Did you know that millions of years ago the Earth only had one super continent? If you look at a globe today, you’d notice how continents fit into each other like puzzle pieces. But how did the super continent break apart and become seven different continents? Let’s look at the mechanics of the continental drift in this book for fifth graders. Grab a copy today.
Explores the Supercontinent Cycle from the earliest recorded time to the geological discoveries of today including the drifting of the continents and the evolution of dinosaurs.
A source of profound influence and controversy, this landmark 1915 work explains various phenomena of historical geology, geomorphy, paleontology, paleoclimatology, and similar areas in terms of continental drift. 64 illustrations. 1966 edition.
Learn how the continents have changed throughout time and how continental drift has influenced the world we live in today! Explore how the continents have drifted, from the Devonian Era to the Jurassic Period, to form the world as we know it! This beautiful book will take readers through different periods and explore the ecosystems and conditions of each time and how the changes led to where we are now. Learn about sea life, insects, animals, plants, rocks, and more! This book will be sure to capture the attention of young readers and educate them in the process!
Travel with me, if you will, on this incredible journey spanning millions of years from when Pangea begin its development towards becoming a single, supercontinent to its break up to form what we know as todays' seven continents, each rich in treasure. Detect, if you can, the unique secrets left behind in Pangea's wake that will lead us to hidden treasures and hidden dangers. Do not delay your journey, for others are trying to discover the still hidden treasures and hidden dangers. Will you be next to find unimaginable wealth? Will you be able to detect the hidden dangers?
Fifty years ago, no one could explain mountains. Arguments about their origin were spirited, to say the least. Progressive scientists were ridiculed for their ideas. Most geologists thought the Earth was shrinking. Contracting like a hot ball of iron, shrinking and exposing ridges that became mountains. Others were quite sure the planet was expanding. Growth widened sea basins and raised mountains. There was yet another idea, the theory that the world's crust was broken into big plates that jostled around, drifting until they collided and jarred mountains into existence. That idea was invariably dismissed as pseudo-science. Or "utter damned rot" as one prominent scientist said. But the doubtful theory of plate tectonics prevailed. Mountains, earthquakes, ancient ice ages, even veins of gold and fields of oil are now seen as the offspring of moving tectonic plates. Just half a century ago, most geologists sternly rejected the idea of drifting continents. But a few intrepid champions of plate tectonics dared to differ. The Mountain Mystery tells their story.
The Pulitzer Prize-winning view of the continent, across the fortieth parallel and down through 4.6 billion years Twenty years ago, when John McPhee began his journeys back and forth across the United States, he planned to describe a cross section of North America at about the fortieth parallel and, in the process, come to an understanding not only of the science but of the style of the geologists he traveled with. The structure of the book never changed, but its breadth caused him to complete it in stages, under the overall title Annals of the Former World. Like the terrain it covers, Annals of the Former World tells a multilayered tale, and the reader may choose one of many paths through it. As clearly and succinctly written as it is profoundly informed, this is our finest popular survey of geology and a masterpiece of modern nonfiction. Annals of the Former World is the winner of the 1999 Pulitzer Prize for Nonfiction.
As soon as early humans began to scratch images on cave walls, they began to create maps. And while these first drawings were used to find hunting grounds or avoid danger, they later developed into far more complex navigational tools. Charting the World tells the fascinating history of maps and mapmaking, navigators and explorers, and the ways that technology has enhanced our ability to understand the world around us. Richly illustrated with full-color maps and diagrams, it gives children an in-depth appreciation of geographical concepts and principles and shows them how to unlock the wealth of information maps contain. It also features 21 hands-on activities for readers to put their new skills to the test. Children will: build a three-dimensional island model using a contour map, engrave a simple map on an aluminum &“printing plate,&” determine the elevation of hills in their neighborhood, draw a treasure map and have a friend search for the hidden stash, create a nautical chart of a small puddle, survey their backyard or local park, navigate a course using a compass, and much more. Now more than ever, the study of geography is crucial to understanding our ever-changing planet, from political change and warfare to environmental conservation and population growth.
