Objective review questions have been placed at the end of each teaching section to facilitate review of daily reading assignments. Subjective review questions have been placed at the end of each chapter for more thorough chapter reviews and evaluations. Thought provoking "What do you Think?" questions have been added and can be incorporated into your lectures and discussions to stimulate interest. A chapter overview and suggested teaching schedule are included at the beginning of each chapter. Most other teaching aids have been placed in the margins of the appropriate chapters rather than lumped together at the front or end of the book.

This Earth Science curriculum gives students a clear understanding of the planet on which they live by giving them a view of the environment in which it is found. This study begins with a study of space because the planets, stars, and all other heavenly bodies "float" in the ocean of space, and these bodies affect one another.
