The natural water cycle is powered from solar energy. Its thermal radiation evaporates water from oceans, lakes and rivers into water vapour. As precipitation, the water enters lakes, rivers and groundwater and eventually flows into the sea. Author: 3sat/nano, mirror TV, Christine Voges, R. Engelk
Europe could fit twice into North America. This cultural region includes Canada and the USA. The natural landscape is defined by five major regions. From the tropics to polar regions, all climate zones are represented. Authors: ZDF/Terra X/Susanne Hillmann/Iris Gesang/Spiegel TV/Maximilian Mohr Tr
In nature, all organisms compete with each other for resources in order to survive. Competition between members of the same species is what makes organisms evolve. This theory of competition and ‘survival of the fittest’ is called Natural Selection, and was originally proposed by Charles Darwin i
The way we grow and develop in the womb is controlled by our DNA. Small sections of DNA, called genes, carry the code telling the body how to build itself. Usually this works fine, but sometimes those genes carry mistakes in their code. These mistakes, known as mutations, may have no effect, they ma
The study of finches led to the development of one of the most important scientific theories of all time. In December 1831 a naturalist called Charles Darwin boarded the HMS Beagle, bound on a surveying voyage of South America. Whilst the ship and crew carried out coastline surveys, Darwin was fre

When ice crystals at high altitudes in cirrus clouds refract sunlight, a halo appears. But a classic halo is only visible when the light exits at an angle of 22 degrees. Autor: ZDF/Terra Xpress/Autorenkombinat/Birthe Heer/Sebastian Kerz/Tobias Schönke/Maximilian Heß Translation and dubbing: alugha
The noble gas configuration is a particularly stable electron configuration. The driving force for many chemical phenomena is this state. It should be remembered again that the nucleus is not altered during chemical reactions. Original: "Wolfgang Dukorn" Original: German. All translations in this
