The Water Cycle
The Hydrologic cycle (water cycle) is a never ending process of recycling water, that has been happening since the beginning of the earth. The process is between land ocean and atmosphere and has four key stages.The four Stages include Evaporation, condensation, precipitation and runoff/ groundwater. The state of the water changes continuously between liquid, solid and vapour.
Evaporation is the process of the water molecules separating and re-forming into a vapour before rising into the atmosphere. The process of evaporation works best on hot days because it is the sun's energy and heat that cause the water molecules to separate so the water evaporates. Evaporation is an invisible process because the water vapour is translucent only recognisable as humidity. The water Vapour rises into the atmosphere where it mixes with dust and forms a cloud or condensation.
Condensation is when water vapour mixes with the dust in the air and forms a cloud. These small clouds group together and make large clouds. As the air gets colder higher up the water vapour cools and forms water again. Eventually the clouds become full of water which causes it to rain; This is called precipitation. There are lots of different types of precipitation this includes: rain, snow, hail and sleet.
Runoff is the is the process of precipitation running downhill or along the surface, getting back to the ocean or a lake. Runoff can be identified as Rivers,creeks or streams. Groundwater is when runoff soaks into the ground and goes through aquifers. In Christchurch we drink groundwater; it is also what we use in our houses for cooking,cleaning and watering our plants.
ConclusionOverall the hydrologic cycle is very important for our planet's survival as much as it is for its inhabitants. The four key stages have become part of our daily lives and we have adapted to these changes.
