- Der Grand Canyon
F1Der Grand CanyonDer Grand Canyon ist rund 450 Kilometer lang und stellenweise bis zu 1,8 Kilometer tief – eine Tiefe, die der mehr als vierfachen Höhe des Empire State Buildings entspricht. Durch tektonische Bewegungen und Überlagerung der Platten wurde eine von ihnen auf über 1,6 Kilometer über den Meeresspiegel empor gehoben. Genau an dieser Stelle kam es durch das Abtragen von Sedimentschichten durch den Colorado River auch zur Bildung der riesigen Felsschlucht. - Der Vesuv
F2Der VesuvMt 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. - Die Sahara
F4Die SaharaAfrica'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. - Der Yosemite National Park
F5Der Yosemite National ParkThe 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? - Die Rocky Mountains
F6Die Rocky MountainsFrom 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. - Der Pazifische Feuerring
F7Der Pazifische FeuerringThe 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. - Mount Everest
F8Mount EverestIt 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. - Mega-Eruption
F11Mega-EruptionA look back 250 million years ago when a massive volcanic eruption, (in what is now Siberia), spewed lava one mile thick over an area the size of Texas and caused intense climatic change that killed 95% of the life on the planet; paving the way for the next dominant species – the dinosaurs.
