The Earth is made of layers, each with its own unique characteristics and processes that make it a vital part of the planet. The solid inner core, for example, is the farthest layer from the planet's surface, yet it provides much of the heat needed to fuel dramatic surface phenomena . Likewise, the outer core generates a magnetic field that protects the planet from harmful particles in space. In "Layers of the Earth", learn how scientists use modern tools land global positioning systems to study the workings of the inner Earth.

Psychoanalyst Jean Bolen's career soared in the early 1980s when Goddesses in Everywoman was published. Thousands of women readers became fascinated with identifying their own inner goddesses and using these archetypes to guide themselves to greater self–esteem, creativity, and happiness.

Bolen's radical idea was that just as women used to be unconscious of the powerful effects that cultural stereotypes had on them, they were also unconscious of powerful archetypal forces within them that influence what they do and how they feel, and which account for major differences among them. Bolen believes that an understanding of these inner patterns and their interrelationships offers reassuring, true–to–life alternatives that take women far beyond such restrictive dichotomies as masculine/feminine, mother/lover, careerist/housewife. And she demonstrates in this book how understanding them can provide the key to self–knowledge and wholeness.

Dr. Bolen introduced these patterns in the guise of seven archetypal goddesses, or personality types, with whom all women could identify, from the autonomous Artemis and the cool Athena to the nurturing Demeter and the creative Aphrodite, and explains how to decide which to cultivate and which to overcome, and how to tap the power of these enduring archetypes to become a better "heroine" in one's own life story.
