### Upper Elementary Science - I4.2 The Water Cycle

 Water exist in three states of matter - as a solid, liquid, or gas. The water that we drink is liquid, solid form of water is the ice, and when we boil water on a stove, it turns to a gas called steam or water vapour. Due to the heat of the sun, everyday water is evaporating up into the air and then condensing and falling back to the earth. All these movements of water can be drawn as a great big circle, called the water cycle. Everyday water evaporates from the earth, especially from the oceans. As it rises into the sky, the water vapour condenses into little droplets that form clouds. When the droplets get big enough then the water falls back to the earth as some form of precipitation. It fills rivers, lakes and oceans, and some of it soaks into the earth's groundwater. From the rivers, lakes and oceans, water evaporates and rises in to the sky and again the same cycle is repeated. This is the never ending water cycle which goes on and on. Directions: Answer the following questions. Draw a picture and describe the water cycle in your own words
