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...

Learn about the earth's Tectonic Plates with the Layers of the Earth /Earths Lithosphere

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.

This video is answering the question of where are what are the different layers of The Earth.

We only interact with the very surface of the Earth, called the crust. So what else is down there? What is the composition of the Earth? How many layers are there, and how do they differ? What is the mantle, and how does it convect? What...

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...

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...

This video provides an educational tour through the different layers of a tropical rainforest, explaining the unique environments and diverse wildlife found in each layer. It highlights the emergent layer, canopy, understory, and forest...

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?



Composition of Oceanic Crust...

Discover how Earth formed over 4.6 billion years ago, from a cloud of dust and gas to a planet with continents. Learn about the process of continental drift and how it shaped the seven continents we know today.

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...

The Global-scale Observations of the Limb and Disk, or GOLD, instrument launches aboard a commercial communications satellite in January 2018 to inspect the dynamic intermingling of space and Earth’s uppermost atmosphere. Together,...

This video explores the layers of the Earth, from the crust to the inner core, comparing it to the layers of a sandwich. They discuss the composition and characteristics of each layer, highlighting the unique properties of the mantle,...

Atmosphere Set: 1. This clip examines the chemical composition and the layers of the atmosphere.

What are the layers of the planet made up of? What are Aurorae? Why are there so many volcanoes on the moon IO? <br/>
Jupiter, The King of Planets, Part 2

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.

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!

In this stunning slideshow, celebrated nature photographer Frans Lanting presents The LIFE Project, a poetic collection of photographs that tell the story of our planet, from its eruptive beginnings to its present diversity. Soundtrack...

This video explains the importance of the epidermis in plants, which acts as a protective layer against environmental factors such as injury, water loss, and insect attacks. The epidermis also contains stomata, which allow for gas...

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.

A hydrogen atom is traveling high within the outermost layer of Earth's atmosphere. This particular atom first entered the exosphere millions of years ago, but today it overcomes Earth's gravitational pull and escapes, joining the...

One of the toughest materials known to science is made not by humans, but by nature... and it's inside of oysters.
