This activity uses “flubber” to demonstrate the visco-elastic properties of the Earth’s lithosphere and shows isostatic rebound in action.
The key properties of soil (physical, biological, and chemical) determine recreation, crop production, range, water/erosion conservation, forestry, and engineering uses of the soil. Soil surveys help us understand how soils differ and how they behave under various land management systems. The heart of a soil survey is the soil map showing the spatial distribution and variability of soils on the landscape.
