Images of landscapes illustrate how wind creates features such as dunes, playas, blow-outs, and even oases. Glaciers Many of the world's most beautiful landscapes were made by glaciers.This program shows how, explaining glacial formation, structure, movement, and methods of gouging and accumulating earth.Geophysicists use seismic wave studies, variations in temperature, magnetic fields, gravity, and computer simulations to create models of deep structures. The Sea Floor The mysteries of the ocean floor lie hidden under enormous pressure and total darkness.
Connections are drawn between atmospheric gases, climate change, rock formation, biological functions, and mass extinctions. Minerals: The Materials of Earth Minerals have been indispensable to human civilization.This series shows the physical processes and human activities that shape our planet.From earthquakes and volcanoes to the creation of sea-floor crusts and shifting river courses, Earth Revealed offers stunning visuals that explain plate tectonics and other geologic concepts and principles.The timeline of major geologic events is superimposed onto the year for a condensed view of Earth's evolution.A relationship between this timeline and that of life on Earth is established, with fossils and radiocarbon dating playing a major role in the discovery. Evolution Through Time The fossil record reveals much about the diversity and development of species.
