Around 71 percent of Earth's surface is covered by water. Water can also be found in the air as water vapor and even under the ground in aquifers. Without water, humans could not survive, and Earth's plants and animals couldn't survive either. Through this book's exploration of water, readers discover all the places where water can be found. With full color photographs paired closely with approachable text, readers also learn about the power of water on Earth and some water safety information.
