“This set provides well-selected graphics to illustrate important concepts in Earth Science. The material is visually stimulating and sequenced in an effective order to support good classroom activities. Earth in Action videos are especially appropriate for middle school students and beginners but would also help secondary students who need review…It would also be helpful to curriculum specialists who are working with newer teachers or teachers who need a quick review of basic concepts for an Earth science unit.”

Plate Tectonics

Students will explore how the discoveries of specific fossils, the geographic fit of the continents, ocean floor magnetic fields, young ocean rocks, and seafloor spreading provide evidence to support the theory of plate tectonics. Exciting footage from Iceland helps illustrate the power of tectonic movement. Other terminology includes: continental drift, Pangaea, tectonic plates, plate boundaries, mountain building, folding, faulting, and landforms.

Volcanoes and Earthquakes

Footage of volcanic activity in Iceland and Hawaii, as well as earthquake events in California, illustrate how these dynamic forces affect our world. Through descriptions of actual volcanic and earthquake occurrences, students will discover how these dynamic forces affect our world. The video discusses the nature and causes of earthquakes and volcanoes. Other terminology includes: molten rock, magma, lava, cinder cone, shield volcano, composite volcano, caldera, Ring of Fire, seismic waves, seismograph, and Richter Scale.

Forces Shaping the Earth

Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion, and the major types of mass movements caused by gravity are discussed in this video. Other terminology includes: folding, faulting, deposition, creep, mass movement, landslide, surface runoff, alluvial fan, delta, stream erosion, beach erosion, ice erosion, wind erosion, dune, glaciers, glacial deposits.

Weathering and Soils

In this video students will learn about the two major types of weathering, and the forces that alter the shape and composition of rocks. Students will explore the different types of soils, soil properties and the soil profile. Other terminology includes: mechanical weathering, chemical weathering, oxidation, soil formation, soil texture, horizons, leaching, subsoil, soil conservation, and groundwater.
