Lakes can be hundreds of miles long and thousands of miles deep—or small enough to swim across! It's common for homes and roads to be built near lakes because they offer such beautiful scenery as well as needed resources. Readers are introduced to the lake biome that may be in their backyard through lakes' main features, animals and plants that may live there, and examples of some of the largest lakes on Earth. Full-color photographs and small maps highlight this special biome as the main content simply touches on key science curriculum topics including food webs and water conservation.
