Geo basics

Introduces students to the concept of geological time, age dating, chemical elements and the three main layers of the earth.

Ranges from the Mohs scale and specific gravity to silicates, carbonates, and halides. Also delves into composition, properties and classification of rocks and moinerals, as well as forencic-type analysis.

Topics include various kinds of currents and the forces that influence them, tides and waves, features of the seabed and the formation and shaping of coastlines. The marine food chain is also stressed.

Takes a close look at how conditions combine to create climate and weather.

"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"--Container.

Discusses the formation, uses and impact of fossil fuels and development of alternative resources including nuclear power, solar energy, biomass, geothermal energy, hydroelectric power, and wind power.

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.
