Summary
Water covers more than 70 percent of Earth’s surface, and all of it is connected in the never-ending water cycle. A substance that can cut through solid rock, destroy cities, sculpt mountains and coastlines, and affect climate, water is a mighty force in nature. The power of moving water, such as in rivers, changes Earth’s landscape, creating valleys and deep canyons over time. In Rivers, Lakes, and Oceans, follow the nonstop journey of water as it rushes along in rivers and streams, travels beneath the ground, rests in lakes, crashes against coastlines, and flows into the ocean.
