A video entitled "Layers of History" which discusses how Earth's geographic features were formed, with a focus on the study of rock layers through absolute and relative dating.

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.

In the history of our species, we still don’t know exactly how and when early humans migrated across the world, but some ancient footprints might be helping us figure it out.

In some places, the rocks below the Great Unconformity are about 1.2 billion years older than those above it. This missing chapter in Earth’s history might be linked to a fracturing supercontinent, out-of-control glaciers, and maybe the...

About 1.8–0.8 billion ago, the Earth went through a period known as the Boring Billion, where not a lot changed in terms of geology, evolution, or even the number of hours in a day. Some scientists call it “the dullest period in Earth’s...

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

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

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...

Squeaks built a pretend time machine, and he and Mister Brown use their imaginations to travel back in time to learn all about the very first living thing!

Cave diver Jill Heinerth explores the hidden underground waterways coursing through our planet. Working with biologists, climatologists and archaeologists, Heinerth unravels the mysteries of the life-forms that inhabit some of the...

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...

Researchers estimate ancient temperatures using data from climate proxy records, i.e., indirect methods to measure temperature through natural archives, such as coral skeletons, tree rings, glacial ice cores, and so on. For example, the...

The video “The History of Life” gives a brief overview of the major time spans in Earth’s history, focusing specifically on the formation of life and how that life changed over time.

A video entitled “Relative Age of Fossils” describes the relative age of fossils.

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...

While excavating the Hohle Fels cave in southwestern Germany in 2008, scientists discovered a bone flute that turned out to be one of the oldest music instruments in the world. In this episode we take a closer look at the flute itself...

Learn the basics about the changes to our atmosphere, as a part of environmental chemistry.



The Earth’s early atmosphere had no oxygen. By examining rocks laid down over earth history we can piece together the...

This is the first in a series called A Journey Through Geologic Time. This series takes students on a journey through geologic time starting with the formation of Earth. The concept of geologic time is discussed, and highlights of the...

By looking at the layers beneath our feet, geologists have been able to identify and describe crucial episodes in life's history. These key events frame the chapters in the story of life on earth and the system we use to bind all these...

In the 1980s, the world faced a huge problem: there was a rapidly expanding hole in the ozone layer. If it continued to grow, rates of skin cancer could skyrocket, photosynthesis would be impaired, agricultural production would plummet,...

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.
