Horizons

HORIZONS: EXPLORING THE UNIVERSE, Enhanced Thirteenth Edition, will help you understand your place in the universe-not just your location in space but your role in the unfolding history of the physical universe. To achieve this goal, they focus on two central questions: &quote;What Are We?&quote; which highlights your place as a planet dweller in an evolving universe, guiding you to a better understanding of where we came from and how we formed; and &quote;How Do We Know?&quote; which provides insights into how science works and how the process of science can teach us more about what we are. In this edition, all end-of-chapter material is available online in the MindTap homework system, and there is a MindTap Reader version available to students.
