthquakes happen, and Divergent, Convergent And Transform boundaries with this fun educational song about tectonic plate boundaries. This video is and adults. Brought to you by KLT. Don't forget to sing along.

“Plate Tectonics” will look at the movement of tectonic plates, and how they have shaped our world.

“Ocean Floor Features” will examine the different types of features in the ocean, primarily on the ocean floor.

Now that we've briefly gone over the history of the Earth, it's time to look at some different geologic structures that span all those eons. This will require gaining an understanding of rock deformation. We need to discuss the terms...

Seismic activity around the Mariana Trench have revealed the earth around it could be taking in at least 4.3 times more water than previously thought
