Over the course of its 4.5 billion-year history, Earth has undergone a great number of changes -- from a red-hot ball of molten lava to a planet with an environment capable of sustaining life. In All About Earth's History, children will trace the evolution of Earth and the organisms that populate it. Young viewers will take a peek deep inside the Earth, examining its varied layers while discussing how scientists use fossils to help map out the complex time line of events that has changed Earth over millions of years. A visit to the Grand Canyon examines the rock layers of this famous land formation, revealing how the climate of the region has changed over time. A lively, hands-on activity demonstrates how scientists use core samples to study the Earth.
