The origin of the Earth and its evolution are closely related to the cosmic environment of our planet. The book tells about the formation of the Earth as a cosmic body and its structure, about the riches of the earth's interior. The reader will learn about the news of planetology, a science that studies the general problems of the development of planets. The space relations of the Earth, determining its development as one of the planets of the solar system, and such exciting problems of geology as the “drift of the continents” and the expansion of the Earth are considered. Written simply and fascinatingly, the book "You Earthlings!" is available to the widest range of readers. -Published--
