Earth Geology

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.

The fascinating, often surprising story of how a simple black rock altered the course of history. Yet the mundane mineral that built our global economy, and even today powers our electrical plants, has also caused death, disease, and environmental destruction. In this remarkable book, Barbara Freese takes us on a rich historical journey that begins three hundred million years ago and spans the globe.

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?

This Very Short Introduction takes listeners into the inferno of a racing pyroclastic current, and the heart of a moving lava flow, as understood through the latest scientific research. Exploring how volcanologists forensically decipher how volcanoes work, Michael Branney and Jan Zalasiewicz explain what we do (and don't) understand about the fundamental mechanisms of volcanism, and consider how volcanoes interact with other physical processes on the Earth, with life, and with human society.

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 ...

Tim Flannery’s first major book since The Weather Makers charts the history of life on our planet. Here on Earth, which draws its points of departure from Darwin and Wallace, Lovelock and Dawkins, is an extraordinary exploration of evolution and sustainability. Our success as a species has had disastrous effects on many of the Earth’s ecosystems and could lead to our downfall. But equally, Flannery argues, we are now equipped as never before to explore our true relationship with the planet on which our biological, economic and cultural futures depend.

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).

From the oldest rocks, formed three billion years ago in Karnataka, to the arrival of our ancestors 50,000 years ago on the banks of the Indus, the author meticulously sifts through wide-ranging scientific disciplines and through the layers of earth to tell us the story of India, filled with a variety of fierce reptiles, fantastic dinosaurs, gargantuan mammals and amazing plants.

In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.

Antarctica, the ice kingdom hosting the South Pole, looms large in the human imagination. The secrets of this vast frozen desert have long tempted explorers, but its brutal climate and glacial shores notoriously resist human intrusion. Land of Wondrous Cold tells a gripping story of the pioneering 19th-century voyages, when British, French, and American commanders raced to penetrate Antarctica’s glacial rim for unknown lands beyond. These intrepid Victorian explorers laid the foundation for our current understanding of Terra Australis Incognita.

Serendipity placed David Johnston on Mount St. Helens when the volcano rumbled to life in March 1980. Throughout that ominous spring, Johnston was part of a team conducting scientific research that underpinned warnings about the mountain. Those warnings saved thousands of lives when the most devastating volcanic eruption in U.S. history blew apart Mount St. Helens but killed Johnston on the ridge that now bears his name. Melanie Holmes tells the story of Johnston's journey from a nature-loving Boy Scout to a committed geologist.

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.

We need a new philosophy of the earth. Geological time used to refer to slow and gradual processes, but today we are watching land sink into the sea and forests transform into deserts. We can even see the creation of new geological strata made of plastic, chicken bones, and other waste that could remain in the fossil record for millennia or longer. Crafting a philosophy of geology that rewrites natural and human history from the broader perspective of movement, Thomas Nail provides a new materialist, kinetic ethics of the earth that speaks to this moment.

Masterfully tying together history, science, and human drama, The Lost Dinosaurs of Egypt is the gripping account of two of the 20th century's great expeditions of discovery. In 1911 a German paleontologist found the remains of four entirely new dinosaurs in the Egyptian desert, but in a single night, all of his work was destroyed. Eighty-nine years later, an American grad student leads an expedition to unearth Stromer's dinosaur graveyard, and in doing so, he stuns the scientific world.

A thrilling scientific investigation and the portrait of an extraordinary genius, The Seashell on the Mountaintop gives us new insight into our planet, revealing how we learned to read the story told to us by the Earth itself, written in rock and stone.

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.

Aluminum is the most abundant metal in the earth’s crust. It is also ubiquitous in the modern world, from aircraft to soda cans. A dizzying number of consumer and industrial products employ aluminum, typically alloyed, because of its availability, versatility, and malleability. Today, how efficiently we use—and reuse—aluminum is vital to addressing key environmental challenges and understanding humanity’s fraught relationship with the earth.

This pathbreaking book explores how life can begin, taking us from cosmic clouds of stardust, to volcanoes on Earth, to the modern chemistry laboratory. Seeking to understand life's connection to the stars, David Deamer introduces astrobiology, a new scientific discipline that studies the origin and evolution of life on Earth and relates it to the birth and death of stars, planet formation, interfaces between minerals, water, and atmosphere, and the physics and chemistry of carbon compounds.

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 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.
