Soil Profile. There are different types of soil, each with its own set of characteristics. Dig down deep into any soil, and youâll see that it is made of layers, or horizons (O, A, E, B, C, R). Put the horizons together, and they form a soil profile. Like a biography, each profile tells a story about the life of a soil. Most soils have three major horizons (A, B, C) and some have an organic horizon (O).
At a pilot facility in Singapore, Siemens has cut the energy needed to desalinate seawater by more than 50 percent. The plant processes 50 cubic meters of water per day, consuming only 1.5 kilowatt-hours of electricity per cubic meter.
The driving force for the hydrologic cycle is the sun, which provides the energy needed for evaporation like the flame for a gas stove gives the energy for water to boil water â¦ and make steam. Water changes from a liquid state to a gaseous state as it evaporates from the oceans, lakes, streams, and soil. The oceans are where the most water is so that's where most of the evaporation happens.
