What is Earth Science?

A quick look at the field of Earth Science, including the three main areas of study including astronomy, meteorology, and geology.

Earth Science: Crash Course History of Science #20

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 living things but don’t /mean/ anything? And most importantly, how old is… everything?

The History of Earth - How Our Planet Formed - Full Documentary HD

In the very beginning of earth's history, this planet was a giant, red hot, roiling, boiling sea of molten rock - a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth began to cool, forming a thin crust on its surface. As the cooling continued, water vapor began to escape and condense in the earth's early atmosphere. Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas.

It is theorized that the true age of the earth is about 4.6 billion years old, formed at about the same time as the rest of our solar system. The oldest rocks geologists have been able to find are 3.9 billion years old. Using radiometric dating methods to determine the age of rocks means scientists have to rely on when the rock was initially formed (as in - when its internal minerals first cooled). In the infancy of our home planet the entire earth was molten rock - a magma ocean.

Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth. Due to the forces of plate tectonics, our planet is also a very dynamic one; new mountains forming, old ones wearing down, volcanoes melting and reshaping new crust. The continual changing and reshaping of the earth's surface that involves the melting down and reconstructing of old rock has pretty much eliminated most of the original rocks that came with earth when it was newly formed. So the age is a theoretical age.

When Did Life on Earth Begin?

Scientists are still trying to unravel one of the greatest mysteries of earth: When did life first appear and how did it happen? It is estimated that the first life forms on earth were primitive, one-celled creatures that appeared about 3 billion years ago. That's pretty much all there was for about the next two billion years. Then suddenly those single celled organisms began to evolve into multicellular organisms. Then an unprecedented profusion of life in incredibly complex forms began to fill the oceans. Some crawled from the seas and took residence on land, perhaps to escape predators in the ocean. A cascading chain of new and increasingly differentiated forms of life appeared all over the planet, only to be virtually annihilated by an unexplained mass extinction. It would be the first of several mass extinctions in Earth's history.

Scientists have been looking increasingly to space to explain these mass extinctions that have been happening almost like clockwork since the beginning of living time. Perhaps we've been getting periodically belted by more space rocks (ie. asteroids), or the collision of neutron stars happening too close for comfort? Each time a mass extinction occurred, life found a way to come back from the brink. Life has tenaciously clung to this small blue planet for the last three billion years. Scientists are finding new cues as to how life first began on earth in some really interesting places - the deep ocean.

The Earth System

This video describes the four main components of the Earth system (atmosphere, biosphere, geosphere, hydrosphere), how matter is exchanged between the components, and how a change in some aspect of one part of the system will result in changes in other system components. We describe the Earth system in terms of reservoirs and flux between them and discuss how the movement of carbon occurs between system components.

A Brief History of Geologic Time

Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here:

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 chapters together is the Geologic Time Scale.

Thanks to Studio 252mya for their illustrations. You can find more of their work here:

Layers of the Earth for Kids | #aumsum

Layers of Earth.
Many years ago, when Earth was formed, it was very hot.
Rains and thunderstorms cooled the outer portion and different life forms started originating on the earth.
The outer cool layer on which we live is called Crust.
Earth's crust is covered with landforms, air and water.
After crust, the next layer is Mantle.
Mantle is the layer below the crust. Mantle is very hot. Mantle consists of rocks in molten form.
The Core is located just below the Mantle.
Core is divided into two parts, outer core and inner core.
The outer core is in liquid state.
The inner core is in solid state.

Convex Earth - The Documentary - The Flat Earth Scientific Proof

Terra convexa is an independent research of Dákila Researches and Centro Tecnológico Zigurats ctzbrasil.com.br originally published in and convexearth.org

After seven years of research on earth format, scientific experiments carried out by Brazilian researchers at Dakila Research and the Zigurats Technological Center in partnership with professionals from various areas of Brazil and other countries, such as the United States, Russia, Chile, the Netherlands, Spain , have shown that the Earth is not spherical. The evidence is being presented in the feature film Terra Convexa: The Documentary, available in three languages: Portuguese, English and Spanish and published on the websites terraconvexa.com.br and convexearth.org Seven scientific experiments were carried out, including the geodesic, which consisted in measuring the distances between the bases and tops of a building in Torres (RS) and another in Natal (RN), with a distance of 3,050 km between them. reference to sea level. The measurements were the same. If the Earth were spherical, the measure of the distance between the bases should be smaller than the measurement between the upper parts of the buildings because they would be following the curvature of the Earth, explains Urandir de Oliveira, founder of Dakila Research. Engineers from the National Institute of Colonization and Agrarian Reform (INCRA) participated in the action. A long-range laser was used to measure the flatness and leveling of the waters at the Três Marias Dam (MG); in Lagoa dos Patos (RS), on Lake Titicaca, Peru; and in the seas of Ilhabela (SP) and in the Strait of Gibraltar. The tests performed up to 35 km did not identify any curvature. Experiments with refracting and reflecting telescopes have proved that boats do not disappear on the horizon, but we lost the ability to observe them due to an optical phenomenon. This phenomenon was studied by the researchers, who formulated a new physical theory, which explains physically and mathematically how this works. Experiments with plumbing (verticalization) and level (horizontalization) have proved that gravity does not exist, because the physical behavior of water is to seek its original form, that is, flatness. According to Urandir, what holds us firm to the ground is the MDPL (magnetism, density, pressure and light). Through images obtained through several atmospheric probes launched by the researchers, as well as of incursions made, including in Antarctica, with the collaboration of the Armed Forces of Brazil, as well as other analyzes of materials found in glaciers of Siberia and the shores of the Arctic Glacial Ocean , such as pollen, dust and other fragments, a new continent, known as the Greater North, was discovered, separated by a large mass of ice. The trajectory of the stars, including the Sun and the Moon, is totally different from what science says. The new information enabled the correct positioning of the continents. The complete research information, with regard to equipments, coordinates, images, all techniques, research content, technical reports, scientific papers, mathematical calculations and proposed theories will be available soon on the websites .br and A book with the complete compilation of the research will be released soon.

Every other Wednesday we present a new video, so join us to see the truth laid bare...

There is a place on Earth that we have never seen. It is a place of unimaginable heat and pressure, where no life could survive. Yet without it, we would perish for it holds the key to our precarious existence on this planet.

2000 miles below the Earth's surface, there is a vast ocean of molten iron. The spinning outer core of the Earth generates a protective magnetic shield around the planet, defending life from lethal space radiation. But now there is startling data that it could be about to stop defending us. Naked Science is taking you on a journey to the centre of the Earth.
