Images of Earth & Space II
34 minutes 1998 Level: Grades 9-undergrad 1/2" VHS
Uses computer simulations to tour the solar system and outer space. At the Sun, simulations investigate processes that create magnetic fields and release energetic particles. Earth science begins with the Pacific Ocean studying the 1997-98 El Nino and Cyclone Susan. Crossing the globe, visualizations trace North America's East Coast and ocean currents in the North Atlantic Ocean. The night light from the world's cities then shows human impact. Next, two models probe nearby space phenomena, fluid behavior in microgravity conditions, and an asteroid collision. A jaunt to Mars explores the mountains and trenches of its dry, rocky exterior. The video concludes at a binary neutron star system, where two city-sized objects with the Sun's mass merge in a titanic explosion.
