Topic > The world's total water supply amounts to approximately 332.5 million cubic miles of water, covering approximately 70% of the Earth's surface. With so much water populating our planet, there obviously has to be a way to keep it moving. We call it the water cycle, which has been around longer than we know. The beauty of the water cycle is that it can never stop working because water is always evaporating. In fact, we are now using the same water we used in the beginning of the Earth, thanks to the water cycle. Growing up, we all learned about the water cycle and its three simple phases. These phases were evaporation, condensation and precipitation. Come to find out that there is much more that goes into the cycle than we initially learned. Deposition occurs when a vapor is transformed directly into a solid. Deposition is most frequently observed in frost or snowflakes. While this process is relevant to the water cycle, it is not one that we experience as frequently as some of the other processes and it is certainly not as distinct. The third phase of the water cycle is precipitation. After the molecule returns to its liquid state, something must happen. That “something” is precipitation. According to an article from usgs.gov, in 2015, precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. This is the part of the water cycle that connects water from the atmosphere to the land. The most frequent type of precipitation we experience is rain. Infiltration is another minor process in the water cycle. Infiltration is the process by which water enters the soil and moves around the area into rocks and pore spaces. When water lands on shallow ground, it will move horizontally and vertically. If the ground were deeper, the water could begin to recharge underground aquifers. If that were to happen, people could drill a hole in the ground and start using it as a water source. There are many factors that affect infiltration such as rainfall intensity, soil characteristics, terrain slope and more. Soil can only absorb a certain amount of water at a time. Excess water is considered runoff water, which is surface water that runs away
