History Channel - How the Earth Was Made Series 1 - BluRay (2009) Part 2 The Deepest Place on Earth

From a seething ocean of radioactive, molten rock to a refuge for life as we know it, Earth has undergone a staggering series of cataclysmic transformations in its long and epic history. Assailed relentlessly for millions of years by meteorites, our once toxic and hostile planet has been covered in water and in ice, and seen the rise and sundering of continents, the creation of an atmosphere, and, ultimately, the beginning of life. HOW THE EARTH WAS MADE plots the twisting course of Earth's amazing journey. Using groundbreaking special effects and traveling to remote locations where our planet still bears the scars of its violent history, this compelling documentary tells a story of unimaginable timescales, world-shattering forces, radical climates, and mass extinctions. HISTORY journeys back in time to show the creation of Earth s land masses, the birth of the first complex creatures, and devastating extinctions–before speculating on the future when all life becomes extinct. Spectacular on-location footage, evidence from geologists in the field, and clear, dramatic graphics combine in this stunning 13-part series from HISTORY to show how immensely powerful, and at times violent, forces of geology have formed our planet. Investigate with HISTORY the origins of some of the most well-known locations and geological phenomena in the world. From the Great Lakes to Iceland, the San Andreas Fault to Krakatoa, HOW THE EARTH WAS MADE travels the globe to reveal the physical processes that have shaped our planet. With rocks as their clues and volcanoes, ice sheets, and colliding continents as their suspects, scientists launch a forensic investigation that will help viewers visualize how the earth has evolved and formed over millions of years. Locations covered in “How the Earth Was Made” include Hawaii, a remote island chain brought to being by the movement of super heated magma deep within the earth, to the Marianas Trench, a spot in the sea deeper than Mount Everest is high, where the ocean floor disappears into the centre of the earth. Experience all 13 episodes of this landmark series for the first time on Blu-ray.

Part 2 The Deepest Place on Earth

Lying seven miles below the surface of the sea, the Marianas Trench is the deepest place on Earth. Oceanic discoveries in the 1950s and 60s led to the development of a powerful new theory of earth science called plate tectonics. The theory states that the earth's crust consists of about a dozen large, rigid sections called plates. The motions and relative positions of these plates help to determine where earthquakes, volcanoes, and mountain ranges occur. The discovery of the Marianas Trench and other features of the ocean floor were important in the development of the theory. Now investigate the mystery of this strange underwater abyss, where a world of fiery mountains, bizarre marine mud volcanoes, and devastating tsunamis reveal how the deepest scar on Earth's crust was created.
