This book explains how the new Earth System approach to Earth Science is revolutionizing our understanding of Earth processes and changes. Separate chapters cover the Earth’s major systems (atmosphere, hydrosphere cryosphere, geosphere, and biosphere); the Big Bang theory of the universe’s origin; geology and the geologic time scale; plate tectonics and continental drift; weathering and erosion; the world’s oceans and atmosphere; environmental considerations, and much more.

Barron’s continues its ongoing project of improving, updating, and giving contemporary new designs to its popular Easy Way books, now re-named Barron’s E-Z Series. The new cover designs reflect the books’ brand-new page layouts, which feature extensive two-color treatment, a fresh, modern typeface, and many more graphics. In addition to charts, graphs, and diagrams, the graphic features include instructive line illustrations, and where appropriate, amusing cartoons. Barron’s E-Z books are self-teaching manuals designed to improve students’ grades in many academic and practical subjects. In most cases, the skill level ranges between senior high school and college-101 standards. In addition to their self-teaching value, these books are also widely used as textbooks or textbook supplements in classroom settings. E-Z books review their subjects in detail and feature short quizzes and longer tests to help students gauge their learning progress. All exercises and tests come with answers. Subject heads and key phrases are set in a second color as an easy reference aid.
