Three types of global glaciations of the Earth

The Earth has been at the mercy of global glaciations several times during its development. An analysis of the modern structure of the Earth, its geological, geographical and other forms shows that these glaciations radically differed in genesis, duration, nature and scale of influence on the development of the Earth as a planet and life on it. Global glaciations were initiated by factors of both planetary and cosmic scale. This article provides information about the three main types of global glaciations on planet Earth.
