The layers of air of the earth is called the atmosphere. At different altitudes, it varies in pressure and temperature. Therefore, the atmosphere is divided into five main layers depending on altitude. Author: ZDF/TerraX/Julia Knüppel/Ellen Haas/Malik Alpoguz/Maximilian Mohr Translation and dubbi
In the atmosphere, at an altitude of about 20 to 30 kilometers, the ozone layer protects us from carcinogenic UV rays. But on earth, on the ground, ozone is a problem. Here, the colorless and toxic gas harms people and the environment. More about ozone: http://www.umweltbundesamt.de/ozon Transla

Plants can grow not only on soil-rich ground, but also on rocks. Due to their porosity, the rock layers lying beneath the thin upper layer of soil can store water. Author: ZDF/Terra X/Florian Roth/Thomas Kuschke/Jochen Rall/Maximilian Mohr Translation and dubbing: alugha Click here to watch more
An analog compass responds to the Earth's magnetic field. A digital smartphone compass, however, works without a magnetic needle. The job of the magnetic needle is taken over by a sensor made of three layers. Authors: ZDF/3sat/nano/Autorenkombinat/Josephine Blume, Holger Barthel, Ingo Schwarz /Alex
How are fossils actually formed? And why are they formed in some places and not in others? Author: ZDF/Terra X/Spiegel TV/Jens Nicolai/Oliver Roetz/Hauke Ketelsen/Richard Sako Translation and dubbing: alugha Click here to see more videos: https://alugha.com/TerraX
How do tree rings form? And what do they tell us about the past? Every year, a tree forms a new layer of growth, so the more rings a tree has, the older it is. The seasons are the reason for this. Authors: ZDF/TerraX/Leon Altfeld/Julia Bruch/Maximilian Heß Translation and dubbing: alugha Click he
Learn the basics about the renewable feedstocks principle of green chemistry, as a part of environmental chemistry. Many plastic products are derived from crude oil, which is a non-renewable resource. It takes millions of years for dead carbon-based living organisms to be compressed by layers an
Learn how the analysis of rock layers and ocean sediments supports the theory that rapid climate change may have jump-started human evolution two million years ago in this video from NOVA: "Becoming Human". CREDITS: https://www.pbslearningmedia.org/credits/clim10.sci.ess.watcyc.evoclimate/ LICENSE
Learn the basics about carbon neutral and biofuels, as a part of environmental chemistry. Coal, oil, natural gas, shale gas and gas from fracking are fossil fuels formed hundreds of millions of years ago from living things that got trapped by layers of sediment before they had time to decompose. H
Learn the basics about what designer polymers are, some examples of them, and how chemical properties are used to perform a particular function. Polymers have been around for a long time. Some of the commonly named examples are found in clothes, things like nylon, polyesters and acrylic. Others ar
Learn how scientists used the fossils of one-celled aquatic organisms, called diatoms, to understand ancient climate conditions in eastern Africa, in this video from NOVA: Becoming Human. White layers of a rock formation consist of deep-water diatoms and darker layers consist of shallow-water diatom
