The Earth Science Enterprise Educational CD-ROM is a myriad of images, animations, and narrations on the four major topics that are emphasized by the program including the Earth's atmosphere, land, ice and oceans. The presentation of these topics range from general to a more detailed and scientific approach suitable for high school and undergraduate university curriculums.
Both natural and human-induced changes to our global environment are beautifully illustrated, and narrated. The Earth Science Enterprise CD-ROM travels the globe -- From deforestation and habitat loss on land, to the vital production of phytoplankton in the ocean, to the instability of arctic glaciers, to the Earth's interaction with the sun's energy.
Also included are overviews of the many components of the Earth Science Enterprise - including Landsat 7, Terra (formerly EOS AM-1). NASA's first two Earth Observing System satellites, data information, and educational resources.
