That evidence, he argues, shows that 700 million years ago the Earth did indeed freeze over completely, becoming a giant “snowball,” in the worst climatic catastrophe in history. Even more startling is his assertion that, instead of ending life on Earth, this global deep freeze was the trigger for the Cambrian Explosion, the hitherto unexplained moment in geological time when a glorious profusion of complex life forms first emerged from the primordial ooze.In a story full of intellectual intrigue, we follow the irascible but brilliant Hoffman and a supporting cast of intrepid geologists as they scour the planet, uncovering clue after surprising clue. We travel to a primeval lagoon at Shark Bay in western Australia, where dolphins cavort with swimmers every morning at seven and “living rocks” sprout out of the water like broccoli heads; to the desolate and forbidding ice fields of a tiny Arctic archipelago seven hundred miles north of Norway; to the surprising fossil beds that decorate Newfoundland’s foggy and windswept coastline; and on to the superheated salt pans of California’s Death Valley.Through the contours of these rich and varied landscapes Walker teaches us to read the traces of geological time with expert eyes, and we marvel at the stunning feats of resilience and renewal our remarkable planet is capable of. Snowball Earth is science writing at its most gripping and enlightening.

    Sibert Medal-winning author Sally M. Walker covers Earth's many marvels -- fossilized skeletons of plants and animals, terrific volcanic eruptions, the never-ending hydrologic cycle -- in sometimes straightforward, sometimes metaphoric three-line haikus. Expertly drawn art by William Grill, author-illustrator of Shackleton's Journey, provides a visual reference for each poem. In clear and creative back matter, Walker and Grill further use their skills to provide additional detailed explanations for the science behind each concept. A unique, artistic intersection of poetry and science, Earth Verse is sure to enthrall any and all readers interested in the world around them.

    Bangar is a book that is designed as a basic text for the students of B.Sc in Geology, B.E. in Civil Engineering and Mining Engineering, A.M.I.E. Section B, and also Diploma In Mining Engineering. This book can also be referred to by those who are appearing for the different competitive examinations conducted by the U.P.S.C. and other State PSCs. The book also provides the required information for the keen readers of Geology. Principles Of Engineering Geology covers topics such as physical geology, minerals, study of various crystals, and also the different types of rocks, such as igneous, sedimentary, and metamorphic rocks. The book also covers different geological structures and the Indian geology. Some of the other topics that are covered in the book are different deposits of ore and the role of engineering in geology. Various methods of exploration and surveying techniques are also covered in the book.K.M. Bangar is also the author of Engineering and General Geology.

    In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.

    The result is The Backbone of the World, an arresting exploration of America’s longest wilderness corridor, a harsh and unforgiving region inhabited by men and women whose way of life is as imperiled as the neighboring wildlife. With the brutal beauty and stark cadences of a Cormac McCarthy novel, The Backbone of the World tells the story of the last remnants of the Old West, America’s mythic landscape, where past and present are barely discernible from one another and where people’s lives are still intrinsically linked to their natural surroundings. Clifford vividly captures the challenges of life along the Divide today through portraits of memorable characters: a ranching family whose isolated New Mexico homestead has become a mecca for illegal immigrants and drug smugglers; a sheep herder struggling to make a living tending his flock in the mountains above Vail, Colorado: an old mule packer who has spent years scouring the mountains of northwest Wyoming for the downed plane of his son; a Yellowstone Park ranger on a lone crusade to protect elk and grizzly bears from illegal hunters; and a group of Blackfeet Indians in northern Montana who are fearful that a wilderness sanctuary will be lost to oil and gas development. In each of their stories, the tide of change is looming as environmental, economic, social, and political forces threaten this uniquely unfettered population. Clifford’s participatory approach offers a haunting and immediate evocation of character and geography and an unsentimental eulogy to the people whose disappearance will sever a link with the defining American pioneer spirit. Set in a world of isolated ranches, trail camps, mountain bivouacs, and forgotten hamlets, The Backbone of the World highlights the frontier values that have both ennobled and degraded us, values that symbolize the last breath of our founding character.From the Hardcover edition.
