Water Cycle


1.Evaporation- As you can see in this picture, the water is heated by the sun and becomes water vapour and flys into the sky. We call this process, 'Evaporation'. If there is higher temperature, less humid and stronger wind, then the evaporation occurs actively. This is the first step of the water cycle.








2.Condensation- If we look at this picture, we can find out that water droplets are formed outside the glass when water vapour in the air condenses on the cold glass. When the air cools down, the water vapours that are floating in the air becomes water droplets. We call this process, 'Condensation'. This is the second step of water cycle.



3.Precipitation- When we look at this picture, we can figure out that precipitation occurs when the heavy water droplets then fall back to the ground as rain, snow, hail or freezing rain. This is the third step of water cycle.




4. Infiltration- By looking at this picture, we can find out that water soaks into the soil from the ground level. We call this process, 'Infiltration'. However some water remains on the ground because there is not enough space to soak into the ground. When the sun shines, the evaporation begins with a new water cycle and ends again with infiltration.

Young Woo, this is very well done. You've got some original graphics I've not seen yet. They strongly show the content, plus your explanations are very fine.

Keep up the good work.

Young Woo, I think you did a great job on this blog post.

Just saying, but you have the same graphic as me in condensation.

Nice job!!!
