A soil survey should list the coefficient of linear extensibility (COLE) value. [2] Professional soil scientists can also analyze samples of a soil to determine its shrink-swell capacity. [2] Expansive soils will form large cracks, in roughly polygonal shapes, on the surface of the soil during dry periods. [3]
Expansive clay, also called expansive soil, is a clay soil prone to large volume changes (swelling and shrinking) directly related to changes in water content. [1] Soils with a high content of expansive minerals can form deep cracks in drier seasons or years; such soils are called vertisols .
Such maps are typically richer in context and show higher spatial detail, yet are not necessarily more accurate than traditional soil maps. Soil maps produced using (geo)statistical technique can also include an estimate of the model uncertainty. [3] An example of a traditional soil map showing soil mapping units, described soil profiles and ...
Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.

San Joaquin soil profile San Joaquin soil landscape. San Joaquin is an officially designated state insignia, the state soil of the U.S. state of California.. The California Central Valley has more than 500,000 acres (2,000 km 2) of San Joaquin soils, named for the south end of that valley.
ChronoZoom is a free open source project that visualizes time on the broadest possible scale from the Big Bang to the present day. [1] Conceived by Walter Alvarez and Roland Saekow and developed by the department of Earth and Planetary Science at the University of California, Berkeley in collaboration with Microsoft Research and Moscow State University, Alvarez unveiled the first ChronoZoom ...
A state soil is a soil that has special significance to a particular state. Each state in the United States has selected a state soil, twenty of which have been legislatively established. These official state soils share the same level of distinction as official state flowers and birds. Also, representative soils have been selected for Puerto ...
