Земля — это МАШИНА. И вот что работает внутри неё

Have you ever wondered what lies right beneath your feet? We build cities, lay roads, and live our lives, completely unaware that just a few kilometers below begins a world hotter than the surface of the Sun. A world of molten metal, monstrous pressure, and forces capable of moving entire continents. In this video, we'll take an incredible journey deep into our planet — from the city sidewalk to the very center of the Earth, to a depth of more than six thousand kilometers. We'll pass through the Earth's crust, thin as the skin of an apple. We'll peer into the underground rivers of Florida, hidden beneath golf courses. We'll learn why the deepest borehole in the world stopped at twelve kilometers, even though scientists drilled it for twenty-two years. We'll descend into the scorching mantle, where volcanoes and diamonds are born, where the temperature reaches two thousand degrees. We'll pass through the ocean of liquid metal of the outer core, which generates the magnetic field — an invisible shield protecting all living things from the deadly solar wind. And finally, we'll reach the solid metallic ball the size of the Moon at the very heart of the planet, where the pressure is four million times higher than at the surface. You'll learn why earthquakes, mountains, and volcanoes are merely a side effect of the workings of a colossal underground machine. Why sea turtles find their way home across an entire ocean. And what will happen to the continents in two hundred fifty million years. Get ready to look at our planet in a completely new way. Make yourself comfortable — the journey to the center of the Earth begins right now.
