Dangerous Earth

Highly interesting documentary series that reveals from A to Z how certain natural phenomena arise. For example, the first episode not only explains how an avalanche occurs, but also how it is that the snow becomes almost hard as concrete during an avalanche, with the result that someone who gets buried under the snow usually does not come out on their own. The answer is as surprising as it is logical when you think about it for a moment. Although this series cannot visually compete with a "Planet Earth II", it is nevertheless fascinating and educational enough for those who would like to know more about the natural phenomena that are discussed.
