Drip Drop, Water's Journey takes you on water's journey beginning in rivers, lakes, and oceans, moves through water-treatment centers, along underground tunnels into the pipes in your house or apartment building, and out through the faucet in your bathroom or kitchen. After you have used it, water runs down the drain and out of the house, through underground sewer pipes and back to the water-treatment center. The book tells how a water-treatment center cleans water. After treatment, the water can be used again.
Water can take many forms.
It can be a liquid , a solid , or a gas . Water travels in a continuous path through Earth and its atmosphere, called the water cycle . The journey begins in Earth's oceans. As the Sun heats the ocean, the water evaporates , turning into a gas. Sometimes this gas meets cooler air, and the gas changes into drops of water.
