One important factor in dealing with HC surface and ground water supplies is the differences in surface water flow and tributary ground water flow. In Nebraska, for example, stream-flow may move twenty-five miles per day or more, whereas ground water flow may be 300 feet per year.hen the aquifer is, say, twenty feet higher than the stream, the ground water will flow toward the stream more quickly than if the aquifer is only one foot higher than the stream.
This is the definition of universal solvent and an explanation of why water is considered the universal solvent This is the definition of universal solvent and an explanation of why water is considered the universal solvent
A solvent is a substance which dissolves a solute. When a solvent dissolves into a solute, it creates a solution. If i pour salt into a cup of water. The salt is the solute because it's being dissolved and the water is the solvent because it is doing the dissolving. The saltwater is the solution because that's what the solvent and solute make. A way to remember is that if you spilled salt on the table you need to get rid of it.
