Are the continents moving? How did lunar craters form? What is the climate of the ice island of Greenland? The wonderful German scientist Alfred Wegener was looking for an answer to these and many other questions. He was a geophysicist, an astronomer, and a meteorologist - he was attracted by everything unknown. He expressed interesting theories and bold hypotheses. Many of his discoveries are now the domain of science; some hypotheses are rejected, and there are those that still cause heated debate. Wegener is known not only as an armchair scientist, but also as a polar traveler - an explorer of Greenland. This book is the first attempt to tell about the life of Alfred Wegener, a life full of tireless scientific research and dangerous exciting travels.
