ROOTS HOLD THE SOIL


 * 1) Roots holding the soil is the cosmic work of the roots.
 * 2) Roots are like dikes which hold the earth.
 * 3) The roots form terraces on the hillsides, preventing the erosion of soil.
 * 4) The same work that the roots do is done by farmers when they grow crops on the hillsides, by a method called terracing.

The Fountain of Terraces or Cups


 * 1) The brown represents the soil and the blue, water.
 * 2) Some water is retained by the roots of a plant, and water filters through, slowed by the network of roots and soil, gradually working its way to streams and rivers.
 * 3) This principle of slowing the descent of water on the mountainside has been used in terraced gardens which work like this fountain of cups.
