There are two major pathways for the flow of energy and matter on Earth: (1) the hydrologic system-the circulation of water over Earth's surface and through its atmosphere powered by energy from the Sun, and (2) the tectonic system-the movement of material powered by heat from Earth's interior. These two unifying themes form the backbone ofEarth's Dynamic Systems,providing a logical, well-crafted, spectacularly illustrated introduction to physical geology. NEW TO THIS EDITION:GeoLogic-Geologists have a unique way of "reading" the landscape and rocks. These essays illustrate in words and images how modern geologists interpret the world around us. Updated and Enhanced Student CD-ROM:Includes dozens of high-quality animations, photographs, and videos. Guided Tours:These animated tours of Earth's major landforms illustrate key concepts in a way the printed word and still pictures cannot. Slideshows:Written and photographed by the authors, the slideshows expand on the text with additional photographs and explanations. Videos and animations:Gathered from geologists around the world, these illustrate both fundamental concepts and how modern geologists study EarthHamblin, W.
