Raindrops fall around the world onto cities and forests and fields They sink into soil and plop into puddles Eventually in a day or a month or over many years the water will find its way to the ocean Earth’s ocean covers most of the planet’s surface The oceans are so vast that when astronauts look down from space Earth looks mostly blue But Earth’s water doesn’t just sit there It’s in motion even within the ocean I travel all around the ocean from the Come on let’s explore the world of water Arctic to Antarctica and back 5
Our Watery World not water 29 water 71 We usually think of Earth as well earth meaning dirt or dry ground But Earth is mostly water How much water Enough to cover 71 of the globe Scientists estimate that all the water on Earth adds up to about 326 million trillion gallons 326,000,000,000,000,000,000 gallons That’s this much 1,234,000,000,000,000,000,000 L What activities use the most water Could you reduce how much you use On average you use this much water for washing hands 1 gallon 3 8 L brushing teeth with water running 1 5 gallons 3 8 18 9 L a shower 2 5 gallons per minute 9 5 L fl ushing toilet 3 gallons 11 4 L a bath 36 gallons 136 3 L 6
