Angle of repose

The angle at which material will beginto move downhill. For soils, this anglewill change (i.e. decrease) when wet.

San Jose, CA

This pair of images illustrates the rapid growth that occurred between 1973 and 1999 in San Jose, CA. From 1970 to 1996, the population of the city of San Jose increased from 459,000 to 839,000. This is reflected by an increase in urban areas in the above Landsat images, which show up as light blue.
