A waterfall is a river or other body of water’s steep fall over a rocky ledge into a plunge pool below. Waterfalls are also called cascades. The process of erosion, the wearing away of earth, plays an important part in the formation of waterfalls. Waterfalls themselves also contribute to erosion. Rather than simply telling the reader that the waterfall is beautiful, for example, add details about the colors, shape and size of the waterfall. For example, describe what the water looks like as it falls — that is, whether it bounces off the rocks quickly, flows calmly or drops aggressively. A waterfall is a place in a river where water spills suddenly downward. Waterfalls are known for their beauty and awesome power. The world’s tallest waterfall is Angel Falls, in Venezuela. Its water plunges 3,212 feet (979 meters). burble Add to list Share. To burble is to move with a rippling flow, the way water bubbles down the side of a small garden waterfall. A stream burbles as it travels along its bed, bubbling over rocks and branches. The verb burble captures both the movement of the water and the sound it makes as it moves. Waterfalls are wonders of nature that humans have adored since ancient times. The sight, sound, and feel of waterfalls are what make them so appealing to us. Waterfalls connect and flow into multiple rivers, leading to water purification. This creates a safe environment for fishes and other marine animals. In short, if water doesn’t have sufficient oxygen, marine animals will not survive inside, affecting the ecosystem. Also, a waterfall turns waste into nutrients. Once the negative ions reach our bloodstream, they are said to increase our bodies’ production of serotonin, which is the chemical responsible for relieving stress and depression, and for boosting our energy and happiness. So it’s not surprising we feel so great when we’re around waterfalls
