[edit] Information

From the Big Bang to today, explore Earth's 4.5-billion-year history of unimaginable timescales, incredible life forms, radical climates, and mass extinctions. Spectacular on-location shooting, evidence from geologists in the field, and clear, dramatic graphics combine in Season Two of this stunning series from HISTORY to show how immensely powerful, and at times violent, forces of geology have formed our planet. This season, HOW THE EARTH WAS MADE goes back in history-- from 4.5 billion years ago to today-- peeling back layers of rock, filling up river canyons, parting the oceans, and levelling mountains and volcanoes to investigate the origins of some of the most well-known locations and geological phenomena in the world. 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. From a once seething, hellish mass of molten rock to the world that inhabits life today, take a rollercoaster ride through the entire history of Planet Earth. Its 4.5 billion year epic, a story of unimaginable timescales, earth-shattering forces, incredible life forms, radical climates and mass extinctions. Discover how the continents were formed, canyons were carved, and why the world's animals live where they do. The series examines some of the most well-known locations and geological phenomena in the world, including the Grand Canyon, Vesuvius, Sahara, the birth of the Earth, Yosemite, Death Valley, Everest, and the Pacific Ring of Fire. Using interviews with experts, geological evidence, and computer generated graphics, the series explains in an easy-to-understand way how those locations and geological phenomena have been shaped by the immensely powerful, and at times violent, forces of geology. Experience all 13 episodes of this landmark series for the first time on Blu-ray. Produced by Pioneer TV For HISTORY / A & E Television Networks

[edit] The Grand Canyon

The relatively tiny Colorado River had substantial help in carving out a chasm as wide and deep as the Grand Canyon. The Grand Canyon is nearly 300 miles long and over a mile deep. You could stack four Empire State buildings one on top of the other and they still wouldn't reach the lip of the Canyon. As vast tectonic plates clash and grind against one another a giant plateau has been pushed up over a mile in the air. The Colorado river, flowing from high in the Rockies and carrying a thick load of sediment, has carved an amazing canyon in the rising plateau. The story is so complex and the evidence so scarce that it took geologist decades to unravel the mysteries.

[edit] Vesuvius

Volcanologists look for patterns in the historical eruptions of Mount Vesuvius to determine when the worlds most dangerous volcano is likely to threaten the residents of Naples. Mt Vesuvius is the world's most dangerous volcano, and it threatens three million people. It was responsible for the most famous natural disaster of ancient history, the eruption that destroyed the Roman city of Pompeii. And its most recent blast was caught on film in 1944. Today Vesuvius is the most densely populated volcano in the world. Now recent scientific discoveries show that it is capable of an eruption larger than ever before thought possible and that hidden beneath Vesuvius there is a vast magma chamber of boiling hot rock, ready to come out.

[edit] Birth of the Earth

The Earth isn't an ordinary generic planet. The processes that created an Earth suitable for modern are unique and surprising. Four and a half billion years ago the Earth formed from dust in space to become a molten ball of rock orbiting the Sun. This episode travels back in time to investigate how the fledgling planet survived a cataclysmic cosmic collision with another world, how molten rock solidified to land, how our oceans filled with water and how life arrived on Earth. Geologists study the oldest rocks on Earth and meteorites from outer space to solve the greatest geological mystery of all--the Birth of the Earth.

[edit] Sahara

Scientists present evidence that the Sahara Desert periodically transitions from desert to a lush green environment and back. They also present theories about why this happens. Africa's Sahara Desert is the size of the United States, making it the largest desert in the world. It's also the hottest place on the planet. But now an astonishing series of geological discoveries has revealed this searing wasteland hides a dramatically different past. Scientists have unearthed the fossils of whales, freshwater shells and even ancient human settlements. All clues to a story that would alter the course of human evolution and culminate in biggest climate change event of the last 10,000 years.

[edit] Yosemite

The dispute between John Muir and Josiah Whitney over how the Yosemite Valley formed is settled with a 200 million year long story more complex then either imagined. The Sierra Nevada, North America's highest mountain range, contains one of the most awe-inspiring geological features on the planet: Yosemite Valley. Walled by sheer 3,000-foot granite cliffs and made from one of the toughest rocks on earth, it is home to the mighty El Capitan and iconic Half Dome. Yet how this extraordinary valley formed has been the subject of controversy for over 100 years. Was it carved by gigantic glaciers or a cataclysmic rifting of the Earth?

[edit] The Rockies

Geologists believe the Rocky Mountains recently rose from an inland sea to twice their current size and becoming a new inland sea may be their not to distant fate. From Alaska to New Mexico, the Rockies are one of the great mountain belts of the world--caused by tectonic forces of the Pacific Plate pushing against the North American continent. They have formed as the earth's continental crust has been shortened under pressure--by around 1 inch a year. What's more, they are still rising and they are still young in geologic terms: when the dinosaurs roamed the Earth they had not even started to form.

[edit] The Ring of Fire

The geological mechanism that causes the ring of volcanoes around the pacific ocean is studied and explained. The single longest linear feature on Earth--the "Ring of Fire" circles almost the entire Pacific. It is a ring of active volcanoes from White Island just north of New Zealand, through the South China seas, Japan, Kamchatka, the Aleutians, the Cascades and down through the Andes. Almost 25,000 miles long, it is one of the most awesome sights on Earth.

[edit] Everest

The convergence of processes that resulted in the extreme height of Mt. Everest and the other Himalayan mountains is explained in conjunction with the supporting geological evidence. It is the tallest and biggest mountain on earth, as far removed from sea level as it's possible to be--and yet its sedimentary layers contain fossils that were once creatures that lived on the ocean seabed. The Himalayas formed when India smashed into Asia--propelled by plate tectonics. Everest is still rising but its height is limited--extreme erosion counteracts and limits the amount of uplift.

[edit] Death Valley

The history of Death Valley's transformation from an inland sea to a towering mountain range then to a fresh water lake and finally the salt bed we see today is revealed. It is not only a place of natural splendour but a geologic treasure trove as well. Hidden in the sediments of the rocks in its walls is evidence of the coldest time on our planet--ironic in one of the hottest places on Earth. Death Valley is literally being pulled apart and the floor is collapsing and lower than sea level. Here and across much of Nevada is the Basin and Range province--a series of ridges of mountain ranges that are being pulled apart and the basins between them getting wider and flat as they fill with eroded sediment.

[edit] Mt. St. Helen's

The Mount Saint Helens 1980 eruption introduces geologists to a variety of volcanic phenomenon never observed before. Yet it presages a similar eruption thousands of miles away and just a few years later in Montserrat. Over 20 years ago, Mt. St Helens--thought to be dormant--shocked America when it exploded. It is an acidic volcano--the magma beneath is full of volatiles making it highly explosive. A new plug has formed in its throat and is rising. When it blows it will be like uncorking a champagne bottle, releasing pressure below and allowing dissolved gases to escape and explode. The question is...when will it blow again?

[edit] Earth's Deadliest Eruption

The causes of the million year volcanic eruption in the Siberian Traps and the resulting effects that lead to the largest mass extinction in earth's history are recounted. In the remote wastes of Siberia buried under snow are the remains of one of the greatest catastrophes that the Earth has endured. 250 million years ago, huge volumes of lava spewed out onto the surface--so much that it would have buried the whole of Texas under one mile of lava. At first the temperature dipped but then the greenhouse gases that escaped from the depressurized lava caused a massive global warming. It wreaked havoc and 95 percent of the species on Earth became extinct. Yet life hung on and in time this disaster paved the way for the next great phase of life on earth--the age of the dinosaurs.

[edit] America's Ice Age

Instead of looking at a geological feature and the convergence of mechanisms that created it, this program uses a different format; looking at one mechanism, glaciers, and the diverse effects they cause. Why do we have ice ages and when is the next one due? Chart the progress of different ice ages through the history of our planet, from Snowball Earth hundreds of millions of years ago to the recent ice ages. As the Earth circles the sun, its orbit changes slightly and so does it angle of rotation. When the right wobble in our rotation combines with the right orbit, the Earth is, and will again be, plunged into an ice age--but maybe not for a few thousand years.

[edit] America's Gold

The history of discovery of gold deposits in California and Nevada and the diverse geological processes are described. Gold dates from the time of the supernova explosion that gave birth to the building blocks of our solar system. When it was created, the Earth included a tiny percentage of gold atoms, and over the aeons geologic processes have concentrated it into various nooks and crannies around the globe. The best of it is in the ancient Precambrian rocks in South Africa, where the deepest mines in the world extract it. In other regions of the world, gold can be gathered from younger sedimentary rocks that have been eroded off older Precambrian rocks. The American gold rush was this type of deposit. Now in Nevada, sedimentary rocks are leached on a truly vast scale to extract the gold.
