How does our planet work? Why do trees grow at the foot of the mountains and glaciers lie on the tops? Why do waves happen and how does the wind appear? Why doesn’t the water in the rivers run out, and the seas don’t overflow? What kind of Sun is under our feet? To find answers to these and many other questions, Chevostik and Uncle Kuzya set off on a journey again - this time on a magical flying swimmer. The heroes will fly around our beautiful planet, climb to the tops of mountains and descend into the depths of the sea, look closely at oceans, lakes and rivers, continents and islands, volcanoes and geysers. During the trip, Uncle Kuzya will talk about the most important natural phenomena and explain the reasons for their occurrence. The book is intended for children of primary school age.
