Welcome to physical geography and the fifth edition of Geosystems! We begin this new century with a sense that the world community is responding to global concerns as to the status and conditions of Earth's physical, biological, and chemical systems. The globalization of the world economies seems paralleled by a global scientific inquiry into the state of the environment. Marking this awareness is the second Earth Summit held in 2002 in Johannesburg, South Africa, with an agenda including climate change, freshwater, and the five Rio Conventions, among other topics.
Armed with the spatial analysis tools of geographic science, physical geographers are well equipped to participate in a planetary understanding of environmental conditions. U.N. Secretary General Kofi Annan, recipient of the 2001 Nobel Peace Prize, spoke to the Association of American Geographers annual meeting in 2001, stating,
As you know only too well the signs of severe environmental distress are all around us .... The idea of interdependence is old hat to geographers, but for most people it is a new garment they are only now trying on for size . . . I look forward to working with you in that all-important journey.
This edition of Geosystems, with its contemporary global scope, builds on the success achieved by the first four editions in the United States, Canada, and elsewhere. Students and teachers alike continue to express appreciation for the systems organization, readability, scientific accuracy, up-to-date coverage and relevancy, clarity of the summary and review sections, the functional beauty of the photographs, art,cartography, and the many integrated figures in the text that combine media.
Geosystems Communicates the Science of Physical Geography
The goal of physical geography is to explain the spatial dimension of Earth's dynamic systems—its energy, air, water, weather, climate, tectonics, landforms, rocks, soils, plants, ecosystems, and biomes. Understanding human-Earth relations is part of the challenge of physical geography—to create a holistic (or complete) view of the planet and its inhabitants.
Geosystems analyzes the worldwide impact of environmental events, synthesizing many physical factors into a complete picture of Earth system operations. A good example is the eruption of Mount Pinatubo in the Philippines. The global implications of this major event (one of the largest eruptions in the 20th century) are woven through seven chapters of the book (see Figure 1.6 for a summary). Our update on global climate change and its related potential effects is part of the fabric in six chapters. These content threads weave together the variety of interesting and diverse topics crucial to a thorough understanding of physical geography.
This edition of Geosystems features more than 500 photographs from across the globe and 105 remote-sensing images from a wide variety of orbital platforms. Twenty-nine of these images are from the Terra satellite and its five sensor packages. To assist with spatial analysis and location, 121 maps are utilized, and more than 300 illustrations explain concepts.
Systems Organization Makes Geosystems Flow
Each section of this book is organized around the flow of energy, materials, and information. Geosystems presents subjects in the same sequence in which they occur in nature. In this way you and your teacher logically progress through topics which unfold according to the flow of individual systems, or in accord with time and the flow of events. See Figure 1.7 in the text for an illustration of this systems organization.
For flexibility, Geosystems is divided into four parts, each containing chapters that link content in logical groupings. The diagram on the next page from Figure 1.8 illustrates our part structure. A quick check of the Table of Contents and this illustration shows you the order of chapters within these four parts.
The text culminates with Chapter 21, "Earth and the Human Denominator," a unique capstone chapter that summarizes physical geography as an important discipline to help us understand Earth's present status and possible future. Think of the world's population and the totality of our impact as the human denominator. Just as the denominator in a fraction tells how many parts a whole is divided into, so the growing human population and the increasing demand for resources and rising planetary impact suggest how much the whole Earth system must adjust. This chapter is sure to stimulate further thought and discussion, dealing as it does with the most profound issue of our time, Earth's stewardship.
Geosystems is a Text That Teaches
Teaching and learning begin with the front and back cover images of the Pacific Northwest, two detail photos, and locator map. Geosystems is written to assist you in the learning process. Three heading levels are used throughout the text and precise topic sentences begin each paragraph to help you outline and review material. Boldface words are defined where they first appear in the text. These terms and concepts are collected in the Glossary alphabetically, with a chapter-number reference. Italics are used in the text to emphasize other words and phrases of importance. Every figure has a title that summarizes the caption. Also, in the introduction to each chapter, a new feature called "In this chapter:" gives you an overview.
An important continuing feature is a list of Key Learning Concepts that opens each chapter, stating what you should be able to do upon completing the chapter. These objectives are keyed to the main headings in the chapter. At the end of each chapter is a unique Summary and Review section that corresponds to the Key Learning Concepts. Grouped under each learning concept is a narrative review that redefines the boldfaced terms, a key terms list with page numbers, and specific review questions for that concept. You can conveniently review each concept, test your understanding with review questions, and check key terms in the glossary, then return to the chapter and the next learning concept. In this way, the chapter content is woven together using specific concepts.
A Critical Thinking section ends each chapter, challenging you to take the next step with information from the chapter. The key learning concepts help you determine what you want to learn, the text helps you develop information and more questions, the summary and review helps you assess what you have learned and what more you might want to know about the subject, and the critical thinking provokes action and application.
New Career Link essays feature geographers and other scientists in a variety of professional fields practicing their spatial analysis craft. You will read about an astronaut with over 1200 hours in orbit, a weather forecaster at the Forecast Systems Lab, an environmental scientist, a hydrologist with the National Weather Service, a snow avalanche specialist, and an expert on global scale ecosystems, among others.
Coverage of Canadian physical geography in the text and figures throughout the book continues. Canadian data en a variety of subjects are portrayed on 30 different maps in combination with the United States—physical geography does not stop at the United States-Canadian border!
Twenty "Focus Study" essays, some completely revised and several new to this edition, provide additional explanation of key topics. A few examples from this diverse collection include: the stratospheric ozone predicament, solar energy collection and wind power, the newly (2001) calibrated wind-chill chart, forecasting the near-record 1995-2000 hurricane seasons, the 1997-1998 El Nino phenomenon, geothermal energy development, status of the High Plains Aquifer using new maps, floodplain strategies, an environmental approach to shoreline planning, the Mount St. Helens eruption, the 2001 status of the Colorado River, and the continuing global loss of biodiversity.
Forty-three "News Reports" relate topics of special interest. For example: GPS, careers in GIS, a 34-kilometer sky dive to study the atmosphere, jet streams and airline flight times, how one culture harvests fog, the UV Index, coordination of global climate change research with many URLs presented, the disappearing Nile Delta, water issues in the Middle East, artificial scouring of the Grand Canyon to restore beaches and habitats, how sea turtles read Earth's magnetic field, alien and exotic plant and animal invasions, and threats to the Arctic National Wildlife Refuge.
We now live on a planet served by the Internet and its World Wide Web, a resource that weaves threads of information from around the globe into a vast fabric. The fact that we have Internet access into almost all the compartments aboard Spaceship Earth is clearly evident in Geosystems. Many entry points link directly from the words in a chapter to an Internet source allowing you to be up-to-the minute in understanding the facts. You will find more than 200 URLs (Internet addresses) in the body of the text (printed in blue color and boldface). Given the fluid nature of the Internet, URLs were rechecked at press time for accuracy. If some URLs changed since publication, you can most likely find the new location using elements of the old address. Textbooks, especially in dynamic fields like geography must be tapped into these streams of scientific discoveries and environmental events. This Internet link begins with a new Table 1.1 presenting the URLs for major geography organizations.
