Evaporation, Condensation, Precipitation, and Infiltration




Evaporation: The time when water turns into gas and becomes water vapour. Almost all of the water contained in the air. Another way to get water is called transpiration, when there is water loss in plants. But if there's combined water loss in the atmosphere from evaporation and transpiration, it's called Evapotranspiration.













Condensation: This is the opposite of evaporation because water vapour changes from gas to tiny droplets of water that is very hard to see. Those tiny droplets are so hard to see, air can carry it. We recognize them as clouds or fog.











Precipitation: After the process of condensation, while the air are carrying the tiny drops of water, they start to increase in size until the air can't carry them so instead, they drop them, causing precipitation. Although, rain isn't the only type of precipitation but snow, hail and sleet too.










Infiltration: During precipitation, some of the water which falls on Earth may be stored as ice, snow and icebergs but also, the water can be stored underground. How? It's through a process called infiltration. How does it work? The raindrops falls onto the earth, passes through the soil and makes it underground. Although they made it, they usually make its way to lakes or rivers. Then why are there wells and springs if the water's in the lake or river already? Well, that's because some of the water stays underground, and that type of water's called groundwater. It's also another type of storing water.

This is a very well done assignment, Rgee. You've chose graphics well and in your writing identified the process taking place.

You can be very proud of your work when it is done to this standard.
