The WORST episodes of How the Earth Was Made

Every episode of How the Earth Was Made ever, ranked from worst to best by thousands of votes from fans of the show. The worst episodes of How the Earth Was Made!

There's a lot of information in How the Earth Was Made, but perhaps the most interesting relates to time. Quite often, the numbers are so staggering that scientists refer to it as "deep time," an appropriate term when one grapples with the notion that our planet is 4.5 billion years old, or that the oceans were formed by rainfall that lasted literally millions of years, or that 700 million years ago, Earth was completely covered by ice that was a mile thick, with surface temperatures reaching minus 40 degrees Fahrenheit. On the other end of the scale are numbers that seem surprisingly small: for instance, it wasn't until 220 years ago that the accepted church doctrine regarding the planet's age (no more than 6000 years, according to the Bible) was seriously challenged and that the key to its past was found in rocks, not scripture, while the discovery that dinosaurs once ruled the Earth came considerably later than that. Using a combination of computer graphics and animation, various drawings and diagrams, photos, location footage, and expert commentary, this fascinating, 94-minute History Channel production takes us from the very beginning, when the planet was formed by meteors colliding in space, through numerous major events (including the appearance of water, granite, and oxygen) and mind-boggling catastrophes (such as mass extinctions caused by volcanic eruptions or the enormous meteor that wiped out 75% of all living things, including the dinosaurs, some 65 million years ago), right up to the present; there's even a glimpse into the future, when Earth will likely end up as barren and lifeless as Mars (no need to hit the panic button yet, though--a few billion more years will pass before that happens). Bonus features include additional scenes and a documentary entitled "Inside the Volcano." --Sam Graham

Season 1 - Episode 2 - Aired 2/17/2009

The Marianas Trench is the deepest place on earth, deeper than Mt. Everest is high. The trench is where the ocean floor disappears into the center of the earth. The pressures at this depth are 17 times greater than what it takes to crush a nuclear submarine. Only two men have ever been down the Trench, fewer than have set foot on the moon. Follow the daring missions into the abyss and explore the extraordinary geology that has created this deep scar along the ocean floor

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.

It is the largest and most fearsome volcanic island on the planet. We'll scour the island for clues, to address the mystery of what powerful forces are ripping Iceland apart and lighting its fiery volcanoes. Here, lava rips huge tears in the ground and new islands are born from the waves. Yet despite the active volcanoes, Iceland historically has been covered in and carved by ice. Fire and ice collide, locked in a titanic battle, as glaciers explode and cataclysmic floods decimate the landscape. But Iceland's volcanoes have had ramifications far beyond the shores of Iceland, causing climatic chaos and devastation across the planet; a fate which may one day happen again.

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.

It is one of the most man-made spaces on the planet, but everything in New York from the height of the skyscrapers to the way the subway was constructed to the position of the harbor is governed by the extraordinary forces that ultimately shaped this city. You can tell the geology of Manhattan at a glance by looking at the skyline. The skyscrapers of Midtown and Downtown are built on hard granite; the low-rise buildings in between are built on a soft, gravelly soil left over from the Ice Age. Learn how New Jersey and North Africa were neighbors 250 million years ago, how the rocks New York are built on are the remains of mountains that 450 million years ago were as tall as the Himalayas, and how Long Island is covered in rubble that remained as ice sheets retreated 10,000 years ago.
