Forces that shape our earth: Explore the major landforms of our world with spectacular video footage. Look at the various forces that affect our physical environment including glaciers, volcanoes, gravity, rivers, lakes and oceans, movement in the earth, wind and temperature changes. This video is a superb introduction to the ways all these forces work together to shape our planet.

Glaciers that shape our earth: Glaciers have had a more profound effect on the surface of the earth than probably any other geological process. This is the one audiovisual aid you SHOULD have to explain the world of glaciers to your students. This video clearly investigates what glaciers do and how they affected most of North America.

The hydrologic cycle: Examines one of the most important processes that affect life on earth. The water cycle is covered from transpiration through evaporation to condensation, precipitation and run-off.

Waves, coastlines and beaches: This live-action video deals with the geological processes that take place where ocean meets land. Learn how erosional and depositional processes form features such as rugged coastlines, barrier islands, spits, Tombolos, wave cut terraces sea stacks and beaches. Animated sequences take you underwater to show processes underway just off the shoreline.

Underground water: Discusses how water is trapped between grains of rock underground. Discover wells, water flow, hydrology, artesian wells and the water table.

Why is the ocean salty: All water, even rainwater contains dissolved chemicals which scientists call "Salts." These salts eventually wash down into rivers and streams and eventually find their way into oceans and seas. Subjects covered include: The origin of the sea. The sources of salt. The components of sea water. The salinity of the sea and its variability. How sea life affects sea waters composition.

Geology of caves and caverns: Illustrates what water can do below the earth's surface, over long periods of time. Using animated and real life sequences, this program explores some important caves, their formations and teaches students how underground water dissolves limestone to form caves, caverns, stalagmites, stalagtites and boxfork formations.

Ages 10+.
