Description

The surface of the Earth has undergone many changes over its history. Natural forces such as wind, rain, temperature and the activity of living things continually shape the visible landscape. In All About Weathering and Erosion, children will discover how these forces combine to form Earth's features. Examine the different forms of physical and chemical weathering that affect the Earth, while touching on both the problems and benefits that erosion has on the people who inhabit the land. An informative, hands-on demonstration shows how to construct a model glacier in order to see the effects glaciers have on the Earth, while a visit to Mt. Rushmore examines the effects of weathering on the world's largest sculpture. Part of the Earth Science for Children DVD Series. A teacher's guide is available online. 23 minutes. Grades K to 4.
