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.

Take a look at how earthquakes are measured in this excellent program. Seismologists from the National Earthquake Center in Golden, Colorado show how earthquake epicenters are located. You will observe an actual earthquake being captured and the measurement scales, both Mercalli, and Richter are explained. You will also see an example of triangulation in capturing earthquake data.

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.

Geologic Time refers to the millions or even billions of years in which the processes and forces that shape the earth took place. Learn why and how scientists use this time scale and why it is divided into Eras, Epochs and Periods. Explore how geologists use potassium-argon dating to determine the age of rocks and minerals. Visit Ohio State University’s dating lab and see the dating process in action.

Running water changes the surface of the earth by cutting away rock in one place, carrying this load and then depositing it in another place. This program explores the relationship of running water to the land. Concepts investigated include suspension, solution, load, rapids, potholes, meanders, braided streams, deltas, alluvial fans, waterfalls and flood plains. The program also explores characteristics found in youthful, mature and old streams.

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.

One of the three basic types of rock, sedimentary rocks include sandstone, limestone, siltstones, coquina, mudstones, shale, dolomites, conglomerates, fossil limestone and sandstones. This program investigates how weathering breaks up rock and the this sediment is later turned into the various kinds of clastic and non-clastic rocks. The program also shows how students can make sedimentary rock using simple, everyday materials.

The third classification of rocks are those which were formed deep in the earth’s crust by melting and then recrystallization. These rocks include volcanic rocks, igneous rocks of dykes and sills and plutonic rocks such as granite, syenite, gabbro and ultramafic rocks. Many specimens are discussed that are not often found in classroom labs or textbooks.
