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...

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.

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,...

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...

There is no natural hole to the center of the planet Earth, so seeing what is in the center is difficult. Scientists haven’t ever drilled deeper than 2,000 feet into the Earth’s crust. Seismographs are used to measure earthquakes, which...

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...

What exactly will happen when the sun dies?

- Help support more content like this! Our home plane Earth is the third planet from the sun. We have one moon, liquid water, and life! Earth is the only planet...

Unpack the geological processes that cause earthquakes, from the structure of the Earth's layers to the movement of tectonic plates. Understand the types of plate boundaries and the phenomena of seismic waves and fault lines, which...

Every so often we hear in the news about a volcano eruption, somewhere far away. But what exactly are they and why should we care? Join MightyOwl in this exploration of volcanoes and how they alter the shape of the Earth.

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...

The land surface of the Earth accounts for 1% of its total volume. Travel from the core to Earth's surface, examining the layers that make up our planet. Earth Science - Geology - Learning Points. The Earth is made up of four layers. The...

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...

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...

By the end of this learning object, the student will be able to: Recognize the structure of the ozone layer and the formation of the ozone gas.4437

A Perlan glider uses air rising over the southern Andes to reach record heights and allow scientists to study the ozone layer. ONE STRANGE ROCK AIRS MONDAYS 10/9c. ➡ Subscribehttp://bit.ly/NatGeoSubscribe' target='_blank'...

Recently, a group of scientists have declared that the start of the Anthropocene, the time of outsize human influence on Earth, to be Crawford Lake in Canada. But how can a time be a place? We'll explain, and maybe grab some maple...

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...

Scientists have known the outside of the sun spins slower than the inside for a while, but they didn't know why until recently.

Students will learn about the different layers of the atmosphere. The changes in the atmosphere are explained using examples of contemporary environmental conditions brought about by human behavior. The oxygen cycle and the carbon cycle...

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

When a theory makes a prediction that disagrees with an experimental test, sometimes it means we should throw the theory away. But what if that theory has otherwise produced the most successful predictions in all of physics? Then, that...

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.
