Water Cycle
Welcome
Welcome: Water Cycle
Description:
Run and get a glass of water and put it on the table next to you. Take a good long look at the water. Now -- can you guess how old it is?water cycle knightwater cycle dinosaurThe water in your glass may have fallen from the sky as rain just last week, but the water itself has been around pretty much as long as the earth has!When the first fish crawled out of the ocean onto the land, your glass of water was part of that ocean. When the Brontosaurus walked through lakes feeding on plants, your glass of water was part of those lakes. When kings and princesses, knights and squires took a drink from their wells, your glass of water was part of those wells.And you thought your parents were OLD

Description: You will learn about "Water Cycle" in this video. The Sun heats up the water from oceans, lakes and rivers and water changes into water vapour by the process of evaporation. Plants also lose water in the form of water vapour from their leaves into the air by the process of transpiration. As the water vapour rises up into the air, it starts cooling down and forms tiny water droplets. These water droplets come together to form clouds. This process is called condensation When the clouds start getting heavy and cannot hold the water droplets anymore, they fall back to the earth in the form of rain, hail or snow. This process is called precipitation. Some of the water that falls on the earth seeps into the ground. This water is available to us in the form of groundwater. The remaining water falls back into oceans, lakes, rivers and seas. This process is called collection. Then, the sun starts heating up this water once again. This circulation of water is called water cycle.
Water cycle third step
Description: Precipitation comes in the form of rain, hail, and snow! The clouds that condense get too heavy--they are filled with so much water! So when you see water falling from the sky, you know its precipitation at work!
Water cycle second step
Description: This invisible vapor, mostly coming from the world�s oceans, travels up into the atmosphere and condenses, forming clouds.
