Water Cycle

I'm still remember about my presentation when i was form 5, my friend and I were acting about water cycle that undergo lot of processes. It was really fun as we made lot of caps by using manila-card to represent what type of water in that time. From lake, we were evaporated(water's cap), then we felt cold (snow's cap), n etc. We got highest mark for that proficiency test by getting full mark in each assessment. I felt so amaze with that mark.. Hahaha =). Now let me tell you more details about water cycle. This cycle is made up of a few main parts. First is evaporation. Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air. Then, water vapor in the air gets cold and changes back into liquid, forming clouds. This process is called condensation. After that, the water undergo precipitation. This process occurs when so much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow. When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land. When it ends up on land, it will either soak into the earth and become part of the “ground water” that plants and animals use to drink or it may run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again.. Don't be shocked if i say that maybe some of your drinking water source is come from others' urine waste!! Hahaha!! =p
