The Giant's Causeway is a rock formation that is so otherworldly that it seems like it was made by supernatural beings. But these incredible hexagonal columns of rock aren't the result of giant masons. They formed through a quirk of...

While the eruptions of the volcanoes along the Mid-Atlantic Ridge usually don't trouble us, their birth was once responsible for ripping a supercontinent apart and creating the Atlantic Ocean that we know today.

Mount Teide is one of the world’s largest active volcanoes, and there may be a way to use the basalt rock inside it to save humanity. Obviously, destroying an ancient volcano would cause catastrophic and unpredictable ecological fallout....

Earth didn't always have the land beneath your feet, but what might have caused it to form is a bit of a mystery.

Over 600 million years ago, sheets of ice coated our planet on both land and sea. How did this happen? And most importantly for us, why did the planet eventually thaw again? The evidence for Snowball Earth is written on every continent...

In the early 20th century, Alfred Wegener's theory of Continental Drift laid the foundation for our modern theory of plate tectonics. And today we know something even more exciting: Pangea was only the latest in a long lineage of...

Astronomers took advantage of a lunar eclipse to study Earth as if it were an exoplanet, and Mars's Insight lander used seismic data to reveal for the first time boundaries between different layers of Mars.

You might think of plate tectonics as destructive since it's the ultimate force behind earthquakes, tsunamis, and volcanic eruptions. But the slow movement of our planet's surface does a lot more than shake things up now and then. Some...

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?

Even though there are no volcanoes on the Olympic Peninsula, you can find lots of volcanic rocks on the beaches. This bizarre circumstance might have to do with how the ancient island transformed Washington state.

If we ever want to live, sleep, eat, and breathe on Mars, we are going to need some the best tech humans can dream up - and as a bonus that tech might actually help tackle challenges right here on Earth!

Climate change is happening we all need to get serious about limiting our carbon dioxide emissions! At the same time, scientists are looking for plan B because we might need it.

Artificial Intelligence has helped astronomers discover 2 new planets in systems that we'd already looked at, and new theories about how Mars lost some of its water have surfaced.

The surface layer of a rocky planet or other astronomical body, usually chemically distinct from the mantle beneath it.

Dr. Forrester explains the three types of volcanoes.

This video describes the causes of volcanic eruptions and some of the different ways eruptions can occur.

This video explores five fun facts about Igneous Rocks.

Now that we know how igneous rocks form, what are the types of igneous rocks? This depends on precisely where they form, and we can call them either intrusive or extrusive. These can also be called either plutonic or volcanic. What do...
