Take a unique look at the Earth as you examine its natural processes, complex systems and the reciprocal relationship between people and Earth’s natural environment. Written by three of today’s most respected geographers, Petersen/Sack/Gabler’s PHYSICAL GEOGRAPHY, 12E introduces geography from three perspectives: as a physical science, a spatial science and an environmental science. A reader-friendly presentation demonstrates the processes and interactions among Earth’s systems and emphasizes environmental sustainability – highlighting how natural systems are affected by human activities and how natural processes impact human lives. Updated, compelling visuals illustrate concepts with vivid photos, helpful figures and information-rich maps. This edition also explores dynamic areas of the Earth, such as the Pacific Ring of Fire, and examines the latest digital and drone technologies used in geographical research. MindTap digital tools and videos are available to assist in review.
