Crystal cave in Joplin Missouri is a Geode of immense size lying some 70 feet below the surface. Covered on all sides with giant crystals it was first opened in 1908 when mining in the area dewatered the cave. It became a tourist attraction as well as a cool summer center of entertainment with a dance floor. When mining stopped in the area the cave was reclaimed by the water and to this day it remains water filled. It is still hoped that one day the cave can be restored and once again its remarkable crystals, some two feet in length, can be enjoyed once again.

Scientists have long attempted to understand Earth’s past, and in service to that effort, they have divided the world’s history into eons, eras, periods, epochs, and ages. For example, the current eon is called the Phanerozoic Eon, which means “visible life”. This is the eon in which multicellular life has evolved and thrived. Before this, life was microscopic (single cells).

Rocks and mountains have withstood aeons of life on our planet - gradually eroding, dissolving, recycling, shifting, solidifying, and weathering. We might spend a little less time on earth, but humans are also weathering: evolving and changing as we're transformed by the shifting climates of our lives and experiences. So, what might these ancient natural forms have to teach us about resilience and change?

Long dismissed as a relic of a bygone era, coal is back -- with a vengence. Coal is one of the nation's biggest and most influential industries -- Big Coal provides more than half the electricity consumed by Americans today -- and its dominance is growing, driven by rising oil prices and calls for energy independence. Is coal the solution to America's energy problems?

The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species-these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news.

This Is Planet Earth is dedicated to the wonders of planet Earth, the most amazing place in the known universe. The ancient Greeks called it Gaia, the Romans Terra. We know it simply as Earth, the planet we call home. And what a planet it is. Formed around 4.6 billion years ago from the debris of the big bang and long-dead stars, at first it was nothing special, but somehow it evolved to become the most amazing place in the known universe.

Sempre intenti a "riveder le stelle", per citare il Sommo Poeta, ma ci siamo mai interessati veramente a quanto accade invece sotto i nostri piedi? La risposta è sì, ovviamente, ed è proprio quello che fanno i geologi: studiano la Terra! Eppure, in chi non la conosce, la geologia è una scienza che evoca spesso, e ingiustamente, un sapore stantio. Un luogo comune che il nostro geologo preferito, Andrea Moccia, autore del progetto divulgativo "Geopop", si è proposto di sfatare in questo libro.

From the secret fossils of London to the three-billion-year-old rocks of the Scottish Highlands, and from state-of-the-art Californian laboratories to one of the world's most dangerous volcanic complexes hidden beneath the green hills of western Naples, set out on an adventure to those parts of the world where the Earth's life-story is written into the landscape. Helen Gordon turns a novelist's eye on the extraordinary scientists who are piecing together this planetary drama.

Humans depend on soil for 95 percent of global food production, yet let it erode at unsustainable rates. In the United States, China, and India, vast tracts of farmland will be barren of topsoil within this century. The combination of intensifying erosion caused by climate change and the increasing food needs of a growing world population is creating a desperate need for solutions to this crisis.

Travelling a thousand miles and across three billion years, Christopher Somerville (walking correspondent of The Times and author of Coast, The January Man and Ships of Heaven) sets out to interrogate the land beneath our feet, and how it has affected every aspect of human history from farming to house construction, the Industrial Revolution to the current climate crisis. In his thousand-mile journey, Somerville follows the story of Britain's unique geology, travelling from the three-billion-year-old rocks of the Isle of Lewis, to the furthest corner of Essex.
