Water flow refers to the movement of water, whether in rivers, streams, or even in our homes. It is driven by gravity, which pulls water downhill, creating currents. This flow is essential for ecosystems, as it helps transport nutrients and supports various forms of life, including plants and animals. In our daily lives, we experience water flow when we turn on a faucet or shower. The plumbing system in our homes is designed to manage this flow, ensuring we have access to clean water for drinking, cooking, and bathing. Understanding water flow helps us appreciate its importance in both nature and our everyday activities.
