Rising air currents take the vapor up into the atmosphere, along with water from evapotranspiration, which is water transpired from plants and evaporated from the soil. Yes, water below your feet is moving all the time, but not like rivers flowing below ground. If you are trying to boil water quickly, it makes sense to begin with a small amount. There are too many variables as basic data to provide an exhaustive answer to the question, how fast does water evaporate? Different liquids will evaporate at different rates because they contain different molecules, which require different amounts of energy to separate them. Thats condensation. If the relative humidity is bigger than 100%, water vapor will condense from the air, becoming dew and/or mist. The Times talked to a couple of physicists about whats really happening. However, if speed is your goal, then it is imperative that you heat your water quickly and evenly, so that as many water molecules as possible are exposed to direct heat. Runoff is nothing more than water "running off" the land surface. The temperature drops to the boiling point ($T=99.6\ \mathrm{^\circ C}$) at the new pressure. A comment above mentioned using a cloth. In conclusion: it is definitely a bitfaster to boil water in a coveredpot. The enthalpy of the water can by increased by any kind of heat transfer. Not only is it necessary to sustain nearly all life on earth, it exists in three distinct states: solid, liquid and gas. It causes your body to remove fluids from your blood through your renal system, which includes the kidneys, ureters, and bladder, at a much quicker rate than other liquids. Only about 10 percent of the water evaporated from the oceans is transported over land and falls as precipitation. Put the pan containing the salt solution on the baking sheet somewhere in a warm place like outside in the sun, or near the window. That adds the area of the cloth to the surface area for evaporation. (the water on top of the pool AND the water on the exterior of the wick material.
