AMAZING PLANET looks at the geological upheaval and natural elements that created the landscape of today's earth and continue to sculpt and refine the planet as time goes on. Presented in high definition, the series demonstrates how the destructive forces of wind, water, and fire combine to etch the topography of the world's continents. Time-lapse photography and detailed computer graphics illustrate the deterioration and regeneration of land through erosion and volcanic action, as well as the eons-long shifting of the continents into their present-day position. Viewers are treated to a whirlwind global tour of some of the planet's natural wonders as narrator Patricia Clarkson explains the processes behind the creation of tumbling waterfalls, towering desert stone formations, cavernous canyons, and stalactite-filled caves. For example, a segment spotlighting the destructive force of water describes how, over time, the powerful Colorado River carved out the massive Grand Canyon and how glaciers formed the Great Lakes and nearby majestic Niagara Falls, whose ledges continue to deteriorate under the force of the hundreds of thousands of gallons of water that rush over them every second.
