This video uses a cake analogy to describe Earth's structure. It compares the Earth's crust to cake batter, the mantle to a mixed ingredient layer, and the core to the sweet, hot center of the cake—highlighting the different types of...

Earth’s outer shell is made of two materials whose different densities and thicknesses give rise to two distinct “levels” on the planet’s surface.

Researchers from the Australian National University have found evidence of an additional layer inside the Earth’s inner core

For the last hundred and fifty years or so, geologists have been trying to wrap their heads around the mystery: in some places, the geologic record just seems to jump by over billion years. And last week, a paper was published that may...

When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...

This video explains the concept of geologic time and how geologists determine the age of Earth and its rock layers. It introduces the idea of relative time and absolute time, and highlights the law of superposition. A Journey Through...

We just learned about all the layers of the Earth, but how did we accumulate this information? How do we know the composition of these layers and the depths at which they occur? The answer is seismology! Let's learn about the different...

The forces of sun, wind and water have changed the face of earth just as much as tectonics. Weathering and erosion are driven by gravity, flattening the landscape. They create soil. Deposition starts the process of forming sedimentary rock.

Now that we've learned about the layers of the ocean, let's focus on the floor. How did oceanographers learn about the composition of the ocean floor? What is sediment? How do different types of sediment get to the ocean and what...

For years, geologists have been searching for an explanation for two strange blobs of Earth's mantle that are denser than the rest. It turns out, they may not be original parts of Earth at all.

It's Earth Science time!!!! In this field, natural philosophers were asking questions like, what’s up with fossils? Are they the remains of extinct organisms? Or are they so-called “sports of nature”—rocks that just happen to look like...

Before taking a deep dive into the geology of the ocean's layers, let's review the basics of ocean life. What are the different sections of the ocean? What types of creatures live in each region?

We are approaching a whole new era! . . .or at least a new epoch. Michael Aranda explains how humans are leaving their mark on the Geologic Time Scale.

Seventeenth-century Danish geologist Nicolas Steno earned his chops at a young age, studying cadavers and drawing anatomic connections between species. Steno made outsized contributions to the field of geology, influencing Charles Lyell,...

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

Epidote might just look like a pretty little crystal, but it has a secret. thanks to the high-pressure circumstances where it forms, we can use it to help us uncover the origins of life on our planet, and maybe even find signs of life on...

You might have heard that Earth is due for a complete flip of its magnetic field. And while our planet does have a history of this behavior, predictions of when it might happen are too complex to estimate a date for.

In this video Paul Andersen explains in more detail the history of the Earth. He shows how the history of the Earth is written in the rocks that are built up over time. Fossils allow us to compare different rock layers relative to one...

In November 1986, Australian miners climbed Lunatic Hill and bored 20 meters into the Earth. They were rewarded with a fist-sized, record breaking gemstone, which they named the Hailey's Comet opal. Thanks to a characteristic called...

Or why we live on an onion made of magma

Our understanding of the world has to start somewhere! And while early ideas like the Hollow Earth Theory are mostly wrong and sound silly to us now, that doesn’t mean they weren’t important.
