Visions of Earth, by AGI
82 High-definition animations showing a variety of Earth and space system processes.

Urban Sprawl in China, by TERC
These images show the region around Shenzhen, China from 1988 to 1996. Series of images such as these that show the same location taken over time are referred to as temporal data. Notice as new roads, bridges, and buildings are added to the landscape in each new image. Examine changes to the coastline and the amount of sediment in the water. Look for other things that change over time in these images.

Urban Sprawl: Phoenix, by American Museum of Natural History
View a video of urban sprawl in Phoenix, AZ.

Urban Heat Island, by NASA
View a short video that illustrates what an Urban Heat Island is.

Rain, Drought, Urbanization Contributing Factors for Storms, by NASA
The animation shows how, in the days leading up to March 14, 2008, pockets of rain fell between drought-ravaged areas that saw no rain, setting up boundaries of dry and moist air. These boundaries along with urban-rural land cover boundaries produce circulations and rising air similar to a sea breeze. They may also serve as localized regions of enhancement for existing storms or initiation of new storms. Modeling studies suggest that these boundaries may have been a factor in the storms that produced the Atlanta tornado.
