Earth Geology

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.

What is deep within the core?

In Tibet, geologist David R. Montgomery heard a local story about a great flood that bore a striking similarity to Noah’s Flood. Intrigued, Montgomery began investigating theworld’s flood stories and - drawing from historic works by theologians, natural philosophers, and scientists - discovered the counterintuitive role Noah’s Flood played in the development of both geology and creationism.

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.

In 2018, lumps of frozen soil, collected from the bottom of the world's first deep ice core and lost for decades, reappeared in Denmark. When geologist Paul Bierman and his team first melted a piece of this unique material, they were shocked to find perfectly preserved leaves, twigs, and moss. That observation led them to a startling discovery: Greenland's ice sheet had melted naturally before, about 400,000 years ago.

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.

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).

The thrilling story of the charismatic explorer who Simon Bolivar called "the true discoverer of South America" and the daring expedition that altered the course of science. From 1799 to 1804 German naturalist and adventurer Alexander von Humboldt conducted the first extensive scientific exploration of Latin America.

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.

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.

In this Very Short Introduction, William Lowrie describes the internal and external processes that affect the planet, as well as the principles and methods of geophysics used to investigate them. From analyses of Earth's deepest interior to measurements made from Earth-orbiting satellites, Lowrie shows how geophysical exploration is vitally important in the search for mineral resources and emphasizes our need to understand the history of our planet and the processes that govern its continuing evolution.

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.

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.

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 ...

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 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.

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.

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.

End Times is a compelling work of skilled reportage that peels back the layers of complexity around the unthinkable - and inevitable - end of humankind. From asteroids and artificial intelligence to volcanic supereruption to nuclear war, veteran science reporter and TIME editor Bryan Walsh provides a stunning panoramic view of the most catastrophic threats to the human race.

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.
