Our Planet Earth [electronic resource]

If Earth's entire history could be compressed into a single year, modern humans would've appeared just 23 minutes ago! Use this video to introduce your students to the concept of geological time (also called deep time); relative age dating of rock via the principles of stratigraphic superposition, original horizontality, and cross-cutting; absolute age dating by radioactive decay; the chemical elements, heavy and light, that make up the planet; and Earth's three main layers: crust, mantle, and core.

Plate Tectonics [electronic resource]

Studies of our planet's crust, or lithosphere, suggest that it's not a single solid layer at all. This video illustrates the process of scientific inquiry by studying the evolution of our understanding of plate tectonics, the dynamics of those ever-shifting slabs of earth we call solid ground. Beginning with Alfred Wegener's hypothesis of continental drift, the program discusses major and minor plates, types of plate boundaries, and the concepts of spreading and subduction. Earthquakes and volcanoes are also addressed.

Rocks and Minerals [electronic resource]

Knowledge of the physics and chemistry of the planet's "bones" is essential to a complete understanding of Earth science. Ranging from the Mohs scale and specific gravity to silicates, carbonates, and halides, this video delves deeply into the composition, properties, and classification of rocks and minerals. An element of forensic-type analysis is also brought into play, since any stony formation represents a portion of the planet's history and local conditions.

Oceans and Seas [electronic resource]

More than 70 percent of the Earth's surface is covered by water. Use this video to impress upon your students the importance of the seven seas to people, the marine food chain, and the planet as a whole. Topics include the various kinds of currents and the forces that influence them, tides and waves (what they are, what causes them, and how they're classified), features of the seabed, and the formation and shaping of coastlines. A basic explanation of how oceans have been affected by human activity is also provided.

Geocycles [electronic resource]

Planet Earth is an amazing machine, and we-and our future-are riding on it. This video introduces students to the Earth system's primary interacting subsystems (the biosphere, geosphere, hydrosphere, and atmosphere); the nitrogen, carbon, and water cycles; and three surface processes: weathering, mass-wasting, and erosion. The greenhouse effect, the impact of acid rain on the environment, and diminishing freshwater resources around the world are considered as well.

Atmosphere, Climate, and Weather [electronic resource]

People everywhere are interested in the weather, but how does it all work? Beginning with Earth's atmosphere-its evolution, its gaseous composition, and its four regions-this video takes a close look at how conditions combine to create climate and weather. Topics include the Koppen Climate Classification System; weather prediction; types of clouds and precipitation; thunderstorms, tornadoes, and hurricanes; and weather patterns such as El Nino and La Nina.

Energy and Resources [electronic resource]

As the Earth's fossil fuel reserves decline, what forms of energy will come next? After discussing the formation, uses, and consequences of burning coal, oil, and natural gas, this video explores the development of alternative resources that may someday completely replace them: nuclear power, solar energy, biomass, geothermal energy, hydroelectric power, and wind power. Benefits, costs, and environmental impacts are considered.

Environmental Issues and Human Impact [electronic resource]

This video looks at urgent environmental concerns facing planet Earth and what people can do to repair the degradation humans have caused. Air and water pollution, the effects of pollution on health and the environment, deforestation and loss of wetlands, ozone depletion and global warming, and the negative impact of agriculture, construction, and recreation/tourism are discussed. The program ends with anti-pollution initiatives like recycling and greater energy efficiency. The key message? Individuals can make a difference!
