Earth The Sapphire Planet

With some 70 percent of its surface covered by water, the Earth presents a picture of a gemlike blue planet when viewed from outer space. This sapphire jewel — the only planet in our solar system to sustain intelligent life — is the subject of this remarkably engaging and concise book by biologist, teacher, and popular science writer Url Lanham. Focusing on the Earth and the life forms that have evolved on it, Mr. Lanham's captivating study covers a wide range of subjects — from the work of Galileo, Copernicus, Herschel, and other scientists who contributed to our knowledge of Earth's position in the universe, to the Earth's internal physiology, intricacies of the biosphere, creation of continents, origins of plant and animal life, the diversity of physical habitats in which these life forms thrive, and much more. Well written and highly readable, this absorbing and optimistic natural history of the planet will take readers on a fantastic journey through time, offering up a host of facts and provocative insights. Easily accessible to advanced high school science students and college undergraduates, Earth, the Sapphire Planet will be warmly received as well by teachers and ecologically aware general readers.

Explore and understand the natural and human wonders of our planet Now in its third edition, this landmark encyclopedia both celebrates our planet and explains the science underpinning the forces and processes that have made and shaped it. Artworks, photographs, terrain models, and maps are used in combination to capture the beauty and power of landscapes and natural events and to show their hidden sides, explaining for example how an earthquake is triggered and how burning fossil fuels is driving a climate emergency. Directory sections placed throughout the book provide systematic and in-depth reference guides to core scientific information, such as more than 100 types of rocks and minerals. Similar sections contain visual profiles of some of the undisputed wonders of the natural world, from the Andes and Himalayas to the Grand Canyon, Sahara Desert, and Amazon Rainforest. Thoroughly revised and updated to include new and spectacular landscape photography and capture the latest developments in fast-changing areas of geology and Earth science—including Earth history, climate change, and urban geography—this is an indispensable visual reference book for anyone who wants to understand how our planet works.
