The early history of Earth covers such vast stretches of time that years, centuries, and even millennia become virtually meaningless. Instead, paleontologists and scientists who study geochronology divide time into periods and eras. What humans commonly refer to as the “Ice Age” is actually a series of fluctuating climate events that have occurred throughout the planet’s history. These ongoing historical phenomena are difficult to conceptualize because of both the time frame involved and the natural process by which they cyclically unfold.

Four geologists and two mountain guides face the brutal beauty of West Antarctica eight hundred miles from the United States main base. Their search reaches far into the treacherous mountains of Marie Byrd Land. Over six weeks of living in tents and traveling by snowmobile, the team endures endless cold and furious blizzards. They cross ice fields and hidden crevasses, which one of the team learns about the hard way.

Devastating natural disasters have profoundly shaped human history, leaving us with a respect for the mighty power of the Earth - and a humbling view of our future. Paleontologist and geologist Donald R. Prothero tells the harrowing human stories behind these catastrophic events.

In an easy conversational style, The Restless Northwest provides a brief overview of the remarkable geological processes that have shaped the Pacific Northwest. The narrative is also sprinkled with firsthand accounts of the people involved in recent exciting, scientific discoveries. Williams enlivens this story of long-ago geologic events, with a variety of fascinating asides, on everything from enormous undersea tubeworms, to the Willamette meteorite.

Matthew Hart embarks on a journey into the largely hidden and fascinating world that is the diamond trade. The geology of diamonds explains how hard it is to find them. They are accidents of nature, carbon crystals compressed underground for eons. Weaving science and history, Hart follows the diamond trail from the basement where Gabi Tolkowsky, the world's greatest cutter, faced the 599-carat Centenary diamond, to Africa's Diamond Coast, to the sales rooms of De Beers.

This Introduction audiobook explores emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth as it actually is: dynamic and ever-changing.

This easy-to-understand book describes what happened to planet Earth during and after the 371 days that Noah and seven others remained secure inside the ark. They left behind a one-continent world and landed in a newly shattered world, the one great land mass having been ripped apart into the continents we know today. Stones and bones tell the story.

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).

In 1938 the discovery of a large, unusual fish turned the scientific community on end. Dubbed a living fossil, the discovery of a coelacanth in South Africa shocked scientists around the world who thought this type of fish had died out millions of years prior during the process of evolution. Living fossils are organisms found preserved in the fossil record, which still exist in similar form today. If the core concepts of the theory of evolution presuppose change over time, then how can these living fossils exist for millions of years remaining virtually unchanged? Whether a shark, leaf, or ...

Rare Earth Frontiers is a work of human geography that serves to demystify the powerful elements that make possible the miniaturization of electronics, green energy and medical technologies, and essential telecommunications and defense systems. Julie Michelle Klinger draws attention to the fact that the rare earths we rely on most are as common as copper or lead, and this means the implications of their extraction are global. Klinger excavates the rich historical origins and ongoing ramifications of the quest to mine rare earths in ever more impossible places.

You've heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents, but what about its predecessors, Rodinia or Columbia? These "supercontinents" from Earth's past provide evidence that land repeatedly joins and separates. While scientists debate what that next supercontinent will look like—and what to name it—they all agree: one is coming.

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.

Most of us who have an interest in the planet we live on have seen diagrams showing the Earth’s interior. We are told it is very hot and made of iron. Is this really true? How far have we actually “dug down” to find this “hot ball of iron”? Where did our enormous oceans come from and have they always been here? And anyway, how did our planet form? Have you ever looked at a map and noticed how the west coast of Africa seems to fit against the east coast of South America – as if they were pieces of some enormous continental jigsaw? Has our planet always been the same size, or has ...

This audiobook includes an introduction to basics of where to find gold, what materials you need, and a bunch of other tips that will increase your odds of finding gold.

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.

Over the past few years, devastating tsunamis off the coast of the Indian Ocean have killed hundreds of thousands of people. Even more alarmingly, scientists predict that these tsunamis, as well as a series of earthquakes and volcanic eruptions, will be striking with even greater frequency and may eventually threaten Hawaii, California, and Oregon.

Darius Cobb wasn't thinking of man's extinction. He honestly never gave it a thought. A college professor and part time country singer, Darius worried only about teaching and playing his guitar until the day he is attacked by cockroaches and is placed into a special government quarantine. There, he and the others start piecing together the inevitable. Using his knowledge, he begins predicting the events that unfold. Together he and his group plan and then implement a long term survival plan.

Meteorites, methane, mega-volcanoes and now human beings; the old forces of nature that transformed Earth many millions of years ago are joined by another: us. Our actions have driven Earth into a new geological epoch, the Anthropocene. For the first time in our home planet's 4.5-billion year history a single species is dictating Earth's future. To some the Anthropocene symbolises a future of superlative control of our environment. To others it is the height of hubris, the illusion of our mastery over nature.
