That’s why we are always looking for water on other planets…where there is water, there is the possibility life.. Soils support the growth of higher plants by providing a medium for plant roots and supplying nutrient elements that are essential to the entire plant.. Soil properties are the principal factor controlling the fate of water in the hydrologic system. Water loss, utilization, contamination and purification are all affected by the soil.. Runoff.
